Dear Rathinaji, 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?
