Tarenaya hassleriana

Cleome hassleriana, commonly known as spider flower or spider plant,^[1] is a species of flowering plant in the genus Cleome of the family Cleomaceae, native to southern South America in Argentina, Paraguay, Uruguay, and southeast Brazil.^[2]

Cleome gynandra L. with white flower from Kamrup district:
Attached images are Cleome gynandra L. with purple flower growing with same species (?) bearing white coloured flower in the same place. I have already sent the detail images of Cleome gynandra L. with purple flower.

Date : 25.01.2013

Location: Kamrup district

Family : Cleomaceae

Genus & species : Cleome gynandra L

Habitat: Grows wild on roadside

Habit : Undershrub

Flower : Pure white

Beautiful pictures! But it doesn’t look like C. gynandra to me. It may be C. speciosa (the accepted name is Cleoserrata speciosa as per TPL).

This is Tarenaya hassleriana (Syn: Cleome hassleriana Chodat) as the stamens are inserted in the bottom as per discussions at Cleome gynandra L. from Kamrup district, Assam

Yes this is Cleome houtteana Schltdl.(Syn. Tarenaya hassleriana (Chodat) Iltis).

Cleome gynandra L. from Kamrup district, Assam:

Date : 24.01.2013

Location: Kamrup district, Assam

Family : Cleomaceae

Genus & species : Cleome gynandra L.

Habitat: Grows wild on roadside near ditches

Habit : Erect, undershrub. Pungent smelling.

Flower : Pink to purplish, androphore and gynophore present.

Both of this and the white-flowered form look like Cleome speciosa (now Cleoserrata speciosa) to me. Please check. Very nice pictures!

I agree with … It seems to be Cleome speciosa.

---

I think this species is not Cleoserrata speciosa. It is  Cleome houtteana Schltdl  (=Cleome hassleriana Chodat). Presence of  one pair of stipular spine at the base of each petiole of the leaf and  spines in the midrib of abaxial surface of leaflets is prominent; flower pink to whitish in colour (after examination of the species). In Assamese it is known as Siyalkatahiya. So please validate.

No it is

As per efi thread :
Stamen colour purple in Tarenaya hassleriana & green in Cleoserrata speciosa
Stamens are inserted together in a club-like stub above the bottom in Tarenaya hassleriana, while these are inserted in the bottom in Cleoserrata speciosa.

I do not agree with you Sir. After observation of my new specimen collected on 22.04.24 ( uploaded) from the same place from where I collected my earlier uploaded specimen . Observation of my newly uploaded specimen shows some diagnostic characters i.e. 1. presence of nodal spines[Image 4,5] (absent in  Cleoserrata) i.e.  one pair of stipular spine at the base of each petiole of the leaf and also a few spines are also found in the petiole.2. Leaflet 7 [image 2,3](5-9 in Cleoserrata)  3. Androgynophore absent[Image 6](present in Cleoserrata). 4. stamen 04, purple[Image 6]; only gynophore present[Image 6]. From this observation it is concluded that my specimen uploaded today and earlier are Cleome houtteana Schltdl.(=Tarenaya hassleriana) not Cleoserrata speciosa . So please validate.
6 images.

Due to genus keys at Flora of China, insertion of stamen becomes very important. Stamens are inserted together in a club like stub above the bottom in Tarenaya hassleriana, while these are inserted in the bottom in Cleoserrata speciosa.  

So it is C.speciosa.

---

According to Neto et al. (2017) Cleome speciosa Raf. (=Cleoserrata speciosa)is devoid of stipule i.e. no stipular spine(nodal spine) and possess androgynophore (file attached). But my specimen i.e. Cleome houtteana(=Tarenaya hassleriana) has stipular spine  and devoid of androphore, only gynophore present. Please clarify. Moreover, Choudhury (2005) and Barooah and Ahmed (2014) mentioned five species of the genus Cleome – C. angustifolia, C. burmanii, C. gynandra, C. rutidosperma and C. viscosa from Assam. Recently there is a report of distribution of an additional species of Cleome i.e. Cleome houtteana from Assam  by Das et al. (2022)[file attached). So please validate my specimen.

As per Flora of China:

2 (1)	Androgynophore 5-10 mm; gynophore 2-6 cm; nodal spines absent.		2 Cleoserrata
+	Androgynophore absent; gynophore 4.5-8 cm; nodal spines present (prickles often present on petiole and major leaf veins).		3 Tarenaya

Due to genus keys at Flora of China, insertion of stamen becomes very important. Stamens are inserted together in a club like stub above the bottom in Tarenaya hassleriana, while these are inserted in the bottom in Cleoserrata speciosa. – I think in view of the keys my this interpretation is wrong.

It should be Stamens are inserted together in a club like stub above the bottom in Cleoserrata speciosa, while these are inserted in the bottom in Tarenaya hassleriana. – I think in view of the keys this should be the correct interpretation.
Am I right now? If so, I have to interchange all the images at both the pages.

---

Your interpretation is right Sir. So it is Cleome houtteana Schltdl. (=Tarenaya hassleriana). Now You may interchange all the images at both the pages.

Cleoserrata speciosa and Tarenaya hassleriana- differences : 10 posts by 4 authors.

Cleoserrata speciosa and Tarenaya hassleriana looks quite close in efi site.

I tried to find the difference between the two, but unable to get them.

As per efi thread:

The sepals are glabrous (Tarenaya hassleriana) or glandular hairy (Cleoserrata speciosa);

But I find this character difficult to see clearly.

On further searching, I got both species in Flora of North America as per details below:

Cleoserrata speciosa (Rafinesque) H. H. Iltis:

Plants 50-150 cm. Stems unbranched or sparsely branched ; (fluted), glabrous or sparsely glandular-pubescent. Leaves: petiole 2-12 cm ,(glandular-pubescent); leaflets 5-9, blade narrowly lanceolate-elliptic, 6-15 × 1-5 cm, margins entire or serrulate, apex subobtuse, surfaces glabrate to glandular-pubescent. Racemes 15-50 cm (20-60 cm in fruit, glandular-pubescent); bracts unifoliate, ovate-cordate, 3-18 mm. Pedicels 10-50 mm, (glabrous). Flowers: sepals persistent, green, lanceolate, 4-7 × 0.8-1.2 mm, glandular-pubescent; petals usually brilliant pink to purple, fading to pink or white, rarely initially white, ovate, 15-42 × 8-11 mm, clawed; stamens green, 40-85 mm, (filaments adnate to gynophore 1/3-1/2 of length); anthers 6-10 mm; gynophore 30-85 mm in fruit (filament scars visible ca. 1/4 of length); ovary 6-10 mm; style 1-1.2 mm. Capsules (irregularly contracted between seeds) 60-150 × 3-5 mm. Seeds pale green to brown, 2.5-3.5 × 1-1.2 mm, tuberculate.

FoC illustration

Tarenaya hassleriana (Chodat) H. H. Iltis:

Plants (50-)100-200 cm. Stems sparsely branched; glandular-pubescent. Leaves: stipular spines 1-3 mm; petiole 2.5-7.5 cm, glandular-pubescent, with scattered spines 1-3 mm; leaflets 5 or 7, blade elliptic to oblanceolate, 2-6(-12) × 1-3 cm, margins serrulate-denticulate, apex acute, surfaces glandular-pubescent abaxially, glandular adaxially. Racemes 5-30 cm (10-80 cm in fruit); bracts unifoliate, ovate, 10-25 mm. Pedicels 20-45 mm, glandular-pubescent. Flowers: sepals (reflexed after anthesis), green, linear-lanceolate, 5-7 × 0.8-1.3 mm, glabrous; petals usually pink or purple, sometimes white (or fading to white by second day), oblong to ovate, 20-30(-45) × 8-12 mm; stamens purple, 30-50 mm; anthers 9-10 mm; gynophore 45-80 mm in fruit; ovary 6-10 mm, glabrous; style 0.1 mm. Capsules (25-)40-80 × 2.5-4 mm, glabrous (in straight alignment with gynophore and pedicel). Seeds 10-20, 1.9-2.1 × 1.9-2.1 mm, tuberculate.

I have highlighted the difference between the two, which can be observed in bold.
I shall be reviewing all our posts based on these differences. Hopefully we are able to sort our species.

Giving details from Flora of China:

Cleoserrata speciosa (Rafinesque) Iltis:

Herbs, annual, 0.5-1.5 m tall. Stems simple or sparsely branched, fluted, glabrous or sparsely glandular pubescent. Petiole 2-12 cm, glandular pubescent; leaflets (3 or)5-9; leaflet blades narrowly lanceolate-elliptic, 6-15 × 1-5 cm, both surfaces glabrate to glandular pubescent, base attenuate, margin entire or serrulate, apex acuminate. Inflorescences 15-50 cm but 20-60 cm in fruit, glandular pubescent; bracts narrowly ovate-cordate, 0.3-1.8 cm. Pedicel 1-5 cm, glabrous. Sepals green, lanceolate, 4-7 × 0.8-1.2 mm, equal, distinct, persistent, glandular pubescent, base cuneate, margin entire. Petals brilliant pink to purple but fading to pink or white by second day, rarely initially white, ovate, 1.5-4.2 × 0.8-1.1 cm, clawed. Androgynophore ca. 4 mm at anthesis; stamens 4-8.5 cm; anthers 6-10 mm. Pistil 6-10 mm; style 1-1.2 mm. Fruit gynophore 3-8.5 cm, with scars from filaments on ca. 1 cm of androgynophore and visible on ca. 1/4 of its length; capsule cylindric but irregularly contracted between seeds, 6-15 cm × 3-5 mm. Seeds 10-30 per capsule, pale green to brown, subspherical, 2.5-3.5 × 1-1.2 mm, tuberculate. Fl. Aug-Nov, fr. Sep-Dec.

Tarenaya hassleriana (Chodat) Iltis:

Herbs, annual, (0.5-)1-1.5 m tall. Stems branched, glandular pubescent. Stipular spines 1-3 mm. Petiole 2.5-7.5 cm, glandular pubescent, with scattered 1-3 mm spines; leaflets 5 or 7; leaflet blades elliptic to oblanceolate, 2-6(-12) × 1-3 cm, abaxially glandular pubescent, adaxially glandular, margin serrulate-denticulate, apex acute. Inflorescences 5-30 cm but 10-80 cm in fruit, pedunculate; bracts ovate, 1-2.5 cm. Pedicel 2-4.5 cm, glandular pubescent. Sepals green, equal, distinct, linear-lanceolate, 5-7 × 0.8-1.3 mm, reflexed after anthesis, persistent, glandular pubescent, margin entire, apex acuminate. Petals pink to purple but infrequently white or fading to white by second day, oblong to ovate, 2-3(-4.5) × 0.8-1.2 cm, clawed. Stamens purple, 3-5 cm; anthers green, 9-10 mm. Pistil 6-10 mm; style ca. 0.1 mm. Fruit gynophore 4.5-8 cm; capsule (2.5-)4-8 cm × 2.5-4 mm, in straight alignment with gynophore and pedicel, glabrous. Seeds 10-20 per capsule, dark brown to black, triangular to subspherical, 1.9-2.1 × 1.9-2.1 mm, tuberculate. Fl. (Apr-)May-Dec, fr. Jun-Dec.

I find some difference between the two floras.

Flora of China gives the following keys

Androgynophore 5-10 mm; gynophore 2-6 cm; nodal spines absent- Cleoserrata

Androgynophore absent; gynophore 4.5-8 cm; nodal spines present – Tarenaya
(prickles often present on petiole and major leaf veins).

Commendable job, …
It happens with me …whenever I see a beautiful flower/plant, I forget everything botanical. All I see and record is beauty, and miss all the details. Later on I regret missing all the botanically relevant data. Sometimes I get to pay a second visit, more often I cannot.
I am sure it happens with others too. This is the reason inspite of having plenty of images we falter on decisively identifying at species level. With inadequate data and more not coming forth, at times I advise members to stop at Genus and stop guessing species, on facebook.

---

On going through all the posts in efi site, I find that illustrations given in the above links can be misleading.

So what really is the simple thing which we can see in our flowers and that should be the key in photographs ?

After studying all details, I find stamen colour is quite convincing. Stamen colour purple in Tarenaya hassleriana & green in Cleoserrata speciosa

Due to genus keys at Flora of China, insertion of stamen becomes very important. Stamens are inserted together in a club like stub above the bottom in Tarenaya hassleriana, while these are inserted in the bottom in Cleoserrata speciosa.
Now I will correct all the posts based on this.

---

Great efforts to find the species !!!! For a non-botanist like me leave aside species, confirming Genus itself is difficult. o then minute details of species is overlooked many a times. keep forgetting the similarities and differences between the species and  land in confusion :-).
Thanks to all the stalwarts from this wonderful group giving guidance and tips to me all the time.

---

we need to come to some distuinshing features for practical reasons. cant find papers thru bing. may be some taxonomist can help please

---

I have no doubt about what I have stated after one day of research and these are based on very reliable documents like efloras and after studying more than 50 posts in efi site.

---

I did this exercise as there were no keys or differences to be found in net and I found lot of confusion everywhere including those in efi and foi.

---

And it is not only my one day, but also many days of observations (which are there in efi site) by different members.
It is just like collecting hundreds of specimens from different parts of the country at different times.

---

I have earlier wrongly interpreted the keys.
It should be Stamens are inserted together in a club like stub above the bottom in Cleoserrata speciosa, while these are inserted in the bottom in Tarenaya hassleriana. – I think this should be the correct interpretation.

Cleome speciosa in FOI :

Image of Cleome speciosa in FOI should be of Tarenaya hassleriana (Chodat) H. H. Iltis as per efi thread.
Pl. correct.

---

This is getting more confusing.

I cant believe diagnosis can be based on stamen color only

Thanks …, for sorting out Cleome hassleriana and Cleome speciosa. … is rightly perplexed. I think one need not go into stamen color. The most easy to note difference between the two is that the petals are clawed in Cleoserrata speciosa, and they are not clawed in Tarenaya hassleriana. What is meant by clawed is that the petals are suddenly constricted at the base, having an apparent “stalk”. FOI images of these will be corrected in shortly.

Both can clawed as per Flora of China.

Cleoserrata sp ?? /species/a—l/cl/cleomaceae/cleoserrata

After searching, finally I found that this is Cleome gynandra (Capparidaceae), Could you please confirm it.

Cleome speciosa.

It looks like Tarenaya hassleriana to me.
Please check if the sepals are glabrous (T. hassleriana) or glandular hairy (Cleoserrata speciosa).

---

Thank you for your feedback, I have attached a cropped version of the same pic.

The sepals seem to be slightly hairy, therefore this may be Cleoserrata speciosa..
Could you please confirm?

---

Thanks for the close-up picture of flowers. Yes, your ID Cleoserrata speciosa is confirmed now 🙂

if read … thread and look at the illustrations there are links in his writing, you will get a lot of insight

efi thread

those illustrations show that side views of the inflorescence and preferably whole plants are necessary.

the differences become very obvious then.

do you have more pictures?

---

better info to add to all the discussions

see … response in this thread: https://mail.google.com/mail/….Th

---

Though insertion point of stamens are not clear, first should be Tarenaya hassleriana & 2nd should be Cleoserrata speciosa based on stamen colour and colour of the petals.

---

Both the pictures were taken at the same location, same time.
That’s the reason I posted them together. Thanks for the suggested ids.
