Spodiopogon."] CLXXIII. GRAMINE^J. (J. D. Hooker.) 109 



Garwhal, Jacquemont, Duthie. KHASIA HILLS, alt. 3-4000 ft., J. D.H. 8f~T. T. 

 DISTRIB. China, Japan. 



Perennial. Stem 3-8 ft. or more from a woody branched stock, as thick as a 

 swan's quill or less. Leaves 2-3 ft. by ^-f in. ; sheath long, grooved; ligule short. 

 Panicle 6-12 in., rachis slender, terete, branches whorl ed, capillary, lower 1-3 in., 

 lax-fld., flowering towards the ends ; pedicels T y- in., clavellate, tips cupped. Spike- 

 lets | in., green; tall callus bearded; gl. I and II very strongly 7-9-nerved, nerves 

 scaberulous, tips 2-dentate and very shortly awned ; III oblong, tip rounded, 

 scaberulous above the middle, not ciliate ; palea lanceolate, subciliate ; IV glabrous, 

 cleft to below the middle into setiform lobes, awn twice as long as the spikelet ; palea 

 large, broadly ovate, obtuse, ciliate, nerveless. A peculiar grass very unlike the 

 other species.

Annual or perennial grasses. Spikes subdigitately approximate or 

 fascicled, hirsute silky or ciliate, rachis fragile. Spikelets binate a sessile 

 and pedicelled rarely both pedicelled, 1-fld. or the sessile 2-fld. Glumes 

 4, I membranous or coriaceous, dorsally flattened or concave, truncate 

 often narrowly, or tip 2-toothed, margins narrowly inflexed throughout its 

 length ; II as long, usually laterally compressed, keeled, acute, rarely 

 awned; III hyaline, ciliate, rarely neuter or male, paleate (sometimes 

 represented by a gl.-like palea) ; IV very short, hyaline, entire 2-fid or 2- 

 auricled or reduced to a idilated base of the long twisted exserted awn ; 

 palea small or 0. Lodicules obliquely truncate. Stamens 3, rarely 2. 

 Stigmas long. Grain free. Species about 30, tropical and subtropical of 

 the Old World. 



The characters by which Pollinia is distinguished from Isckcemum are very un- 

 satisfactory. The colour of the hairs of the spikes in Sect. Eulalia cannot be 

 altogether depended upon ; nor can the sexuality of the spikelets and presence or 

 absence of gl. Ill be in Sect. Leptatherum. The apparent replacement of gl. Ill in 

 some species by a palea as long as gl. I and concave towards it, first observed and 

 commented on by Hackel (Androp. 171) is a very curious departure from the normal 

 condition of the spikelet in Andropogonece. It is n6t confined to Pollinia. 



Sect. I. Stem erect. Leaves not conspicuously constricted or petioled 

 above the sheath. Gl. I as long as II, narrowly truncate ; II not broadly 

 truncate ; III or its palea present. 



* Glume II of sessile spikelets awned. Basal sheaths of stem naked. 



1. P. articulata, Trin. in Bull. Sc. Acad. Petersb. (1836) 71 ; annual, 

 very slender, . leaves usually filiform, spikes usually very many, hairs of 

 rachis white, spikelets -ra-ro in. brown, gl. I narrowly truncate, keels villous 

 below with white hairs, II glabrous except the margins, III (P palea of 

 gl. IV) ovate obtuse, IV narrowly oblong 2-fid or 2-toothed, awn very long 

 ciliate, palea short broad. Hack. Monogr. Androp. 153 ; Benth. Fl. Hongk.
