ince the Odontoglossum crispbum has been discovered on the mountains 
of New Grenada, more than half a century ago, it has given birth to 
numberless varieties, and the list of the most typical, of those which. 
ioe received a particular name, would at the present time be long indeed. 
Several of these varieties, such as O. Alexandrae, O. Bluntiit, O. Chestertonii, etc., 
were even at first considered as distinct species. O. Andersonianum, O. Fen- 
ningsianum, O. linbatum, O. Ruckerianum, have been described by some authors, 
and specially by Messrs. Veircu, as varieties, of O. crispbum; but they are more 
commonly considered as natural hybrids between this species and one or the 
other of its neighbours. 
One might suppose that, the region where this species, so commonly cul- 
tivated grows and of which hundred of thousands of plants have been introduced, 
had been throughly explored and that nothing further could be discovered there, 
especially when we consider the length of time this region has been open to 
explorers. However, such is not the case, and great was the excitement amongst 
the Orchidists when, quite recently, the Messrs Linpen exhibited a series of new 
varieties one after the other, several of them surpassing in beauty those hitherto 
seen in Europe. 
Some of these new varieties were exhibited at the Meeting of the Brussels 
ORcHIDEENNE, On the 19" of last April, and were greatly admired. O. crispum 
Calos coming foremost on the list. The flowers of this variety are 4 inches in 
diameter. The sepals and petals are rather broad, the edges slightly wavy, 
with a pure white ground; each bearing one blotch in the centre, but very 
large, rounded irregularly, of a deep blood-red colour, which on the sepals 
gradually becomes paler towards the apex. The lip is pure white, with the 
exception of the central part, which is orange-yellow and is surrounded by 
several red-purple blotches. The column is variegated with yellow and red.
