Fhrajmites."] CLXXIII. GRA.MINK.E. (J. D. Hooker.) 305 



P. communis, and F. Mueller observes (in a letter to Bentham) that they are so in 

 the Tasimmian P. communis; whereas in the tropical Australian plant which Bentham 

 includes under it they are evergreen. 



Var. cincfa ; spikelets scaberulous, pedicels villous with silky hairs. P. cincta, 

 C/arke mss.- Xear Calcutta; Salt Lakes, Kurz ; Mutlah, Clarke. The specimens 

 sire in a very young state of flower. The glumes are identical with those of P. Karka,, 

 in which latter the pedicels of specimens from all parts of India are quite glabrous. 



97*. NEYRAUDIA, Hook,f. (Genus not in clavis}. 



A tall perennial leafy grass. Leaves long, flat. Spikelets small, 4-8- 

 fld., in an effuse decompound nodding panicle, laterally compressed, lowest 

 flg. gl. sometimes glabrous epaleate and neuter; rachilla shortly bearded 

 below the flg. gls., jointed at the base (above the neuter gl. if present) and 

 between the flg. gls. Glumes all membranous ; I and II unequal, empty, 

 lanceolate, 1-nerved; flg. gls. elongate-subulate, more or less recurved, 

 ending in a very slender tip with 2 setaceous points and a scabrid inter- 

 posed awn, 3-nerved, lateral nerves submarginal, penicillate with long 

 hairs ; palea oblong, keels scaberulous. Lodicules 2, obovate or cuneate. 

 Stamens 3, anthers long linear. Ovary shortly stipitate, oblong ; styles

The PANJAB and TROPICAL HIMALAYA, from Chamba to Sikkim, ascending to 

 5000 ft. SILHET and the KHASIA HILLS, ASSAM, PENANG and BURMA. DISTEIB 

 Tropical E. Asia and Malaya. Trop. Africa, Madagascar. 



Stem 6-8 ft. (or more?) up to ^ in. diam., leafy to the panicle or near it, 

 polished, solid, glaucous at the nodes. Leaves 1-2 ft., from filiform and convolute 

 to 1 in. broad and flat, smooth, rather soft, margins smooth or nearly so, midrib 

 and few nerves slender, base subamplexicaul; sheaths polished; ligule a villous 

 ridge. Panicle 1-3 ft., rachis and filiform fascicled and whorled branches smooth 

 or subscaberulous, ultimate branchlets capillary. 8/jilcelets -J in. (including the 

 awns), shortly pedicelled, pale brown, 4-8 fld. ; gl. I and II shining, I ^ shorter 

 than II; neuter gl. if present f J- in., about twice as long as I, strict, spreading, 

 oblong-lanceolate, suberect, 3-nerved, sides convolute, quite glabrous; flg. gls. 

 longer than the empty, more or less recurved, very slender, narrowed into the more 

 or less recurved not twisted scaberulous awn with two bristles at its base j palea 

 hyaline, 2-toothed, keels minutely ciliolate ; callus, the upper portion of each inter- 

 node of the rachilla, jointed with the latter, densely shortly beai-ded. A. much 

 more elegant grass than any Indian species of Arundo or Phragmites, but like these 

 extremely variable in habit and size, depending on place of growth. I can find no 

 difference whatsoever between the specimens with and those without the empty gl. 

 Ill ; specimens with filiform leaves occur in both. Their habitats are as follows : 



1. madagascariensis proper ; neuter gl. 0. Western Himalaya ; from Kashmir 

 to Kumaon, Rangoon, Prome. Africa, Madagascar. 



2. Zollingeri; neuter gl. present. Arundo Reynaudiana, Kunth I.e. Sikkim 

 Himalaya, Assam, Bengal, the Khasia Hills, Chittagong, Tenasserim, Penang. 

 Java.
