This white flowered herb was also found growing on rocks in Chakrata area.. I could get this identified..
help requested..

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“

---

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

Many many Thanks … for your id assistance.

This appears to be Argostemma sarmentosum Wall., as Argostemma courtallense Arn. does not have distribution in the area.

---

Agree

Yes, I too agree with Argostemma.
