68. Eriachne chinensis, Hance in Ann. Sc. Nat. Par. ser. 4, xv. 228. 

 (=E. Hookeri, Munro, ined., in herb. HooJc.) 

 On the summits of hills, growing in profusion in compaaiy with 

 Apocopis WrigUii, Munro, but very local. This elegant grass is 

 very.abundant at Whampoa, where it was first discovered in Sep- 

 tember 1751 by Osbeck, who mentions it (Eeise nach Ostindien 

 u. China, 287) under the name of Aira semimibus hirsutis, aristis 

 terminalihus flore longioribus ; and, according to General Munro, 

 (Journ. Linn. 8oc. vi. 42), a specimen from him exists in Linnseus's 

 herbarium marked Ai/ra montana. The species is also found in 

 Assam, Tenasserim, and, I believe, in Chittagong.

 Not uncommon in damp woods and shaded ditches. Widely 

 spread over continental and insular India, the Malayan archipe- 

 lago, Philippines, Australia, and the Pacific islands.

 It w^ould appear that the South- Chinese species of this genus 

 must be reduced. ^. geniculata, Nees, is the most distinct- 

 looking of all, from its compact spiciform inflorescence ; but this 

 occasionally breaks up into separate branches, and it is then not 

 always possible to distinguish it from H. eeylanica, Nees, in its 

 normal state as unlike as can be, but of which depauperate spe- • 

 cimens with approximate and abbreviated panicle-branches show 

 at once how easy is the transition between the two. Again, the 

 panicle of E. orientaHs, Trin., is sometimes quit© as spreading, 

 the pedicels as long, and the leaves as flat as in M pilosissima. 

 Link ; and there is then no character I can detect to distin- 

 guish them by, except the hairiness or smoothness of the leaves 

 and vaginse. Mr. Bentham describes the glumellse of M orien- 

 talis as "very obtuse;" but in a specimen determined by Ge- 

 neral Munro, as well as in all others I have examined, I find 

 them more acute than in JE. bahiensis ; and Neea himself di- 

 stinctly states (PI. Meyen. 206) that they are acute. Tbis, how- 

 ever, is probably a variable character ; for, except iu the blunt
