by \-\ in., narrowly linear, tips capillary, rather coriaceous, 

 keeled, glaucous, glabrous or ciliate towards the narrow base, 

 smooth on both surfaces, margins slightly scaberulous, sheaths 

 glabrous, mouth not auricled, ligule a very short ciliate 

 membrane ; panicle 4-6 in., erect, contracted, rhachis slender, 

 smooth, branches \-\\ in. long, lower whorled, upper alt., 

 branchlets or spikes up to 1 in., erect, slender, rhachis capillary, 

 fragile, smooth ; sessile spikelets \ in long, longer than the 

 internodes, linear-oblong, pale, callus very short, bearded ; 

 glume I thin, obtuse, 4-9-veined, dorsally smooth, margins 

 narrowly incurved, rigidly ciliate above the middle, II as long 

 as I, oblong-lanceolate, acute, veins o or 3 faint, smooth, 

 eciliate, III much shorter, oblong, obtuse, veinless, eciliate, 

 IV the slender colourless base of the capillary geniculate 

 awn, which is about twice as long as the spikelet, column 

 minutely roughened ; pedicelled spikelet rather smaller and 

 narrower than the sessile, pedicel more than half as long as 

 the latter, slender, glabrous or ciliate. 



Hot drier parts of the Island (Thwaites). 



Throughout Trop. Asia and Africa, Australia and the Pacific, also in 

 the Caucasus. 



There is only one sheet of this in the Peradeniya Herbarium, with 

 the habitat between Haputale and Badulla. A. intermedia is a variable 

 plant in India. Hackel has four varieties of it, and refers the Ceylon 

 plant to var. Hcenkei, distinguished by its compound panicle 5-6 in. long, 

 with the branches bearing 4-8 spikes, the sessile spikelets § in. long, 

 glume I rarely pitted and its margins rigidly ciliolate. The variety 

 punctatus (A. punctatus, Trin.) which is common in India has not hitherto 

 been found in Ceylon ; if found, care must be taken not to confound it 

 with A. pertusus.
