Mussaenda treutleri Stapf ??

Mussaenda …. ????

Please ignore image CSC_0006.JPG


I did check before. By the way 3 Mussaenda sp are found
in the Kathmandu Valley: M. macrophylla, M. roxburghii and
M. treutleri.
Could it be M. treutleri ??

Does not match with images at Mussaenda macrophylla (only species available in efi from three pointed out by you)

What about any one sp. as listed in Nepal as below:

Try to check on the net. Sepals are quite diagnostic in this genus.


Looks like Mussaenda roxburghii

Thank you …! Mussaenda roxburghii Hook.f.


MUSSAENDA HIRSUTISSIMA( MUSSAENDA FRONDOSA ): 4 images.
Attaching few images of Mussaenda hirsutissima (mussaenda frondosa).


Where and were the images clicked ?
It does not match with either Mussaenda hirsutissima or Mussaenda frondosa
It may be Mussaenda parryorum as per images herein and as per GBIF specimens one and two.


When?


The images were taken at Rajabhatkhawa forest (North Bengal)..


The images were taken on 19-4-21.


In fact all details like place and date were written on the images.


It is more likely to be Mussaenda roxburghii Hook.f., as per images and details herein, as Mussaenda parryorum C.E.C.Fisch. does not have distribution in the area.



/wp-content/uploads/2020/10/mussaenda%20Sikkim.jpg

mussaenda Sikkim:
mussaenda seen in Sikkim. A small under herb or a small shrub
Species name, some of you may know. Please post.


mussaenda luteola


Check Mussaenda treutleri Stapf which is common. There are one or two more species listed in Plant genetic resources of Sikkim by Raju et sanjappa Bull.Bot Surv.Ind 1994 accessible on Net


Could be Mussaenda roxburghii, not sure though.


Please check if Mussaenda erosa is found in Sikkim?


Image not clear.
May be Mussaenda roxburghii Hook.f., as per images and details herein.

Mussaenda …???

Maybe Mussaenda frondosa L. as per images and details herein.


Or rather Mussaenda roxburghii Hook.f., considering the size of the calyx lobes.


Yes … Looks correct ID !


IBP in its description says:
Berries subglobose, ca. 1.8 cm in diam., sparsely appressed pubescent.
While Flora of Bhutan says as Berry globose, 6-10mm, glabrous, calyx persistent until fruit is ripe.
Maybe the berries become glabrous on ripening.


.


Mussaenda roxburghii in FOI:
I think images of Mussaenda roxburghii in FOI by you and others are of  Mussaenda frondosa L. rather than those of Mussaenda roxburghii Hook.f., as per images and details herein.
Pl. correct.


I guess you are right


That’s a difficult one … Our images agree with the following features of Mussaenda roxburghii, filliform sepals and filliform tips of the petals. I find the sepals of Mussaenda frondosa broader in comparison to our images. Also the buds look different from those of M. frondosa. Our buds appear to agree with the M. roxburghii images on Flora of Bhutan site
  https://biodiversity.royal_manas_national_park/observation/60
If you can point me to some features of M. roxburghii which do not agree well with our images, I will be happy.

As the images are from three places, if you post detailed images from each place, it will be nice.

This may be Mussaenda frondosa as per discussions and keys at Amboli, MH :: Mussaenda for ID :: ARK2021-110 and as Mussaenda glabrata has only distribution in Western India as per POWO and BSI Flora


Taking it as Mussaenda roxburghii, as per discussions at Mussaenda roxburghii?

Sorry !! Not available sir


Please post multiple images covering all aspects of the sp. like habitat, leaf upper/lower side,
inflorescence, flower image from different angles, leaf position on stem, stipules and stem as well
for easy ID !


I concur with … suggestion. This would help proper ID.


Mussaenda glabrata (Hook.f.) Hutch. ex Gamble !

Is this a Mussaenda frondosa?

I guess it is matching !


Yes. I too have photographed in Western ghats area near Shimoga.

Mussaenda roxburghii?: 5 high res. images.
Found this plant growing by riverside in Pasighat, Arunachal Pradesh in May end.
I think this is Mussaenda roxburghii. Looking for confirmation or otherwise id suggestions.


Mussaenda frondosa L. !


To my eye, the sepals of Mussaenda frondosa look broader in comparison to my images, and also more hairiness of the plant. Also the buds of my plant look different from those of M. frondosa. The buds of my plant appear to agree with the M. roxburghii images on Flora of Bhutan site

I think the main difference appears to be in Calyx lobes:
For Mussaenda frondosa, it is ‘Calyx with hypanthium portion ellipsoid, 3-4 mm, strigose to sericeous; lobes narrowly triangular to narrowly ligulate, 7-12 mm, hirsute, acute to acuminate’ as per Flora of China.
For Mussaenda roxburghii, it is ‘Calyx lobes filiform, tapering from base, 6-9mm x 1mm, densely covered in long silky hairs’ as per Flora of Bhutan.
Let us see the detailed description to arrive at the right id:
Flora of Bhutan:

Mussaenda roxburghii Hook.f.:

Much branched shrub 1-4.5m. stems glabrous or pilose with spreading hairs leaves petiolate usually elliptic, rarely ovate or oblong, 5-25 x 4-9cm, acuminate at both ends, subglabrous or thinly pilose above, thinly to densely pilose below, veins adpressed pilose on both surface; petioles 2-15mm; stipules broadly triangular, 6-10mm. Inflorescence a dense terminal head, usually 3 branched from base, but differentiated, many flowered. Calyx lobes filiform, tapering from base, 6-9mm x 1mm, densely covered in long silky hairs. Corolla tube 2.4-2.8cm, densely covered in long silky hairs. lobes narrowly ovate, 4-8 x 2-2.5mm, terminating in a long fine hairpoint. Berry globose, 6-10mm, glabrous calyx persistent until fruit is ripe.

From IBP:
Shrubs, up to 8 m tall; branchlets striate, angular, greenish, densely pubescent. Leaves simple, opposite decussate; stipules ca. 0.5-2 x 0.4-0.8 cm, triangular, acuminate; petioles ca. 0.5-1.5 cm long, densely hairy; lamina ca. 5-20 x 3-9 cm, oblong-lanceolate, acute to acuminate at base, acuminate at apex, entire, pubescent underneath; secondary nerves 6-12 pairs. Flowers white, ca. 0.4-0.6 cm across in terminal subcapitate cymes; peduncles pubescent; bracts ovate, ca. 0.8 x 0.3 cm, acuminate; clayx lobes filiform, ca. 0.6-1 x 0.1-0.2 cm; petaloid sepals oblong-lanceolate, ca. 4-10 x 2.5 cm with 1-4 cm long stalk; corolla-lobes ovate, ca. 0.2-0.1 cm, acuminate. Berries subglobose, ca. 1.8 cm in diam., sparsely appressed pubescent. Seeds ellipsoid or globose, reticulate.

Flora of China:

Mussaenda frondosa Linnaeus:

Climbing shrubs; branches terete to compressed, moderately to densely pale red sericeous to hirsute becoming glabrescent, red-brown or brown, rather densely lenticellate. Leaves opposite; petiole 4-10 mm, densely sericeous; blade drying thinly papery or leathery, adaxially dark green to brownish green, abaxially pale green to yellowed, broadly elliptic, elliptic-oblong, ovate, or oblanceolate, 8-15 × 3-8 cm, both surfaces sparsely strigillose on lamina and strigose to sericeous on principal veins, base acute, obtuse, or rounded, apex acute to caudate-acuminate; secondary veins 7-10 pairs, tertiary venation visible and reticulate; stipules persistent, triangular, 5-10 mm, densely strigose to pilose, deeply 2-lobed, lobes lanceolate to narrowly triangular, acute to acuminate. Inflorescences congested-cymose becoming lax with lateral axes elongating markedly, 4-8 × 8-20 cm with lateral axes to 8 cm, sparsely to moderately pubescent with 2 types of pubescence, mixed strigillose to appressed puberulent and hirsute to villous, pedunculate or sessile and 3-partite; peduncles 1-3 cm; bracts triangular or elliptic, 4-10 mm, usually 2- to multifid, acute to acuminate; pedicels 1-6 mm. Flowers pedicellate, biology not noted. Calyx with hypanthium portion ellipsoid, 3-4 mm, strigose to sericeous; lobes narrowly triangular to narrowly ligulate, 7-12 mm, hirsute, acute to acuminate, with 1 lobe of 1-4 flowers per inflorescence sometimes expanded into calycophyll, blade elliptic-oblong to ovate, 6-8 × 2.5-5 cm, both surfaces glabrescent on lamina and strigillose on principal veins, base acute to cuneate, stipe 10-30 mm, apex acute or acuminate. Corolla salverform, outside hirsute; tube 22-25 mm; lobes ovate, 6-7 mm, acuminate. Berry ovoid or ellipsoid, ca. 10 × 7 mm, strigose to glabrescent, calyx limb deciduous. Fl. Apr-May.

After going through the descriptions, I feel it may be Mussaenda roxburghii Hook.f. only.

The following posts may also be of Mussaenda roxburghii Hook.f..:

Mussaenda frondosa?
