HOLE : SOME INDIAN GRASSES AND THEIR CECOLOGY. 103 



Panicle attaining a length of 3 ft. but in depauperate specimens only 6 inches long. 

 Branches of flowering panicle spreading, arcuate, of fruiting panicle, erect, or ascending, 

 and adpressed to rachis. 



0'25 to 0'45 in. long, including the awn, 3 — 9 flowered, with two empty basal glumes, spikeiets. 

 (In addition to the empty glumes the lowest flowering glume, III, is sometimes epaleate, 

 neuter and glabrous, but this has not been found in the local plant.) 



Glume I. — Empty, lanceolate, 1 nerved, mucronulate, scaberulous dorsally on 

 nerve. Membranous, brown in colour. 



Glume II. — Empty, usually a little longer than I, oblong-lanceolate, mucronulate, 

 1 nerved, scaberulous or smooth dorsally on nerve. Membranous, 

 brown in colour. 



Flowering glume {Glume III). — Longer than the empty glumes, broad subulate, 3 

 nerved, with two lateral keels. Apex slender with two setaceous 

 points and an interposed scaberulous awn. Awn about \ length 

 of glume and recurved in fruiting spikeiets, but not twisted. 

 Dorsally villous with long white hairs along the keels. The 

 remaining flowering glumes are similar. 



Pale. — | to | flowering glume, oblong, 2 nerved, with two lateral keels, hyaline, 

 minutely scaberulous dorsally along the keels, glabrous. 

 Apex truncate, minutely two dentate. 



Lodicules. — Minute, two, cuneate or obovate, glabrous. 



Anthers. — Three, 0'07 in. long, yellow. 



Stigmas. — Two>, 0-03 in. long, hardly exserted from spikelet. 



The rachilla, which is continued beyond the upper flowering glume, is jointed at the 

 base above the empty glumes and between the flowering glumes. The portion of the rachilla 

 above the joint and below the next flowering glume ( = the callus) is densely bearded with 

 short white hairs. 



The fruiting spikelet breaks up at the joints of the rachilla, from the apex downwards, 

 the basal empty glumes persisting longest, 



B. — Taxonomy. 



82. In F. B. I. two forms of the species are 

 given : — 



(1) madagascariensis proper; neuter glume O. Western Himalaya. Burma, Africa, 



Madagascar; 



(2) Tolling eri; neuter glume present, Eastern Himalaya, Assam, Bengal, Burma, 



Java;
