annexed engraving is made. This species was, I believe, 
one of Mr. Hrrcuin’s collection, who received it from the 
continent under the name of Epreaytium oxypetalum, 
(Cereus oxypetalus, D C.) which Dr. Preirrer, it appears, 
justly considers the same as the C. latifrons of Zuccarint, 
a much more appropriate name it must be confessed. It is 
certainly very nearly allied to our C. phyllanthus (Bot. 
Mag. t. 2692, the C. phyllanthus, var. flore majore of Dg 
Canp., C. Hookeri, Haw., and of Preirrer and Orto, Cac- 
tées, tab. 5.) These latter authors say, that it differs from 
C. Hookeri “ par la crénelure de ces rameaux et par la 
forme de sa fleur :” but these distinctions are not very evi- 
dent, even in their own figures. It flowers in August. 
Descr. A tall-growing plant, incapable of supporting 
itself, jointed and proliferously branched ; the branches and 
jomts elongated, very broad and compressed, with an ele- 
vated nerve or costa in the middle, and which sends out a 
branch where a flower arises, the margin crenulated, some-_ 
times tinged with purple. From a crenature of the mar- 
gin the flower arises, which is peculiarly large, solitary, and 
handsome. Tube very long and slender, tinged with pur 
ple, and beset with purple or reddish scales, which gradually 
pass into the calycine segments, and these almost impercept- 
ibly into petals : the latter are pure white, lanceolate, acu- 
minated. Stamens long, numerous, yellowish-white. Style 
red, longer than the stamens. Stigma of many yellow rays:
