Stems 6-12 in., usually diffusely spreading, rarely erect. Leaves linear-lanceolate, 

 acute, glabrous; mouth of sheath hairy. Spikes 26, 12 in. long, suberect 

 or divaricate, green or reddish. Spikelets variable in hairiness ; the hairs often 

 with slightly clavate tips ; gl. II with rarely a minute one at the base ; III quite 

 smooth. Very similar to var. cruciatum of P. sanguinale, but has smaller brotider 

 not acuminate spikelets, and gl. IV is never acuminate. Even more like P. ternatum, 

 which is best distinguished by the brisUe-like hairs on the pedicel, and short clavate 

 ones on the outer gls. 



10. P. ternatum, Hoolc.f. ; stems erect or decumbent below, spikes 

 2-3 subdigitate erect or spreading, rachis narrowly winged ciliolate, spike-

Habit of P. ambiguum. Leaves 2-5 in., linear-lanceolate or linear ; sheath 

 glabrous or with a few hairfc, mouth ciliate ; ligule short, membranous, truncate. 

 Spikes 2-3 in., silvery-white. Spikelets pale, pedicels short, hispid with stift hairs, 

 the upper hairs half as long as the spikclet ; gl. land II with the hairs forming a 

 dense fringe along the margins.' The Belgaum. and Khasian specimens are tall and 

 long leaved ; the Bababudan ones very short. Said by Schimper to be a pest in 

 cultivated land in Abyssinia. It so closely resembles P. amMguum, that without 

 microscopical examination of the hairs of the spikelets it is very difficult to dis- 

 tinguish it from that species. A Ceylon plant; from Thwaites (C.P. 2573), with 

 larger spikelets than P. longiflorum (to which I doubtfully refer it), cannot 

 be distinguished from P. ternatum except by the structure of the hairs of the 

 spikelet.
