148 CLXXIII. GIUMINEJ:. (J. D. Hooker.) [Isc/mochloa. 



with thickened margins, inarticulate. Spikelets 1-fld., minute, binate, a 

 sessile and a pedicelled, lanceolate, both awned and bisexual; callus 

 minute, ciliate. Glums 3 (III absent) I linear-oblong, subcoriaceous, 

 5-6-nerved, dorsally flattened, tip broadly hyaline truncate irregularly 

 2-toothed, margins incurved, keels ciliate; II oblong, keeled, obtuse or 

 truncate, 3-nerved, ciliate towards the tip ; IV much shorter, very narrow, 

 cleft to the middle, lobes subulate; awn in the cleft, capillary, geniculate, 

 palea 0. Lodicules cuneate. Stamens 3, anthers oblong. Styles short, 

 free. Grain subfusiform, terete, grooved one side. 



A remarkable genus, with the habit of Arthraxon (closely resembling A. micro - 

 phyilus), next which it may be provisionally placed, but not nearly related to it, 

 differing in the inarticulate flat rachis of the simple spike, bisexual awned pedicelled 

 gpikelets, and absence of gl. III.

NORTH WESTERN HIMALAYA ; growing amongst moss, Falconer. 



Stems 6-8 in., very slender, sparingly branched, leafy to the tips, filiform j 

 internodes concealed by the leaf-sheaths. Leaves -j-f in., flat, acute or acuminate ; 

 sheath deeply furrowed, glabrous ; ligule a few hairs. Spikes ^-1 in., very slender, 

 green, peduncle capillary as long as the leaf-sheath ; rachis exactly linear, flexuous, 

 quite glabrous, not disarticulating at the transverse glabrous nodes. Spikelets 

 -J^ in. long, rather longer and broader than the internodes ; gl. I with the 2 lateral 

 (carinal) nerves only reaching the tip ; II with a stout median nerve and 2 very 

 slender lateral ones anastomosing with it below the tip. 



42. THELEPOGON Roth. 



A coarse perennial grass. Leaves lanceolate, base cordate, amplexicaul. 

 Spikes few or many, corymbosely fascicled, peduncled, lower whorled, upper 

 distant ; rachis flexuous, fragile ; joints more or less deeply excavated. Spike- 

 lets solitary at the joints, with the rigid pedicel only of an upper, ovoid, 

 acute. Glumes 4, 1 thickly coriaceous, convex, beaked, transversely rugose 

 ridged or tubercled ; II sunk in the cavity of the joint, rigid, sparingly 

 tnbercled, acuminate; III shorter, hyaline, paleate, usually male; IV 

 bisexual, hyaline, deeply bifid, with a long twisted awn in the sinus ; palea 

 narrow. Lodicules broad. Anthers 3, very long. Styles free, stigmas 

 short. Grain narrowly oblong, free.

Stems 6 in. 3 ft., tufted and branching from the base, or woody as thick as a 

 crow-quill 1 elow and geniculately branching upward ; roots stout, rigid. Leaves 

 3-10 by i-f in., lineur, acuminate, ratlier thin, and sheaths glabrous scabrid or 

 hispid with tubercle-based hairs, margins denticulate; lignle very short. Spikes 

 1-3-1 in., peduncle slender, stiff; rachis compressed, much mi rrower than the spikelets, 

 of upper spikelets tubercled ; joints as long as the spikelets, subclavate, scaberu- 

 lous, top orbicular cupped. Spikelets | in., yellow or brown ; callus annular, 

 bearded; gl. I very thick, hard, beak echiuate; II with usually one transverse row 

 of tubercles; III broad, 2 -nerved, glabrous; palea narrow, acute, nerveless; IV 

 ovate -lanceolate, 3-nerved, glabrous; lobes lanceolate, 1-nerved; awn = 3-4 gl. in
