Please suggest specific id for this Crotalaria, recorded from Gori valley area…

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

Please check for C.humifusa.

To me also it matches with Crotalaria humifusa
(More or less similar description of Crotalaria rotundifolia is not reported in India, Pakistan and China.)

Please compare with kew specimen to conclude ID.

Yes Sir. Crotalaria prostrata Wild is an accepted name as per ‘the plant list’.

I think does not match with images at Crotalaria prostrata

Pl. check with images at Crotalaria filipes

I guess it is not matching according to leaves also.

Besides, it is not listed in Nepal.
Request for further opinion.

I will go with Crotalaria humifusa Benth.

Sprawling Rattle pod is found from Himalayas from Kumaon to Sikkim at  altitude of 1800 -1900 m. As per the information provided the specimen was recorded in Sikkim at altitude of 4600 ft (1402 m).

Crotalaria humifusa Benth.

I get some confusion. Legumes are alternate whereas net images showing single legumes at nodes for both C.prostrata and C. humifusa.

Also CoL showing 4 C. prostrata but POWO and GBIF only one.

I am not clear what are you saying. Pl. also give the links.

My post showing 2 opposite legumes at one node nut net images showing 
single legume at one node. Also CoL showing 4sp. of C. prostrata but POWO and GBIF only one.

Yours also show only one legume except at one point. Pl. see your 6th image.

OK …!

Attached images are Desmodium sp. – 1 from Meghalaya. Please ID the plant

This may be Crotalaria prostrata

Leaf is stipulate, therefore unlikely to be C. prostrata.

I think lose to images at Crotalaria humifusa Benth.
