Species one ( W. diandra Stapf . ) from India. 



Garnotiella Stapf. Spikelets solitary along the short branches of an elongated 

 panicle, articulate with the pedicels. Empty glumes delicate, nerveless, not 

 keeled, the second mucronate-pointed. Flowering glumes very small, with a 

 long, geniculate and twisted awn from the cleft of the apex. Palea very small. 

 Lodicules wanting. Stamens 2. Habit like Garnotia. 

 Species one [G. philippinensin Stapf.) in the Philippine Islands. 

 Cyathopus Stapf. Spikelets solitary along the branches of an open panicle, 

 articulate on short pedicels, which are thickened and cup-shaped above. Empty 

 glumes 3-nerved, mncronate ; flowering glume somewhat shorter, more delicate, 

 5-nerved (the nerves disappearing below the apex), awnless. Palea hyaline. 

 Lodicules 3 ; stamens 3. 

 Species one (C sikkimensis Stapf.) in Sikkim-Himalaya. 

 Before Zenker a Trin. insert: 



Massia Bal. {MegaJachne Thw. non Steud.). Panicle open; empty glumes 

 lanceolate, subulate-pointed, many nerved; flowering glumes with a stout, termi- 

 nal awn, finally becoming indurated together with the long, two-awned palea. 

 Species one (M. triseta Bal. ) from Ceylon to Tonkin. 

 After Spartina Schreb. add Chauvinia Steud. as a synonym. 

 After Chloris Sw. insert Biatherium Desv. as a synonym. 

 After Monochoete Doell. insert Doellochloa O. K. as a synonym. 

 Before Craspedorachis Benth. insert : 



Willkommia Hack. Spikes densely flowered ; empty glumes flat, not keeled, 

 one-nerved. Flowering glume with pointed, short-haired callus at the base, 

 hyaline, short-awned. Palea somewhat shorter than the flowering glume, 

 obtuse. Lodicules wanting. 

 Species three, in southwestern Africa. 

 Before Tripogon Roth, place : 



Pentarraphis Kiinth. {Polyschisfis Presl.) Spikes or rather groups of spike- 

 lets fascicle-like, consisting of 1-2 spikelets, and 1-3 awn-like, often two-cleft, 

 rudiments of a second or third, loosely arranged on the main axis of the inflo- 

 rescence. Spikelets 3-flowered, the upper flower generally staminate, the lower 

 hermaphrodite, the first empty glume of the spikelet very narrow (in the dried 

 condition), awn-like; in case but one fertile spikelet is present in each group 

 the first empty glume of the same forms, with the 4-5 awn like rudimentary 

 glumes, an apparently lateral fascicle of awns (resembling a deeply 5-cleft 

 glume), when there are two fertile spikelets there is between them a fascicle 

 of 3-4 awn like glumes. The flowering glume is always 3-awned. Low, turf- 

 forming grasses. 



Species two, in Mexico. (See Scribner in Bull. Torr. Bot. Club, 17: 131, 

 plates 107 and 108. ) 



Lepidopironia Rich, is reduced to a synonym of Tetrapogon. 

 Opizia Presl, Hackel amplifies and recharacterizes as follows : 

 Staminate spikelets in 2-5 spikes, like those of section 1 of Bouteloua ; pistillate 

 spikelets in two rows, on short spikes, which are half hidden in the sheaths of 

 the lower leaves, one-flowered ; the first empty ghinie short, the second as large as 

 the flowering glume, the latter 3-clef t, 3-awned ; palea shortly 3-toothed or 2-lobed. 

 Above the fertile flower 1-2 sterile glumes, either 3 or manyawned. Low, 

 creeping grasses. (See Scribner in U. S. Dept. Agr. Div. Agros. Bull. 4: 9, f. 4.) 

 Sect. 1. Euopizia. First enapty glume of the spikelet very small. Flowering 

 glume of the pistillate flower as well as sterile glumes with 3 long awns. O. 

 stolonif era Presl. (Fig. 4.) Mexico.
