Saccharum.'] CLXXIII. GRAMINEJJ. (J. D. Hooker.) 121 



lanceolate spikelets, gl. I 2-toothed keels minutely spinulous, III and IT 

 pectinately ciliate with very long hairs. 



MALAY PENINSULA j Pahang, Ridley. 



Stem several feet high. Leaves 2-3 ft. by |-J in., linear, rigid, green, glabrous, 

 margins scabrid ; sheath terete, glabrous ; ligule very short, truncate. Panicle 

 2 ft. long, erect ; rachis angular, subgeniculate at the distant bearded nodes ; 

 branches fascicled, very long, filiform ; spike 3 -5 in., firm, flexuous, lax-fld., glabrous 

 except the bearded axils ; joints and pedicels slender, glabrous, terete. Spikelets 

 both pedicelled equal and perfect, in. long, yellowish-brown ; pedicel of lower = 

 the length of the upper which is about i shorter than the joint ; gl. I chartaceous, 

 dorsally flat, sides incurved and base sparsely hairy, 2-3-nerved besides the keels ; 

 II chartaceous, acute, 3-nerved, sparsely hairy ; III nearly equal II, nerveless, margins 

 incurved the long hairs crossing ; IV rather shorter, broadly ovate, nerveless, its 

 long hairs up-curved 9 palea variable, small or minute, ciliate. 



DOUBTFUL SPECIES. 



S. BEUNNEUM, Desv. Opusc. 65, is a species of Tricholaena, according to Hackel 

 (Monogr. in Index, p. 707), but as that genus is suppressed and the only Indian plant 

 referred to it is S. fuscum (q. v.), it follows that S. brunneum may be that plant, 

 and if so Lesvaux's name has priority. 



36. ER1ANTHUS, Michx. 



Habit and characters of Saccharum, but gl. IV awned, rarely awnless. 

 Species about 16, temperate and tropical. 



I find no characters whereby to distinguish Erianthus from Saccharum except 

 that given above, which is all but illusory, and a re-examination of both genera may 

 lead to a better disposition of their species under two or more genera or sections. 

 Pollinia differs chiefly in the digitate spikes (see JE.fastigiatus). 



A. Lower branches of the panicle much shorter than the rachis. 



* Panicle decompound ; ultimate branchlets (spikes) very short, of 3-4 

 joints ; awn of gl. IY short or obsolete. 



1. E. Ravennae, Beauv. Agrost. 14 ; leaves flat, ligule very short, 

 panicle oblong, hairs of callus as long as the gls., spikelets \-\ in. 

 linear-lanceolate, gl. I membranous lanceolate acuminate tip 2-mu- 

 cronate keels subspinulosely scabrid, IV rather shorter than I ovate- 

 lanceolate narrowed into a slender awn of its own length or shorter.
