Oldenlandia/ Borreria SN 910121: 2 images.
Wild herb from Orissa Sal forest.
Oldenlandia pinifolia
Spermacoce pusilla Wall. (= Borreria pusilla (Wall.) DC.)
I agree with …
Oh my god, No way …, it’s not Spermacoce pusilla,
It’s Oldenlandia only because Spermacoce pusilla have much flowered sessile clusters at axillary and terminal,
In this, there is clear pedicellated 1 or 2 flowers at node,
OK … ! I thought it has got no distribution in Orissa !
