THE FLOEA HONGKOKGENSIS. 45 



centia with Cladimn ; and remarks that Oahnia (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 shagreen leather. Except that the style is articulated ^ith 

 the achene and falls off entirely, instead of leaving a more or 

 less conspicuous persistent base, there is absolutely nothing to 

 distinguish this genus &om Schmnus, with which it entirely agrees 

 in habit ; and I have proposed their being united. (Seem. Joum. 

 Bot. vii. 63.) 



*Scleria reulula, Hance in Ann. Sc. Nat. Par. ser. 4, xviii. 232, (=S. 

 Isevis, Retz., var. scaberrima, Benth. Fl. Hongk. 400.) 

 Appears to me abundantly distinguished by many marked cha- 

 racters. 



♦Scleria Haxlandi, Hance in Ann. Sc. Nat. Par. ser. 5, v. 248. ( = Scleria 

 piirpurascens, Benth. Fl. Honglc. 400, but not of Steudel.) 



*Faiucuin sarmentosum, Rosob. 



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. Meyerianwm, 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. 



49. Panicum (Echinochloa) stagninum, JSjsb. ; Miq. Fl. Ind. Bat. iii. 



464. 

 In stagnant water. Diffused over India, Southern Asia, and 



North-eastern Africa. 



50. Gaxnotia drymeia, Hance in Ann. Sc. Nat. Par. ser. 4, xviii. 233. 

 In moist shady woods. Occurs also on the adjacent continent, 



but is not known from elsewhere.
