ODONTOGLOSSUM x VUYLSTEKEI VAR. THEODORA. 
‘THE accompanying reproduction of this Vuylstekean hybrid will be of 
interest now that the difficulties of Odontoglossum raising have been fairly 
vanquished by many of us in England. The parentage has not been satis- 
factorily proved, but remains as yet uncertain. Originally described by Mr. 
Rolfe (O.R. 1902, p. 99), it was at first thought that it might be O. triumphans 
X tripudians, but later (p. 170) Mons. Vuylsteke stated that he ‘“‘ never 
fecundated with tripudians, because its flowers are too small.” He had 
evidently forgotten that he had crossed with it, to raise O. X bellatulum, 
of whose parentage I have no doubt, having seen hybrids of two other

crosses to prove it, one batch being my own raising. In endeavouring to 
clear up the parentage, Mons. Vuylsteke wrote me on Jan. 14, 1903, that 
he thought it might be O. xX Wilckeanum albens and a natural hybrid 
much like his “‘ x President Zaldhua.” This latter plant I hope to see 
‘when in bloom, and the former is known quite well (under its five 
different names). The only description I have of O. X President Zaldhua 
states that it has ‘almost solid brown sepals, petals with yellow margins 
-and tips.” The lip and column are not mentioned, but it sounds very like a 
fine sceptrum. I cannot think there is any sceptrum in O. X Vuylstekei, for 
if so, there would be some evidence of its crest in the hybrid. Again,
