Could it be some species of Flemingia ?

Flemingia species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available on net)

I think it may be Flemingia prostrata, as posted by … at Flemingia prostrata Roxb.Junior ex Roxb. submission AS2 January 2023 and as per description in Flora of China.
The Description of Flemingia macrophylla looks a bit different as per Flora of China and as per GBIF specimens.

Yes …, its Flemingia prostrata Roxb.Junior ex Roxb.

.

Flemingia prostrata Roxb.Junior ex Roxb. submission AS2 January 2023: 6 high res. images.
Here’s a new addition to eFloraofIndia website.
Flemingia prostrata Roxb.Junior ex Roxb.
Family – Fabaceae
Specific epithet ‘prostrata’ refers to prostate growing habit of this species which can be seen in attached images.
Photographed in Hamirpur district, Himachal Pradesh
In April 2022

Yes, appears so as per GBIF specimen.
I think there are many other observations in eFI site, wrongly identified earlier.
I will forward them again, pl. give your views.

SK 3261 25 December 2021: 3 very high res. images.

Location: Surkhet, West Nepal

Altitude:  438m.

Habit : Wild
Flemingia macrophylla (Willd.) Kuntze ex Merr. ??

Maybe.
I am not getting sure about the glands on the calyx from the closeup.

---

Legumes looks different.

---

Is ID OK, …

---

This is Flemingia prostrata.

---

Many other posts from you at F.macrophylla may also be this species.
Pl. check.

Which Fabaceae ??

---

A Flemingia sp. (Fabaceae).

---

Pl. check Flemingia semialata

---

Inflated pod indicates it as Crotalaria

---

Tends to match more with F. macrophylla since sepals and seed pod cover are hairy compared to F. semialata as well as leaves seems to be very rough in this case.

On the other hand F. semialata is not listed in Nepal.
I guess it is not matching with any Crotalaria.

---

Pl. also check keys and images at

https://sites.google.com/site/efloraofindia/species/a–-l/f/fabaceae/flemingia/flemingia-macrophylla

---

Yes … I already did that and guessed so but could not confirm 100% by myself. May be someone could ID with the help of keys?

---

I will like to go with Flemingia semialata for the time being.

---

You seem to be correct … but I could not find it its listing in the ACFPoN and

latest book from DPR.  All aspects looks closer to Flemingia macrophylla (Willd.) Kuntze ex Merr.

but this plant is very small compared to it and lot of hairs on buds and leaf also thick  and deep veins.

I am still confused between these two.

I further considered your plant.

Checklist of Nepal gives Flemingia semialata Roxb. as a syn. of Flemingia macrophylla as did Catalogue of Life.

However, Flora of Pakistan  GRIN  Tropicos  The Plant List Ver. 1.1  do not think so, as also Floras/ Books of South India.

I finally got online keys in the book at Flora of peninsular India, as per which F. semialata calyx has to be eglandular, which is not the case in your post.
So I take it as F. macrophylla.

---

I think confusion is arising as there are two different Flemingia semialata as per details below from listings in IPNI:

Flemingia semialata Roxb., Pl. Coromandel 3(3): 45 (1820), isonym. Basionym of Maughania semialata (Roxb.) Abeyw., Ceylon J. Sci., Biol. Sci. 2(1): 84 (1959). Isonym of Flemingia semialata Roxb., Hort. Kew., ed. 2 [W.T. Aiton] 4: 349 (1812).

Flemingia semialata Wall., Numer. List [Wallich] n. 5746 G, nom. inval.

Flemingia semialata Roxb., Fl. Ind. (Roxburgh) 3: 340 (1832). Isonym of Flemingia semialata Roxb., Hort. Kew., ed. 2 [W.T. Aiton] 4: 349 (1812).

Flemingia semialata Roxb., Hort. Kew., ed. 2 [W.T. Aiton] 4: 349 (1812). Isonym Flemingia semialata Roxb., Pl. Coromandel 3(3): 45 (1820), isonym. Isonym Flemingia semialata Roxb., Fl. Ind. (Roxburgh) 3: 340 (1832). Replaced synonym of Flemingia paniculata F.Dietr., Nachtr. Vollst. Lex. Gärtn. 3: 390 (1817), nom. illeg.

Flora of Pakistan talks about Flemingia semialata Roxb. ex Aiton, Hort. Kew. ed. 2(4): 349. 1812. Parker, For. Fl. Punj. 3rd, ed. 165. 1956, which is an accepted name.
Checklist of Nepal talks about Flemingia semialata Roxb., Pl. Corom. 3: t. 249 (1815), which is stated to be a syn. of Flemingia macrophylla (Willd.) Merr., ; Philip. J. Sci. 5: 130 (1910).

I think it may be Flemingia prostrata, as posted by … at Flemingia prostrata Roxb.Junior ex Roxb. submission AS2 January 2023 and as per description in Flora of China.
The Description of Flemingia macrophylla looks a bit different as per Flora of China and as per GBIF specimens.

---

May be Flemingia macrophylla only as lower elevation as per Checklist of Nepal and acuminate apex as per description in Flora of China.

---

it should be Flemingia prostrata based on inflorescence which is as long as or shorter than petiole but unfortunately there is no habit image showing its prostrate nature which otherwise makes it easy to confirm species. Flemingia prostrata shows affinities towards Flemingia angustifolia but differs from it in its oblong lanceolate leaflets, inflorescence shorter than the petiole and prostrate habit.

---

To me, inflorescence looks longer than the petiole.
What about lower elevation as per Checklist of Nepal and acuminate apex as per description in Flora of China ?

---

Also POWO and Checklist of Nepal does not show its distribution in Nepal.

---

ILDIS gives the following distribution:
Bangladesh (N) [3091, 3720]; India (N) [3031, 3035, 3091, 3375, 3382, 3598, 3720]; Bihar [3031]; Himachal Pradesh [3598]; Madhaya Pradesh [3375]; Meghalaya [3720]; Punjab [3382]; Tripura [3720]; Uttar Pradesh [3035]; West Bengal [3091]; Myanmar (N) [2110, 3720]; Ryukyu Is (N) [2825]; Taiwan (N)

---

Have you checked Taxonomic revision of the genus Flemingia (Leguminosae: Papilionoideae) in India November 2020 Webbia 75(2):141-218 ?.
This also does not give distribution in Nepal.

---

Yes, this may also be Flemingia prostrata. Kindly confirm or otherwise.

---

you are right

---

 
This year I missed the flower, however I got some images of fruiting stages and enclosing the image .

The sp. I have collected is 90cm. and there could be some taller than this height. The plant is erect, not prostrate.

Compared with the images given in the plates of the article you have sent I feel it is more close to Flemingia angustifolia Roxb.. Please have a look and suggest.
8 high res. images.

---

To me still more closer to Flemingia prostrata.

Also no distribution in Nepal for Flemingia angustifolia.

---

Actually, both the sp. do not have distribution in Nepal and this sp. is  an erect shrub not prostate.

So I am not sure which one is this ?

---

I agree with you that your plant seems more close be F. angustifolia, however I am not sure without inflorescence & flowers details (moreover I am not expert in this genus but perhaps Dr. Manoj Lekhak sir may help with this).

As far as distribution is concerned both both the discussed species are known from adjoining areas of India. So, distribution is not a problem infact the syntype of F. angustifolia are from adjoining areas of Uttar Pradesh state so it may be present in Nepal as well.

Hoping to see inflorescence and flowers images next season!

---

Thank you … By the way I had posted inflorescence images earlier in Sep 2018 in this mail https://groups.google.com/g/indiantreepix/c/QAJ.

This time I was a bit late to collect flowers for dissection and needed to wait for the next season.

Anyway, if you can validate with the images of flowers from the enclosed link ?

---

After comparing all the images in my opinion your plant should be F. prostrata, the branched stems of this species can grow up to 0.5–1 m long.

---

So, branches could be erect for this sp. also ?

---

Yes, few mature branches may be partially erect but generally the plant habit is prostrate. There are no plant habit and habitat images in the post to see how erect and tall plants were in-situ.

Image DSC_0064.JPG clearly shows weak stems and not with upright erect stature.
