1. SCHIZOSTACHYUM Xccs. 



Spikelets slender, cylindric ; glumes narrow, usually mucronate ; lemmas 2 to 3. the 

 lower I or 2 sterile and like the glumes in ap])earance, the fertile i or 2, much imbricate and 

 convolute : palea similar to the lemma, convolute, not keeled ; rachilla prolonged and bearing 

 a rudimentary floret : lodiculcs usually 3, narrow, lanceolate, ciliolate ; stamens Ti ; ovary 

 narrow, with a long style and 3 stigmas ; caryo]5sis ovoid, beaked, inclosed in a crustaceous 

 separate pericarp. Arl)orc.sccnt or slirubby usually erect bamlxios with panicles of .spicate 

 branches, bearing heads (jf s])ikelcts, in some s])ecies reduced to a spike of heads.

Culms erect, as much as 6 cm. thick at base, the culm-sheatiis 10 cm. broad: foliage- 

 blades linear-oblong, as much as 30 cm. long and 3.5 cm. wide, rather abruptly contracted at 

 tile base into a petiole about 5 mm. long, narrowed at apex to a fine involute point, glabrous, f)r 

 .scaberulous on the upper surface near the apex, the margin glabrous or scabrous, the midrib 

 whitish and rather prominent below, the primary veins about 10 pairs; sheaths glabrous, the 

 throat glabrous : ligule a short firm ridge less than I mm. long, slightly ciliate : inflorescence on 

 clusters of slender branches from the nodes; spikelets in heads, spicate or paniculate along the 

 branches, the heads about 2 cm. in diameter, in many specimens contiguous, the whole branch 

 30 to 40 cm. long; spikelets fusiform-cylindric, about i cm. long, pale, tawny or stramineous, 



2 or 3 in the axils of bracts, the bracts similar to the glumes hut longer. 



The three .specimens cited ai"e floriferous hut the .siiikelels are all sterile and 

 show no stamens (jr pistils. They may not he correctly referred to .V. glaucifolium 

 but are the same as Munro's specimen. Munro' remarks tlial the specimen exam- 

 ined by him, this or a duplicate being in the Gray Herbarium (T;iliiti, Wilkes 

 Ivxped.), was in the same condition. 'Phe spikelets are sessile, 2 or 3 together, 

 bearing 4 bracts, each successively longer, tlie first 3 similar, convohtte, nerved, 

 mucronate, the fourth very slender, tiglitly mlled ;nid nuicli convuliile. 'I'here 

 appears to be no pnilongation of the rachilla.
