Upper part of Samarahan river basin

First time found Barclaya kunstleri (Nymphaeaceae) in the hardwater river near limestone outcrop.....

Barclaya kunstleri (Nymphaeaceae) grows on the submerged tree roots to prevent the strong water current to pull it up.....

Probably  Pterocheras sp.(orchid) - it fell down into riverbed.

Homalomena sp.

Piptospatha viridistigma
