take up Savi's. Tte Mexican P. elongatus, H. B. K., which is 

 Presl's genus Nowodworshya (first described and figured by him 

 under the name of JRaspailia), has the pedicels, although claTate 

 as in the rest of the genus, yet less decidedly articulate, thus 

 forming some real connexion with the Agrostese. 



4f. GrAENOTiA, Brongn. {Miquelia, Nees, Berghausia, Eadl.), 

 which sometimes comes near to some forms of Polypogon, has, on 

 the other hand, the spikelets in pairs on the inarticulate branches 

 of the panicle as in Miscanthus, and thus very closely connects 

 Tristeginese with Andropogonese. It has, however, none of the 

 long hairs on the rhachilla so common in Andropogonese, and 

 cannot well be removed far from Arundinella, whilst Miscanthus 

 is too near to Imperata to be rejected from Andropogonese. 

 Garnotia comprises about eight species from East India, China, 

 and Japan. 



5. ARUNDiNELiiAjEaddi, includes Ooldhachia,Tvm.,Acratherum, 

 Link, Thysanachne, Presl, and Brandtia, Kunth. It is the prin- 

 cipal genus of the tribe, and comprises about twenty-four species 

 spread over the tropical regions both of the New and the Old 

 World, but chiefly in Asia. It is generally adopted and fairly 

 characterized, though the habit and especially the inflorescence 

 vary much, the panicle being sometimes long, narrow, and dense, 

 or very large, loose, and spreading, with very numerous small or 

 minute spikelets, whilst in a few species it is short and dense, 

 forming almost an oval head with larger spikelets: The two 

 sections proposed by Nees — MeUosaccharitm, with a small tooth 

 on the flowering glumo on each side of the awn, and AcratTierum, 

 in which the glume is quite entire, tapering into the awn — do not 

 prove to be well defined nor conformable to habit. A. Jiammida, 

 Trin., from Brazil and tropical Africa, has neither the habit nor 

 the character of the genus, but is in every respect a Trichopteryx, 

 with which it was not compared by Nees, Trinius, or Doell, 

 because it was at first only known as Brazilian, and TricJiopteryoc 

 was supposed to be exclusively African. 



6. PH.aiNOSPEEMA, Munro, is a single Chinese species, nearly 

 allied to Arundinella ; but there are three lodicules to the flower 

 and no palea (unless one of the lodicules, although apparently in 

 the same whorl as the others, be really a small palea), and the 

 caryopsis is half exserted from the fruiting glumes as in some 

 species of Sporoholus. Phanosperma glolosa, Munro, is a tall 

 grass with a very large loose panicle, the slender but rigid
