centia with Cladium; and remarks that Gahnia (to which he re- 
duces .Lampocarya) differs rather in habit than structural cha- 
racters. 
*Arthrostylis chinensis, Benth. 
Glumes distichously imbricate, pale brown. Bracts usually 
shorter than the spikelets. Hypogynous bristles often present, 
and longer than the nut. Style long, 3-cleft at the apex, dark- 
coloured, very gradually thickened towards the base, and there 
separating at maturity. Nut white, trigonous, with three finely 
granulated raised bands running down the angles from the apex; 
the faces between marked with blunt protuberances so as to look 
like shagrcen leather. Except that the style is articulated with 
the achene and falls off entirely, instead of leaving a more or 
less conspicuous persistent base, there is absolutely nothing to 
distinguish this genus from Schenus, with which it entirely agrees 
in habit; and I have proposed their being united. (Seem. Journ. 
Bot. vii. 63.) 
*Scleria radula, Hance in Ann. Sc. Nat. Par. ser. 4, xviii. 232. (=S. 
levis, Retz., var. scaberrima, Benth. Fl. Hongk. 400.) 
Appears to me abundantly distinguished by many marked cha- 
racters.

purpurascens, Benth. FI. Hongk. 400, but not of Steudel.)

According to Prof. Grisebach (Fl. Br. W. Ind. 547), this is 
identical with P. molle, Sw., an obscure species. Spruce’s Barra 
plant, distributed under the name of P. Meyerianum, Nees, and 
also referred here by Grisebach, seems to me quite different ; but 
whether it be the same as the Kaffrarian grass (Fl. Afr. Austral. 
32), I do not know.
