i have recently collected this liana from gajapati district, south Odisha growing in under the canopy of evergreen trees near stream (900 m above msl). Please help me in ID.
Flowers very small (5 mm in diameter), leaves large, 10 to 14 cm long and 5 to 7 cm broad, petiole 5 cm.
Triclisia macrophylla
Many many thanks … for the identification. I was thinking of menespermaceae, but not sure. Yes the sepals and petals are green.
It is shown as critically endangered as per IUCNRed List (CR) with range in Cameroon; Equatorial Guinea (Bioko); Sierra Leone.
Being so, it may not occur in India in wild.
It is male climber of Tinospora cordifolia Does not matches with images at https://sites.google.com/site/efloraofindia/species/m—z/m/menispermaceae/tinospora/tinospora-cordifolia It is not Tinospora cordifolia, the male flower is quite different
Natsiatum herpeticum, Icacinaceae, , Natsiatum herpeticum_RKC01_20032012: Images not visible now. Natsiatum herpeticum Buch.-Ham. ex Arn. (Family: Icacinaceae) I’ve seen this plant at some places in Arunachal and Assam. The leaves and stems are a little scabrid in texture and hence can be easily recognized.
