Perennial soft grasses ; stem erect or creeping below ; innovations 

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

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

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

 more, uppermost usually imperfect ; I and II 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. Lodiruhs 2, minute, fleshy. Stamens 3. 

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

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



Under PMppsia (p. 240), I indicated the affinity of that genns with Colpodium, 

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

 ine the possibility of these, togetlier with Dupontia, forming one genus. I accord- 

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

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

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

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

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

 considered as forming a section by itself, whilst JP. Mmalaica, with larger empty 

 gls., enters that of Colpodium. The position of Catahrosa is after Foa, replacing 

 119. Colpodium in the Key to the Genera. 



§ 1. Catabeosa proper. Empty gls. almost nerveless; flg. gls. strongly 

 3-nerved, rarely with 2 intermediate fainter nerves.- — ^Aquatic or siibaquatic 

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

 ascending branched stolons.
