Pachystoma senile, Rchb. f {Apaturia niontana, Lindl. Gen. and Sp. 

 Orch. 131) is given for Nuwara Eliya (Macrae) by Lindley. It is a 

 common Indian plant from the Himalaya to Malabar, and figured 

 {A. Lindleyana) in Wight, Ic. t. 1662. Thwaites mistook Aphyllorchis 

 oion/ana for this. I have seen no Ceylon specimens, nor are there any in 

 Liiidley's Herbarium, but it may occur in the island.
