To the Editors of the Philosophical Magazine and Annals. 



Gentlemen, 



HAVING just examined a new and specious plant of the 

 subgenus Epiphyllum of the Cactecan order, at Mr. Tate's 

 choice Nursery, in Sloane-street (where so many new tropical 

 plants are found), I send you hereunder a full description of it. 

 And in order to make the communication a little more accepta- 

 ble to your botanical readers, I have added to it a monographi- 

 cal sketch of all the other sjjecies of Epiphjllum, with new sec- 

 tions and characters to elucidate the whole, as far as known to 

 me, which arc seven in number. The new species is named 



t Charactcri from Stcplicns's lUtttt. liril. Ent, Uaust.U. p. 139.
