Under Phippsia (p. 210), I indicated the affinity of that genus with Colpodium. 

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

 me the possibility of these, together with Duponiia, forming one genu?. I accord- 

 ingly drew Di\ Stapfs attention to the group, and requested him to give wem 

 opinion. This lie has done, confirming niy hypothesis and drawing up a systematic 

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

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

 Colpnditm group in the empty gls. being minute or obsolete, and may licuce 

 considered as forming a section by itself, whilst P. 7/ima?a/ca, with larger enipi} 

 gls., enters that of Colpodium, The position of Qatahrosa is after Poa, replaciufe

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

 ascending branched stolons.
