Stem 1-2 ft., erect, tufted, nodes glabrous. Leaves 6-18 in., erect, flexuous, 

 J J_ in, broad (except in Wallich's n. 8813), glabrous. Peduncle filiform. Spikes 

 |-2 in., fascicled, very slender, erect. Spikelets amongst the smallest of the genus ; 

 gl. IV very variable in length and in depth of lobing, sometimes subentire, awn some- 

 times 1 in. long. Hackel has two subspecies, one with the nodes of the spike longer 

 and not disarticulating, which includes the Burmese plant of Wallich, n. 8814, and 

 the Sikkim plant ; the other has fragile spikes with much shorter nodes, to which 

 Wallich's Burmese, n. 8813- belongs ; this latter is a much taller stouter plant with 

 leaves in. broad and stems thicker than a crow-quill. What Hackel describes as 

 gl. Ill appears to me to be the palea of gl. IV, for it surrounds the ovary.

SUBTROPICAL HIMALAYA j from Simla to Sikkim, the MISHMI, and KHASIA 

 HILLS, alt. 3-5000 ft., Clarke. PEGU, alt. 4-6000 ft., Kurz. DISTRIB. China. 



Stem 1-2 ft., leafy upwards, nodes glabrous. Leaves narrow, glabrous or' hairy 

 beneath, or on both surfaces, or with the sheath hirsute, tips finely acuminate; 

 ligule oblong. Spikes 3-5, 2-6 in., erect or flexuous. Spikelets pale yellow-brown ; 

 callus hairs long white; gl. I with hispid keels above, tip contracted minutely 

 truncate, margins rather broadly inflexed; II acute, minutely apiculate, sub 3-nerved, 

 keel smooth, margins ciliate; III linear-oblong, long-ciliate above; IV with the 

 adnate awn forked towards the base, lobes rounded ciliolate ; palea lanceolate, ciliolate. 

 Nees, as Hackel observes, errs in describing the base of the stem as rufous-hajred. 

 The Khasia plant has softly villous foliage and has paler spikes, and closely resembles 

 P. speciosa, var. heterotricha. 



Var. Wightii ; stem tall stout silky below the panicle, leaves \ in. broad acute, 

 spikes 3-7 in., spikelets nearly ^ in., gl. I 2-4-ncrved, IV cuueately obovate broadly
