Fournier also was not aware of the Chilian species previously 

 published by Philippi, whose generic name necessarily takes the 

 precedence over Fournier's. 



10. Eeemochloa, S. Wats., contains two New-Mexican or 

 Californian species, well described and illustrated by S. Watson. 

 The genus is exceptional in the subtribe in its one-flowered 

 spikelets, and in the two empty three-awned glumes between 

 the lower pair and the flowering one. 



11. Teieaphis, Br., comprises five or six species, one as yet 

 unpublished from South Africa, the others from Australia. In 

 all, the three lobes of the flowering glumes are awned, whilst in 

 one species, T. mollis, Br., otherwise inseparable from the genus, 

 there are additional small membranous lobes between the awns, 

 and at least five nerves to the glume, showing a close connection 

 with the Pappophoreae. T. microdon, Benth., from Australia, is 

 a very anomalous plant with unawned glumes, which should be 

 removed from the genus ; but it is diiflcult to say where it should be 

 placed T. capensis, Nees, is a Danihonia {D. radicans, Stead.). 



The third subtribe, Arundinece, though often regarded as a 

 substantive tribe, has no definite character beyond the tall habit 

 with a rich panicle, as designated by the common name Meed, 

 and the long hairs surrounding the flowering glumes, either 

 arising from the rhachilla or from the glumes themselves. This 

 character, however, is no more exclusive here than in Saccharese ; 

 for there are other genera, such as Oalamagrostis, Qraphephorum, 

 &c., which have the hairs nearly as long, but which on other 

 accounts cannot be included in Arundinese. The genera certainly 

 belonging to the subtribe are four : — 12. Gyneeittm, Humb. 

 and Bonpl., three tropical or subtropical American species with 

 strictly dioecious spikelets. 13. Ampelodbsmos, Beauv., two 

 Mediterranean species with rigid five-nerved flowering glumes. 

 14. AEirNDO, Linn. {Donax, Beauv., Scolochloa, Mert. and Koch, 

 Amphidonax, Nees), three or four species from the warmer 

 regions of the New and the Old "World, very abundant all round 

 the Mediterranean, with three-nerved flowering glumes ; and 15. 

 Pheagiiites, Trin. {Arundo, Beauv., Czernya, Presl, Trichodon, 

 B-oth), two species, one of them almost cosmopolitan, only differ- 

 ing from Arimdo in the lowest flower of the spikelet being male 

 only. These last three genera are frequently, and perhaps with 

 reason, regarded as sections only of Arundo. Two Mexican 

 monotypic genera proposed by Fournier, 16. Gotjinta, and 17.
