Sharing the images of Calamus thwaitesii from NBNP.
Location: NBNP Garden
Habit: Wood slimber.
Thanks for sharing the pictures. Can you send a photograph of the whole plant.
Are you confident about the identification of this species?
I feel this species something different from Calamus thwaitesii.
It is also feels like Calamus pseudotenuis.
You please send one fruit photo for confirmation if possible
Please note two more points:
1. The edges of leaf show any narrow projections?
2. The tender leaf show yellowish or red tinge?
Possibly Calamus nagbettai (not C. thwaietsii nor C. pseudotenuis)
