material that Grisebach worked upon. He also describes gl. IV as ellipsoid, but it is 

 ovate-lanceolate in both. Whether P. sulcatum is specifically different may be 

 doubted. P. excurrens, Trin., is a small narrow -leaved flaccid (perhaps young) 

 state, with a very slender panicle and erect branches; it is Wall. Cat. n. 8703, and 

 a common Himalayan form. Wall. Cat. n. 8705 is a gigantic form from Silhet, 

 where I found it abundantly.
