234 REPORT OF THE CONFERENCE ON GENETICS, 
and I. harpophylla (Orch. Rey.’’ 1900, p. 122), but the evidence is 
not yet conclusive. It would be interesting to cross the two species 
together. 
Leliwo-Cattleya x Binoti (Cogn. in “Gard. Chron.’ 1900, ii. p. 370) 
flowered in the establishment of M. A. A. Peeters, St. Gilles, Brussels. It 
was found among a consignment of Cattleya bicolor sent from Brazil by 
M. Binot, and was described as a hybrid between this and some Lelia, 
probably some form of ZL. pumila. Shortly afterwards an artificially 
raised hybrid, possessing similar characters, flowered in the collection of 
the Right Hon. J. Chamberlain, M.P. It had been obtained from Messrs. 
W. L. Lewis & Co., though without this record of parentage (‘Orch 
Rey.” 1901, p. 304). 
Lelw-Cattleya x delicata (Rolfe in “ Orch. Rey.’’ 1901, p. 61) flowered 
two years previously at Kew, having being sent from the collection of the 
Right Hon. J. Chamberlain, M.P., as Lelio-Cattleya x amanda, under 
which name it had been purchased as an imported plant. But it proved 
different, and was recorded as a natural hybrid between Lelia crispa and 
Cattleya Forbesii, whose characters it combines. It has since flowered 
annually in the collection. 
Cattleya x Dayana (Rolfe in “ Orch. Rey.’’ 1902, p. 292) dates back 
to 1886, when it flowered in the collection of J. Day, Esq., of Tottenham. 
It was painted on August 7 (“Orch. Draw.’’ li. t. 35), when Mr. Day 
remarked: “From a plant of my own, bought of Messrs. J. Veitch & 
Sons, in flower. I consider it a spotted form of C. Forbesti, but have 
sent a sketch of it to Prof. H. G. Reichenbach.’ In the index of the 
volume occurs the note ‘‘ Forbesii guttata ?”’ indicating a suspicion that’ 
it was a hybrid between them; and it is so unmistakably intermediate 
between the two as to leave no doubt of its descent. 
Cattleya x Pilti@ appeared in 1895, being exhibited by H. T. Pitt, 
Kisq., Rosslyn, Stamford Hill, at a meeting of the Royal Horticultural 
Society on May 23, as a natural hybrid between C. Harrisoniana and 
C. Schilleriana, and received a First-class Certificate (Gard. Chron.” 
1905, i. p. 833). It appears to be a form of the earlier C. Lucieniana, 
Rechb. f. 
Cattleya x Schrederiana is a very recent addition to the list (Rolfe in 
“Orch. Rey.” 1905, p. 314). It was described as a species by Reichen- 
bach as long ago as 1883 (Gard. Chron.” 1883, ii. p. 102), when intro- 
duced by Messrs. Sander, being afterwards reduced to an anomalous 
variety of C. Walkeriana (Veitch ‘‘Man. Orch.” ii. p. 50). I have long 
suspected it to be a natural hybrid, on account cf the small side lobes to 
the lip, and at length made out its parents to be C. dolosa and C. bicolor. 
It is said to be a native of the province of Minas Geraes, and I believe 
came home with C. dolosa. (Fig. 55.) 
At the same time I indicated C. eximia (Rodr. ‘Gen. et Sp. Orch. 
Noy.” i. p. 70), described as long previously as 1877, from a single 
individual, as possibly a natural hybrid between C. bicolor and C. 
Walkervana. It was found on the borders of the Rio Parahybo, in the. 
province of Rio de Janeiro. 
Two or three suggested natural hybrids have been excluded from the 
preceding list, namely, Cattleya velutina, C. Dormaniana, and Lelia
