}t is now more than twenty years since the late Mr. Monteiro trans- 

 mitted excellent specimens of this rare Podostemad to Kew, some of 

 ^vhich I forwarded to the late Dr. Weddell, who had shortly before 

 been engaged on the Order for the *Prodromus.' His description of 

 He plant was in time to appear in the same volume as an addendum. 



ivr^^ ^^t since, so far as I am aware, been gathered by any collector. 



Mr. Monteiro describes it as occurring very sparingly on rocks in 

 the middle of the torrent; tlie stems when fre^h, thick, translucent, 

 and watery. I follow Dr. Warming (in Engler and Prantl, ' Pflanzen- 

 lamdien,' Podostemace^e), in referring Angolcea to his tribe Marathrese.
