92 COLONEL MUNRO'S MONOCJRAI'II OF TIIK HAMBUSACE.E. 



lliaii is usual in B.tuldu. Arnott, in his MS. notes on Hamilton's ^'rasscs, says that 

 880 lib. Ham., Wall. 502G a, is " Becalm liheedei ;" hut that is certainly not the case in 

 the specimens of that number in Wallich's herbarium in the possession of the Linnean 

 Society. Sonu^ of the specimens of this species from Calcutta arc marked " B. slrieta" 

 and some " B. hiilfolia."

This may possibly be a mountain form of B. tulda ; but it appears to me to be a much 

 smaller plant, with a slender and nearly solid stem. The ligula is more extended, the 

 leaves generally whiter below, and the vaginaj arc never fringed on the margin ; the 

 j);uicity of fertile spiculaj is also remarkable. Griflith's herbarium contains a large 

 number of specimens; but I have scarcely been al)le to find a dozen perfect spicula; 

 amongst them. Wall. Cat. 5030a exhibits a very perfect developed state; 5030b &c 

 are ordinarv forms of B. tulda. Thomson savs that bows are made in Sikkiui from the
