Appears as a species of Agrostemma (Rubiaceae). (But where are stamens?).
Thanks … for the input, no exserted stamens were seen in any of the specimens observed…
and perhaps you wanted to say “Argostemma” instead of “Agrostemma“
Perhaps this picture can help, not a clear view but this shows exserted stamens ..
To me too it looks A.sarmentosum. Attaching an old pic taken near Jeolikot on way to Naini Tal.
Thanks … for confirming the identification as Argostemma sarmentosum

I need id assistance for following species collected from Darjeeling
Argostemma sarmentosum Wall. (Rubiaceae) to me. Often along streams on moss covered shady slopes.
Many many Thanks … for your id assistance.
Could this be a species of Argostemma???
Yes Argostemma courtallense Arn. of Rubiaceae family.
Yes … you are right
This appears to be Argostemma sarmentosum Wall., as Argostemma courtallense Arn. does not have distribution in the area.
Yes, I too agree with Argostemma.
