THE ORCHID REVIEW. 267 
Rio de Janeiro or Minas Geraes, where both species are found, but a hybrid 
between them would scarcely have deep purple sepals and petals, and I am 
inclined to suspect that C. Harrisoniana was the second parent. We have 
evidence that it grows with C. intermedia and C. Forbesii, so that there 
does not appear to be any geographical difficulty. In a short Latin descrip- 
tion it is added that the petals are much broader than the sepals, and this 
again is not suggestive of the narrow-petaled C. intermedia. Hybrids of 
C. bicolor usually have small side-lobes, much shorter than the column, but 
there is no allusion to this point in the description, unless the remark that 
they are triangular bears this interpretation. There seems, however, no 
reason to doubt that C. bicolor was one parent. It would be interesting to 
know if the original plant is still in existence, or any drawing of it. I have 
not yet succeeded in matching anything with the description, which 
suggests that the hybrid must be very rare in a wild state. 
There is a second natural hybrid which should be compared with the 
preceding were the necessary materials available, namely Cattleya X 
sororia, which appeared about ten years later, and was described by 
Reichenbach as follows (Gard. Chron., 1887, i., p. 40) :— 
“ CATTLEYA X SORORIA, lybr.—This was kindly sent me by Mr. B. S. 
Williams, who informs me it was introduced from Brazil, and that it has 
the growth of Cattleya bicolor. I hope to be forgiven for my keenness in 
declaring it a hybrid, which, indeed, is a guess. The flower looks like a 
good extra-strong flower of Cattleya Harrisoniz, and has greenish-yellow 
tips to the sepals. There are small, very much darker spots on the petals, 
more numerous inside than outside. The lip suggests undoubtedly the 
impression of that of Cattleya Walkeriana. The side laciniz are cut in a 
similar manner, and do not fully cover the rather broad column. They 
project into a short stalk, narrow in front, and the anterior lacinia is 
triangular, retuse, emarginate (or trapezoid), with small lobules at the sides. 
It is white, with the lightest purple at the margin, and a few dark purple 
lines at the base; there are also some purple spots on the stalk. There is 
an accumulation of asperities on the disc of the anterior lacinia, which 
reminds one of Cattleya guttata. Column strong, white, with some purple 
lines in front and some yellow at the base. I cannot help thinking of 
Cattleya Walkeriana, from the appearance of the lip and then of Cattleva 
guttata. Mr. B. S. Williams has sent me several times fine varieties of the 
first species, so that he has command of a hunting ground whence to obtain 
it. It is none of those numerous novelties raised at the Royal Exotic 
Nursery of Messrs. Veitch & Sons, by Messrs. Dominy and Seden. Only 
Cattleya X Brabantize is comparable to it in its lip.” 
Soon afterwards it was figured in the Orchid Album (vol. vii., t. 307) the 
authors remarking :—
