HYBRIDISATION VIEWED FROM SYSTEMATIC BOTANY. 193 
Of the five or six distinct wild Lelio-cattleyas known, only one has 
been raised artificially—namely, L.-c. x Schilleriana, obtained by Messrs. 
Charlesworth & Co., from Lelia purpurata 2 and Cattleya intermedia 3 
(* Orch. Rey.,’’ 1898, p. 167). Asa wild plant it has been known ever 
since 1855, in which year it was described as a species, under the name 
of Lelia Schilleriana. There are, however, seedlings in existence which 
ought to prove the parentage of two if not three others. 
One other Odontoglossum claims a place in our list—namely, O. x 
elegans, described by Reichenbach, in 1879, as a natural hybrid between 
O. cristatum and cirrhosum (‘* Gard. Chron.,’’ 1879, xi. p. 462). Messrs. 
Linden, however, have raised an identical hybrid by crossing O. cirrhosum 
with the pollen of O. Hallii. It flowered early in 1897, and was described 
Fie. 97.—OponrocLossum x ELEGANS. (Mr. Pollett’s Catalogue.) 
and figured under the name of O. cirrho-Halli (“ Lindenia,” xi. p. 85, 
t. 569). 
Phalenopsis x Veitchiana-appeared as a solitary specimen among 
Philippine importations of Messrs. James Veitch & Sons, and flowered in 
1872, when it was described as a natural hybrid between P. Schilleriana 
and P. rosea (Rehb. f. in “ Gard. Chron.,”’ 1872, p. 935), a view since con- 
firmed by Messrs. Heath & Sons, who have obtained it asa seedling from 
the former crossed with pollen of the latter (Hansen, “ Orch. Hyb.,”’ 
p. 331). 
Lastly, and scareely less interesting than any of the preceding cases, 
we have the remarkable fact that Dendrobium x Ainsworthii has
