PoGONOPHORA, gen. nov. Crotonearitm, 



Male specimens of the plant distributed under this name had been 

 long known to me from Schomburgk's collections, and I had frequently 

 examined them, but in the absence of the female I was quite at a loss 

 as to what family to refer them. When I again received the plant 

 among Spruce's, although I still only found males, it became necessary 

 to determine them in some way, and my friend Mr. Miers kindly ana- 

 lysed them for me with his usual accuracy, and drew up a generic dia- 

 gnosis, so far as the male plant could supply it, believing it to be closely 

 allied to JExtoxicum, Villaresia, and Bursinopetahm, among Jqui/olia- 

 cet^. Mr. Spruce has now however sent female specimens of a slight 

 variety of the same plant, which at once show it to be a true Euphor- 

 biacea, and have enabled me to find females of the original variety 

 among the unarranged FlupliorUacecB of the Hookerian herbarium. I 

 am thus enabled to complete the character, which will place it in the 

 Tribe of Croton€(s, although it does not bear any immediate relation to 

 any genus hitherto published. The rudiment of an ovary in the males 

 (a somewhat further development of the central column of SipJionia) 

 and something of the general habit, show an approach to BuxecBy but 

 the ovules are constantly solitary in each cell.
