pedicel, and the very different shape and proportion of the glumes, 

 seem sufficient to maintain the genus as distinct. 



8. LoPHOLEPis, Dene., is a little slender East-Indian annual, 

 allied in some respects to Latipes, hut with excessively minute 

 curiously shaped spikelets, so rapidly ripening and so very deci- 

 duous that it is very rare to find any on the specimens in an 

 examinable state. The plant was first sent home by "Wallich 

 under the name of Solhoellia, and was figured as such by Hooker 

 in the Botanical Magazine ; but in the meantime "Wallich pub- 

 lished a Lardizabalous genus under that name in his Tentamen 

 of a Nepal Flora, and Decaisne therefore changed that of the 

 present grass to LopJiolepis. 



9. Netikachne, R. Br., three Australian species, and 10. Peko- 

 Tis, Ait. {Xystidium, Trin.), from the tropical regions of the Old 

 World, of which the species are variously estimated as from two to 

 seven, are both of them well-known genera, accurately described 

 and figured. 



11. Leptotheium, Kunth, founded on a specimen brought by 

 Humboldt from tropical America, is unknown to me. It is said 

 to be very near the Asiatic genus Zoysia, and, from the descrip- 

 tion, seems to differ chiefly in its widely distant geographical 

 station and in the presence of an additional lower empty glume. 



12. ZoTSiA, Willd. {Matrella, Pers.), is a well-defined genus of 

 two or three maritime plants, dispersed over the shores of eastern 

 and southern Asia, Australia, and New Zealand, extending also to 

 the Mascarene Islands. 



To these Zoysieee I have provisionally added a small Mexican 

 plant, the affinities of which are very puzzling, and which I 

 have described and figured as a new genus ScHAirifEBA, so named 

 after the collector from whom we have received it. At first sight 

 it seemed to bear some resemblance to Presl's figure of Gatheste- 

 chus ; but the structure of the spikelets is quite different, being 

 nearly that of Zoysia, whilst the general inflorescence, though on 

 a much smaller scale, approaches that of some species of Andro- 

 pogon {Cymbopogon) or of Apluda. 



Tribe VI. AifDBOPOQONEiE. 



This tribe is chiefly characterized by the spikelets in pairs at 

 each node of the articulate rhachis of the spike or of the branches 

 of the panicle, or in triplets at the end of each branch, and by 

 the inner glume under the fertile flower being much smaller and
