232 REPORT OF THE CONFERENCE ON GENETICS. 
natural hybrid between C. Harrisoniana and C. Forbesii, having the 
shape and colour of the former, with a lip showing the characteristic 
markings and verrucose disc of the latter. 
In 1895, Cattleya x O’ Brieniana was added to the list of probable 
natural hybrids, the supposed parents being C. dolosa and C. Loddigesii 
(Rolfe in “Orch. Rev.’’ 1895, p. 11). It was originally considered a 
distinct species (“ Gard. Chron.” 1889, ii. p. 700) and afterwards a 
peculiar form of C. Loddigesii (Rolfe in “ Reichenbachia,” ser. 2, i. p. 85, 
t. 40). In 1895 a plant flowered with M. A. A. Peeters, of Brussels, 
which had been imported with C. dolosa from the province of Minas 
Fie. 54.—Lauio-Carrieya x Prrrmana. (Gardeners Chronicle.) 
Geraes, Brazil, and proved identical with Messrs. Sander’s original plant. 
The characters are clearly intermediate between the two parents. 
Lelia x venusta (Rolfe in “Orch. Rey.” 1895, p. 47) originally 
appeared in the establishment of Messrs. James Backhouse & Sons, of 
York, in 1884, having flowered, it is said, “last autumn,’ and was 
described under the name of L. autwmnalis var. venusta (Goldring in 
“ Garden,’ 1884, i. p. 366, t. 488). Afterwards a plant appeared with 
Messrs. Sander, St. Albans, which Reichenbach called L. autwmnalis var. . 
xanthotropis (Rehb. f. in “ Reichenbachia,” ser, 1, i. p. 21, t. 10), and 
suggested that it might be a hybrid between LZ. autwmnalis and L. fur- 
furacea. After consideration of the known facts I came to the conclusion
