Ill many i-cspccts this approaches G. refracta ; hut the spiculae are more deeply 

 coloured, shorter, narrower, and with fewer flowers ; and the panicle, of which there is 

 ;iii ext-ellont specimen in Burchell's collection, is much more compound, with the diver- 

 tjent hraiichcs inclining upwards. The leaves arc occasionally nearly as long as in G. re- 

 fracta, hut they arc much more attenuated at the points, and generally very much 

 narrower.

The specimens which 1 have seen of this arc very imijeilect ; but 1 think it is readily 

 distinguishable from G. refracta by its much smaller leaves and the long fringe on one 

 side of the vagina. The single branch of the panicle which I have seen is also very much 

 more compound, and the spiculae more hirsute, than in either of the two preceding 

 species. 



All these last three species are certainly very closely allied, especially in the structure 

 of the spiculae, although they are remarkably different in general appearance. They have 

 all the same obovate form of ovary that is found in Bumbusa tulda and allied species ; 

 and the keels of the upper palea are very much less winged than in any of the ten other 

 sjiccies of Guadiia. Consequently there remains but little except their geographical dis- 

 tribution and their peculiar hairy petioles to separate them from the genus Bambutia, in
