differs from Oryza, with which it is combined by Alex. Braun, 
by the entire suppression of the glumes. 
58. Eriachne chinensis, Hance in Ann. Sc. Nat. Par. ser. 4, xv. 228. 
(=E. Hookeri, Munro, ined., in herb. Hook.) 
On the summits of hills, growing in profusion in company with 
Apocopis Wrightii, 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 (Reise nach Ostindien 
u. China, 287) under the name of Aira seminibus hirsutis, aristis 
terminalibus flore longioribus ; and, according to General Munro, 
(Journ. Linn. Soc. vi. 42), a specimen from him exists in Linnzus's 
herbarium marked Aira montana. The species is also found in 
Assam, Tenasserim, and, I believe, in Chittagong.

Syn. Pl. Gram. 116. (=Melica refracta, Roxb. Fl. Ind. i. 327, from 
the character.) 
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 would appear that the South- Chinese species of this genus 
must be reduced. Æ. 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 E. zeylanica, 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. orientalis, Trin., is sometimes quite as spreading, 
the pedicels as long, and the leaves as flat as in E. pilosissima, 
Link; and there is then no charaeter I can detect to distin- 
guish them by, exeept the hairiness or smoothness of the leaves 
and vagine. Mr. Bentham describes the glumelle of E. 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 E. bahiensis; and Nees himself di- 
stinetly states (Pl. Meyen. 206) that they are acute. This, how- 
ever, is probably a variable character; for, except in the blunt
