of Cereus. To the first section he gives the name of Main- 

 milaria, and to the seventh that of Epiphyllum, Phyllanthus 

 being already occupied. His other genera all retain the 

 names given to the different sections. 



Cactus speciosissimus, belongs to the third section. This 

 plant having been already published under this name in 

 the Memoires of the museum of Natural . History and in 

 the Botanical Register, -we adopt it to prevent confusion, 

 though that of speciosus has the right of priority. The 

 speciosus of M. Bonpland was first described and accurately 

 characterized by M. De Candolle under the name ofphyl- 

 lanthoides, (vide supra n. 2092.) 



Native of South America. Requires to be kept in the 

 dry stove and treated as other tender succulents. 



Introduced from Paris by the Count De Vandes, in whose 

 collection at Bayeswater, the plant from which our drawing 

 was taken flowered in great perfection, in July last, as it 

 had done the preceding year. The gardener remarked 

 that the red streak to be seen in our drawing below the 

 flower-bud, constantly denoted the tubercles from which 

 the flowers would proceed, and this some time before the 

 appearance of the bud.
