This striking Odontoglossum appeared quite unexpectedly 
as a single plant in Messrs. James Veitch & Sons’ Nur- 
sery at Chelsea, in 1882, and was described by Reichen- 
bach as a doubtful natural hybrid, the author remarking 
that it was distinguishable from O, deltoglossum, Reichb. f., 
by its far longer and narrower lip and bright yellow 
ground colour. No. clue was given as to the habitat or as 
to the species along with which it was imported, and the 
point is still veiled in obscurity. In 1887 Messrs. Veitch 
reduced it to a variety of O. odoratum, Lindl., though re- 
marking that it was of supposed hybrid origin, while soon 
afterwards Reichenbach made it a variety of his O. lanceans, 
a name which he proposed to include the large and poly- 
morphic series of natural hybrids believed to have arisen 
from the intererossing of O. erispum and O. gloriosum. 
Here it remained for a considerable period, quite anoma- 
lous in its deep yellow ground colour. In 1902 a second 
plant appeared, also unexpectedly, in the establishment of 
JuLy ‘ist, 1907.
