NATURAL HYBRID CATTLEYAS. 
A VERY interesting correspondence with M. Forget respecting Cattleya x 
bahiensis is related on another page, and I have now to thank him, and 
Messrs. Sander & Sons, St. Albans, for some very important information 
respecting the distribution of the Brazilian Cattleyas, in collecting which 
he has had so much experience. In my paper on “Natural Hybrid 
Cattleyas” (R.H.S. Conf. Genetics, pp. 222-241) I remarked :—“ Our 
knowledge of the geographical distribution of some of the species is still 
very imperfect,” and also “‘ Horticultural collectors might make some useful 
contributions to this interesting question.”” Finding that M. Forget was 
in England, I sent him a copy of my paper, requesting the favour of a 
candid criticism of its contents, so far as his experience permitted, and any 
information as to the species which he knew to grow intermixed. His 
reply is extremely interesting, and contains numerous important facts, and 
it will be best to present it aS nearly as possible in its original form. It 
follows the sequence of my, paper, which it will be remembered was a 
chronological one. The pages are given in brackets for convenience of 
reference. 
L2&LIO-CATTLEYA ELEGANS (p. 224).—Lelia purpurata grows inter- 
mixed with Cattleya intermedia and C. Leopoldi in the Island of Santa 
Catherina. But it also grows on the coast of the mainland, from the port 
of Santos, where it grows with Cattleya guttata, C. intermedia (amethystina), 
and C. Forbesii right along the coast to the State of Rio Grande do Sul. 
L.-c. AMANDA (p. 224).—Lalia Boothiana is found at the Gavea, 
especially at Sapiatoba and Cabo Frio, near Rio de Janeiro, where it grows 
in touch with Cattleya Forbesii, C. guttata, and C. intermedia. Lelia 
crispa is a cool grower and cannot have any contact with the above plants. 
CATTLEYA X HARDYANA (p. 225) comes from the State of Antioquia, 
particularly from Dabeiba and Ituango, the district for C. Dowiana aurea. 
C. gigas Sanderiana is quite distant from that region, and is found in the 
State of Cundinamarca, just below the Odontoglossum crispum district. 
It is in touch with C. Trianz bogotensis, and two years ago I found a 
hybrid between the two, but I do-not know if it still lives. 
C. X RESPLENDENS (p. 226) cannot be from C. granulosa, whichis from 
the State of Pernambuco, but is possibly from C. granulosa Schofieldiana and 
€. Schilleriana, which are found together in the State of Espirito Santo. 
C. x Lucreniana (p. 226) also cannot be from C. granulosa, but is 
“perhaps from C. guttata and C. Harrisoniana violacea or C. Forbesii. These 
Species are all very warm growers, occurring in the low-lands between 
the sea and the mountains in the Province of Rio. C. Loddigesii of the 
interior of Sao Paulo and Minas Geraes is a cold grower.
