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

 acute, glabrous; mouth of sheath hairy. Spikes 2-6, 1-2 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. — 7ery similar to var. cruciatwrn of P. sangvjitiale, but has smaller broader 

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

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

 ones on the outer gls.

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

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

 Spikes 2-S in., silvery-white. Spikelets pale, pedicels short, hispid with stitt hairs, 

 the upper hairs half as long as the spikelet ; gl. 1 and II with the hairs forming a 

 dense fringe along the margins. — The Belgaum and Kbasian specimens are tall and 

 long leaved j the Bababudan ones very short. Said by Sohimper to be a pest in 

 cultivated land in Abyssinia. It so closely resembles P. ambiguum, 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. longiftorum (to which I doubtfully refer it), cannot 

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

 spikelet.
