ODONTOGLOSSUM x HUDSONI. 
Tue fact that Odontoglossum crispum grows in company with four other 
species in the Bogota district affords an opp y for the of 
ten distinct natural hybrids, and seven of these have already been 
definitely recognised, five being comparatively common. An eighth can 
now be added to = list. A plant has just flowered in the collection of 
Leopold de Rothschild, G bury House, Acton, which Mr. Hudson 
states was purchased with imported O. crispum, but on flowering it proved 
totally different. The flowers are comparable with both O. gloriosum 
and O. Hunnewellianum, in fact the characters of the two are com- 
bined in it, giving a clear indication of its origin. The plant most 
resembles O. gloriosum, and is quite distinct from O. crispum, the growth 
being more erect in character. The inflorescence has eight blooms, which 
have retained much of the general shape and the acuminate sepals and 
petals of O. gloriosum, except in being broader. The ground colour is 
light yellow, and the blotches are very numerous and dark brown, in fact 
they may be described as intermediate between the two species in colour 
and arrangement. The lip is distinctly pandurate, broadened above the 
constriction and then acuminate, markedly crisped, light yellow, with a 
whitish disc, and some red-brown blotches in front of the crest, which 
latter is two-lobed, but the lobes broken up into about four teeth. The 
column wings are broadly oblong, with a short oblique cirrhus in front and 
a few teeth behind. It might be roughly described as most like O. 
gloriosum in shape and [oy <aheamhaarpeanen’ in colour and markings. Its 
is very i g. The ions between O. Hunnewell- 
ianum and both O. | purp and O. Lindley should be looked 
for, as it would be extremely interesting to complete the series, if these two 
also occur.

CATTLEYA FORGETIANA. 
AT the R.H.S. meeting, held on April 3rd last, a very interesting Cattleya 
was exhibited by the Marquis de Wavrin, ees te Ronsele, Ghent, under 
the name of C. Forgetiana. The two-fl i has now been 
forwarded through Messrs. Sander and Sons. 8 Sander writes :—‘‘ Some 
four years ago I sent Forget up the St. Francisco River. He found little: 
among other things, two or three plants of this Cattleya. Only this one 
has flowered. I cannot make it out at all. It is not Brymeriana, and 
nothing near any other Brazilian natural hybrid. It may be a species. I 
think it is, in fact; of course, not good enough to collect nowadays, but I 
think that the near quarters of the St. Francisco River hide many
