310 CLXXITI. GBAMINEJB. (J. D. Hooker.) [Koelena 



glabrous shining, tip of gl. I 2-toothed, awn of flg. gl. very short dorsal 

 above the middle of the gl. 



WESTERN TIBET, and Kishtwar, alt. 10-13,000 ft., Falconer, Thomson, &c. 



Stem 12-18 in., tufted, tomentose below the panicle. Leaves 3-5 in., very 

 narrow, glabrous, flat or convolute ; ligule short, lacerate. Panicle 1^-3^ in., rachis 

 tomentose. Spikelefs ^ in., shining, gls. I and 11 subequal or I rather the shortest, 

 both 1-nervedj rachilla laxly villous ; awn of flg. gl^. a little exceeding the gl. 

 itself. 



103. CATABROSA, Beauv. (by 0. Stapf). 



Perennial soft grasses ; stem erect or creeping below ; innovations 

 extra-vaginal. Leaves flat. Spikelets very small, 2- (rarely 3-4)- fid., 

 loosely panicled, oblong or obcomc, awnless, subarticulate on their pedicels; 

 rachilla jointed at the base, produced beyond the flg. gl. Glumes 4 or 

 more, uppermost usually imperfect ; I and IL very unequal, hyaline, empty, 

 persistent, 0-3-nerved ; I obtuse or truncate ; II broadly obcuneate or 

 orbicular; III and IV longer than II, broadly cuneate or flabelliform, 

 3-5-nerved, truncate, crenate ; palea as long as the gl., very broad, keels 

 smooth, glabrous or hairy. Lodicules 2, minute, fleshy. Stamens 3. 

 Stigmas subsessile, feathery. Grain obovate or oblong, free, glabrous. 

 Species 10-12, natives of cold or temperate regions. 



Under Phippsia (p. 240), I indicated the affinity of that genus with Colpodium, 

 and a further examination of the Indian plants referred to the latter, suggested to 

 me the possibility of these, together with Dupontia, forming one genus. I accord- 

 ingly drew Dr. Stapf 's attention to the group, and requested him to give me his 

 opinion. This he has done, confirming my hypothesis and drawing up a systematic 

 account of the Indian species to be included under Catabrosa. As to Phippsia 

 algida, the solitary arctic type of that genus, it differs from the other plants of the 

 Colpodium group in the empty gls. being minute or obsolete, and may hence be 

 considered as forming a section by itself, whilst P. himalaica, with larger empty 

 gls., enters that of Colpodium. The position of Catabrosa is after Poa, replacing 

 119. Colpodium in the Key to the Genera. 



1. CATABROSA proper. Empty gls. almost nerveless; flg. gls. strongly 

 3-nerved, rarely with 2 intermediate fainter nerves. Aquatic or subaquatic 

 plants, rooting at the lower nodes, and with usually long creeping or 

 ascending branched stolons.
