Reduced by Hackel to a section of Setaria. 



After Scfariopsis add: 



Ixophorus Schlecht. (fig. 3), which Bentham and Hackel formerly placed with 

 Setaria, is a well-defined genus. Characters: Spikelets 3 flowered, the upper 

 flower hermaphrodite, the lower staminate, arranged in two rows along the 

 branches of a simple panicle, their pedicels provided wath a smooth, sticky, awn- 

 like bristle {chcetodadium). First empty glume very short; second somewhat 

 shorter than the third ; the latter o-nerved, much longer than the flowering glume 

 of the hermaphrodite flower, which is awn-pointed. The palea of the staminate 

 flower (in the axis of the third glume) has at maturity two broad, parchment- 

 like wings, determining the form of the spikelet. Very different from Chteto- 

 chloa in inflorescence, approaching in this respect the section Ptychoiihyllum of 

 Panicnm. Tlie viscid secretions on the bristles are worthy of notice. 



Species two, in Mexico. 



After Ixophorus add: Dissochondrus (Hillebr. as subgenus) O. Kuntze. Like 

 Cha^tochloa, but both flowers hermaphrodite with coriaceous, persistent flower- 

 ing glumes and palea ; the leaf -blades attenuate below, the mouth or throat of 

 the sheath with two lon^, narrowly -lanceolate lobes. 



Species one (D. biflorus O. Kuntze) in the Sandwich Islands. 



The synonym Oxyanthe Steud., under Pennisetum, probably belongs to Arnndo. 



Under Oryza add: Bhynchnryza Baill., founded on Oryza snbulata Nees (from 

 Brazil), differs from Oryza only in the flowering glumes being lengthened into 

 a hollow beak, articulated by separation-membranes (instead of a deciduous awn) 

 and in the united lodicules. It might better be regarded as a subgenus of Oryza. 



After Piptocho^tium Presl, add as a synonym Caryochloa Spreng. 



The genus Brachyelytrum, through recent discoveries, has undergone an exten- 

 sion and is now be divided into three subgenera, as follows : 



Sect. 1. Aphanelytrum Hack. Empty glumes diminutive, scarcely 0.5 mm. 

 long, often wanting. Flowering glumes subhyaline with short, subulate awn. 



Species one {B. procxnnhens Hack.) Ecuador. 



Sect. 3. Eubrachyelytrum Hack. Empty glumes short, firm in texture, the 

 upper about one-eighth the length of the flowering, which is long awned. 



Species one {B. aristatum Beauv.), North America. 



Sect. 3. PsevdobromusK. Schum. as a genus. Empty glumes from one-half to 

 two-thirds the length of the flowering glume, which is long-awned, firm, herba- 

 ceous. 



Species two, in Africa: B. Africanum Hack., in Transvaal and B. silvaticum 

 (K. Schum.) Hack., in Kilimandscharo. 



After C'rypsis Ait. add as a synonym PaUasia Scop. 



Chaboissaea Fourn., Mex. PI. Enum., Gram. 112. 1886. Spikelets in narrow 

 panicles, 2-flowered, the lower flower hermaphrodite, the upper imperfect; 

 empty glumes unequal ; flowering glumes mucronate-pointed and ciliate on the 

 margins ; stamens 3 ; styles long ; stigmas phimose. 



Species one in Mexico. Allied to Middcubergia. 



Before Mibora Adans. insert Brousmichea Bal. False spike cylindrical ; empty 

 glumes solitary and united below at the margins for one-third to two-thirds their 

 lengtli. Flowering glume awnless, 1-nerved; palea nerveless. Lodicules none. 

 With the aspect of Sesleria. 



Species one {B. seslerioides Bal.) in Tonkin. 



After Garnotia insert the three following genera : 



Woodrovia Stapf. (Hook. Icon, PI. 5: P1.2U7. 1896). Spikelets in slender 

 racemes which are subdigitately panicled; empty glumes compressed, 1-nerved 

 with a rounded, thickened keel, the first much exceeding the 2-lobed flowering 

 glume which bears a slender, geniculate awn between the lobes; stamens 2. 

 Annual.
