40 CLXXIII. GRAMINE^E. (J. D. Hooker.) [Panicum. 



eliort, rounded. Panicle 6-12 in., rarely 1 in. diam., often interrupted, sometimes 

 quite cylindric. Spikelets erect, very shortly pedicelled, pale green; gl. I broadly 

 ovate, acuminate ; III tapering into a long rigid erect beak, palea or imperfect. 

 Generally cited as P. wyurus, of Lamk, but as Nees has pointed out (Agrost. Bras. I.e.) 

 Lamk's plant is Richards' P. myosurus (= P. indicum). In Muuro's herbarium 

 P. tryurus is, perhaps rightly, referred to P. amplexicaule, Rudge (PI. Gui. i. 21), 

 which is a much broader leaved plant. 



20. P, assamicum, Book. /. ; slender, erect, leaves narrow base 

 rounded, panicle spiciform cylindric very narrow interrupted, spikelets f in. 

 densely crowded on the appreesed branches, gl. 1= III 3-nerved, II and 

 III lanceolate 5-nerved, III rather longer than II epaleate, IV ovate- 

 lanceolate thin smooth. 



ASSAM, Masters, Griffith ; DACCA, Clarice. 



Stem 12-18 in. or more, ascending, as thick as a sparrow's quill, lower nodes 

 rooting. Leaves 2-4 in., narrowed from the base to the acute tip, margins quite 

 smooth, involute (when dry) ; sheath glabrous or mouth slightly hairy ; ligule a 

 narrow membrane. Panicle 3 in., hardly ^ in. diam., pale green, quite glabrous. 

 Spikelets very shortly pedicelled ; glumes thin. I advance this species with hesita- 

 tion. It is nearest to P. myurus, differing in size, narrow leaves, very narrow 

 panicle, smaller spikelets, and shorter glume III.

Perennial. Stem 3-6 ft., sometimes as 'stout as a goose-quill, soft. Leaves 8-14 

 by f-1 i in., glabrous or sparsely hairy beneath, as is the, sheath; mouth villously 

 bearded ; ligule very narrow. Panicle 8-18 in., green, rachis scaberulous, branches 

 2-5 in., branchlets and fascicles of spikelets subsecund. Spikelets green, glabrous, nerves 

 strong; gl. I broadly ovate; II and III ovate-oblong; palea of III small; IV as 

 long as III, white, thinly coriaceous. The Ceylon specimens have longer ( T y-i i"-) 

 narrower and more acuminate spikelets than the normal.
