Hitchcock — The Grasses of Haicaii i6i 



loosely inclosed in the thin pericarp. Annual grasses with two to several rather stout spikes, 

 digitate at the summit of the culms, some plants with one or two spikes a short distance below, or 

 rarely with a single terminal spike (fig. 48).

Plants very smooth : culms flattened, decumbent at base or prostrate-spreading ; sheaths 

 loose, overlapping, compressed: spikes 2 to 10, 3 to 7 cm. long; spikelets appressed, 3 to 5-flow- 

 ered, about 5 mm. long (fig. 48).

25. DACTYLOCTENIUM Willd. 



Spikelets 3 to 5-flowered, compressed, sessile and closely imbricate, in two rows along 

 one side of the rather narrow flat rachis, the end projecting in a point beyond the spikelets; 

 rachilla disarticulating above the first glume and between the florets ; glumes somewhat unequal, 

 broad, i-nerved, the first persistent upon the rachis, the second mucronate or short-awned below 

 the tip, deciduous : lemmas firm, broad, keeled, acuminate or short-awned, 3-nerved, the lateral 

 nerves indistinct, the upper floret reduced ; palea about as long as the lemma ; seed subglobose, 

 ridged or wrinkled, inclosed in a thin, early-disappearing pericarp. Annual or perennial grasses, 

 with flat blades and two to several short thick spikes, digitate and widely spreading at the 

 summit of the culms. 



I. Dactyloctenium aegyptium (L.l Richt. PI. Eur. 1:68. iSgo. 



CynosKnis aegyf^tius L. Sp. PI. /2. 1753. 



Culms ascending or prostrate, 10 to 30 cm. long; blades flat, mostly less than 10 cm. long 

 and 4 mm. wide, more or less ciliate at base ; spikes 2 to 5, i to 3 cm. long, rather thick, densely 

 flowered; spikelets pectinate, 3 mm. long; palea winged on the keels (fig. 49). 



A weed along streets; introduced. Originally described from "Africa, 

 Asia, America."

26. CAPRIOLA Adans. 



Spikelets i -flowered, awnless, sessile in two rows along one side of a slender continuous 

 raohis, the rachilla disarticulating above the glumes and prolonged behind the palea as a slender 

 naked bristle, this sometimes bearing a rudimentary lemma; glumes narrow, acuminate, i-nerved, 

 about equal, shorter than the floret; lemma strongly compressed, pubescent on the keel, firm in 

 texture, 3-nerved, the lateral nerves close to the margins. Perennial, usually low, grasses, with 

 creeping stolons or rhizomes, short blades, and several slender spikes digitate at the summit of 

 the upright flowering culms.

Culms flattened, wiry, glabrous; ligule a conspicuous ring of white hairs; spikes 4 or 5, 

 3 to 6 cm. long; spikelets imbricate, 2mm. long, the lemma longer than the glumes (fig. 50).
