A most remarkable plant, belonging to the winged section 
of Torch thistles, according to Pfeiffer, which Link regards as 
a peculiar genus and calls Phyllocactus.. It is the finest thing 
yet known of its class with white flowers, and will doubtless 
prove invaluable as a breeder ; for its habit is beautiful, to say 
nothing of its magnificent flowers, which rival the night- 
flowering Cactus, but open in the day time. When pro- 
duced last month at the exhibition in the Horticultural So- 
ciety's Garden, it received the highest medal offered for new 
plants. Let us only imagine a cross between it and C. ~ 
speciosissimus or Ackermanni ! 
For the following information concerning it we are in- 
debted to Mr. Booth. 
This fine species, with several others, was forwarded from 
Honduras in 1839 by George Ure Skinner, Esq. and pre- 
sented to Sir Charles Lemon, Bart. M, P. with whom it 
flowered at Carclew in May 1843. Although similar in some 
respects to .Ep. latifrons of Botanical Magazine, fol. 26927 it 
proves to be perfectly distinct and far more desirable, on ac- 
. count of its flowers opening in the day time and E 
expanded for nearly a week, whilst those of the one refe 
to open in the evening, are in perfection at midnight, and 
finally close a little before sunrise. It is also proper to state 
that in addition to their other recommendations the flowers 
of this species are deliciously fragrant, which will no doubt 
render it a most valuable acquisition to the admirers of this 
singular tribe of succulents. 
The plant grows about two feet high with large spreading 
branches, some of which in their young state are round and 
angular, with bristly hairs at the joints, resembling the young 
shoots of Cereus speciosissimus. Their most usual form,
