processes are 0 leiily desta with ifurple, and fntetrially the lip 
is yellow ; ; its teeth are longer and more acute. C. Claverin- 
_ gi is described as having its flowers very evanescent, expanding 
slightly in the middle of the day, and diffusing a faint smell 
like myrrh. The blossoms of the present plant are perfectly 
scentless: they continued in great perfection for three or four 
days in the stove, without exhibiting any symptoms of decay, 
and the flower-stalk having been then cut off, it continued in 
great beauty for almost a. week longer. 
C. Claveringi is a native of Brazil. 
Mr LINDLEY enumerates five certain and one doubtful 
species of Catasetum. The subject of the present plate adds 
another to this truly noble genus. 
It was not difficult, in this individual, to distinguish the 
cause of the highly elastic property of the pollen-mass. It re- 
sides in the stalk of the masses, which is a thin, broad, mem- 
branaceous, and very tough plate. It is spread over a convex 
surface on the front of the column, whilst the masses them- 
selves are in a measure confined in a hollow above, and the 
large gland is held in by another hollow below the swelling. 
‘When the anther-case is removed, the plate quits the spot 
where it was before retained, and its margins rolling in sudden- 
ly and quickly, the whole is thrown off with a jerk to a great 
distance. ‘The cavity at the base of the gland is filled with 
a thick, white, glutinous substance of an unpleasant smell.

petals forced open. Fig. 2. Column, with the pollen-masses as they 
appear whilst the anther-case is carefully and artificially removed.

Garden, and differs only in colour from our C. floribundum. 'The lip is pure yellow in 
the inside, and all the petals are of a pale purplish colour, all of them minutely spotted 
with purple within, and obscurely so even without. The margin of the lip is indeed 
slightly ciliato-crenate (a mark I may have overlooked in the plant above describéd) ; 
and this will bring it near to the C. maculatum of Humpotpt and Kuntu. At Fig. A. 
a flower of this variety, as I consider it, 1s represented.
