Apocynaceae member, Ceropegia sp.,


What are the species reported from your area?


Ceropegia angustifolia, C.longifolia and C.macrantha are recorded in Mizoram


Maybe some other genus.
Does not match with any of these species as per Ceropegia macranthaCeropegia longifolia and Research Gate


I guess this is not Ceropegia sp.


Probably genus Brachystelma


Thanks, … Yes, it appears to be. Could you pl. help us in the id of this one?
Hi, …, What are the species reported from your area?
I tried, but could not reach to any conclusion as per

The genus Brachystelma is not recorded in Mizoram


Anything from Frerea or related genus?


No, nothing sir


Do you have any other photos like that of roots etc.?


Sorry ! No, sir


without detailed photos of this specimen, we cannot go more further on the Identification


Thanks, … But are sure that it is Brachystelma ?


Whether this is tuberous herb?
More photos with closeup will be essential.

At present it doesn’t look like Brachystelma.


Corona in the image is not visible and the tuber is present or not. Corona whether single or double. If it is double, then it is Brachystelma


Brachystelma sps


Convallariaceae ??


An Apocynaceae I believe, Pentasachme caudatum.


Yes …  is right. Its Pentasachme caudatum Wall. ex Wight (Apocynaceae) distributed from Nepal to East Himalaya and much of SE Asia.


I think … got it right! Great work …!
