In I\ew Library is a copy of a drawing of P. insectifera Ridl. (Sarcanthus 
insectifera Hook, fil.), an Indian plant, said to be made from a plant collected 
in Perak by Kunstler, which flowered in the Calcutta Gardens. It is possible 
that the plant may occur in the Peninsula, but I am unwilling to incorporate 
it without further evidence. It has small flowers with a pink lip.
