CATTLEYA BLUNTII. 
A good plant of that extremely rare form of white 
Mendelii which originally received the above name 
is now in flower in the collection of Major Lendy, 
Sunbury House, Sunbury-on-Thames, In beauty of 
form and substance it is by far the most charming of 
all white Cattleyas. The plant is one of a lucky 
six purchased from Messrs. Jas. Veitch & Son out 
of a fresh importation of their own, and the greater 
part of the other plants contained in un EA 
are fine and valuable forms. "Two now open а 
pure white in sepal and petal, but vidi lips of He 
richest erimson; another is pure white with a pen- 
cilling of crimson in the throat and violet blotches 
on the front of the labellum; and still another has 
sepals and petals of the colour of those of a good C 
Mossix, but with the crimson and frilled lip of С. 
_Mendelii. The Cattleyas and- Lelia purpur ata are 
cool-house plants, and the ig Se orar and Phalx-

for other trees be but spent upon it. It grows well 
under the drip and in the shade of other trees,
