 Benth. Fl. Hongk. 418.) 

 I consider this is truly distinct from the Ceylon and South- 

 African P. hordeiformis, Nees, by its much longer spikelets an4 

 awns, and looser racemes. Steudel'giTes. seven species oiPerotis ; 

 but I believe the two just mentioned and P. rara, E. Br., are the 

 only well-founded ones. 



•Zoysia sinica., Hance in Seem. Journ. Bot. vii. 167. (= Zoygia pun- 

 gens, Benth. Fl. Hongk. 418.) 

 I consider this a very good species as compared with the true 

 Z. pungens, Willd., &om Ceylon and Australia.

In waste places, on a dry gravelly or sandy soil, but not 

 common. Occurs on the mainland, near Canton, and also in 

 Bengal.

 On bank-sides, but not a common grass in Hongkong. Abun- 

 dant in many places on the adjacent mainland, and extending up 

 the coast of China as far as Japan ; occurs also iu the mountainous 

 regions of India. The group to which this ppetty grass belongs 

 seems to me a natural one, all the species having a very marked 

 inflorescence ; but Grisebach, following Trinius (Gottinger Nach- - 

 richten, !Febr. 1868, 90), combines it with Andropogon. The pre- 

 sent, species varies a good deal in the number of spikes, the size, 

 colour, and smoothness or roughness of the glumes, and absence 

 or length when present, of the awns of the florets, and has been 

 much misunderstood, as the above list of synonyms, which might 

 doubtless be extended, will show. A. nudum, Wall. {Pleuroplitis 

 cenirasiatica,GnBeh.), whichis found in the Himalayas, Nipal, and 

 the Songorian steppes, is very doubtfully distinct ; and the two are 

 combined by Eegel (Trautvetter, Enum. PI. Schrenk., contin. 4!. 

 71). See the observations of Grisebach (Ledeb. M. Eoss. iv. 478).
