422 gramineje. [Apocopis. 



the top, with a narrow reddish ciliate margin, closely imbricate and usually 

 concealing the remainder of the spikelet as well as the hairs at its base, and the 

 rudimentary hairy pedicel. Awns protruding to 5 or 6 lines in the upper spike- 

 lets, but very deciduous, and often deficient in the lower part of the spike. 

 Hongkong, on the Syagmoon channel, Wright ; also in Borneo. 



24. APLTJDA, Linn. 



Spikelets with 1 fertile and 1 male flower, sessile between 2 flattened 

 pedicels, bearing each a rudimentary glume or one of them a perfect spikelet, 

 the whole embraced by a sheathing bract, the bracts clustered on the branches 

 of a leafy panicle. Lowest glume of the sessile spikelet concave and striate, 

 the second keeled, transparent, but stiff ; flowering glumes very thin and trans- 

 parent, the terminal one often awned. In the pedicellate flower both the 

 glumes concave and striate. 



A genus of 2 or 3 species from tropical Asia or Africa. 



I. A. mutica, Linn.; Kunth, Enum. i. 516. Stem creeping or climbing, 

 several feet long, with erect branching flowering shoots. Leaves long, some- 

 what distichous. Panicles loose and leafy, 1 to 2 ft. long. Flowering bracts 

 3 or 4 lines long, very concave, with short sometimes awn-like points, in 

 clusters of 5 or 6. Sessile spikelet shorter than the bract ; pedicellate spike- 

 lets, when present, protruding beyond it. Awns of the flowering glume very 

 minute or entirely deficient. 



Hongkong, Hance, Wright. Common in the Indian Archipelago, extending northward 

 to Amoy, and to the eastern districts of India, hut less common there than the A. aristata, 



25. ANDROPOGON, Linn. 

 Spikelets 1 -flowered, in pairs, 1 sessile, the other pedicellate, in a simple 

 spike or along the spike-like branches of a simple or compound panicle, the 

 rhachis articulate at each pair, and at the terminal article 2 pedicellate spike- 

 lets, one on each side of the sessile one. Sessile spikelet hermaphrodite, the 

 lowest glume stiff, with 2 of the lateral nerves most prominent, the second 

 keeled, third empty glume very thin and transparent ; flowering glume small 

 and transparent, with a long twisted awn. Palea very small and thin or none. 

 Pedicellate spikelet smaller, male only, or reduced to a single glume. Grain 

 free, enclosed in the outer glumes. 



A large genus, widely distributed over the globe within the tropics, with a few species ex- 

 tending into more temperate regions, both in the northern and the southern hemispheres. 

 Spikes single and solitary {Schizachyrium) . 



Spike full 2 in. long. Rudimentary spikelet on a flat pedicel, with a 



point shorter than itself 1. A. zeylanicm. 



Spike not 1 in. long. Rudimentary spikelet on a narrow pedicel, with 



an awn longer than itself 2. A. brevifolius. 



Spikes pedunculate, in a loose or compound panicle. 

 Panicle without bracts (Amphilophis). 



Outer glumes narrow-oblong, rather thin. Hairs of the pedicels 

 short and pale. 



Spikes not i in. long, with 2 or 3 articulations 3. A. montanus. 



Spikes 1 to near 2 in. long, with numerous articulations . . . 4. A. Vachellii. 

 Outer glumes ovate-oblong, hard. Hairs of the pedicels very con- 

 spicuous, of a rich brown . . . . ; 5. A. tropicus. 



Panicle with a leafy bract at most of the ramifications (Cyml/opogon) 6. A. Martini.
