Flora of Chakrata 2013:: One More Stone Flower.. : Attachments (4 + 1 + 1).  5 posts by 2 authors.
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

Perhaps this picture can help, not a clear view but this shows exserted stamens ..
thanks … for helping, so this can be Argostemma sarmentosum
