208 THE ORCHID REVIEW. ~ [Juty, 1922. 
A rarity is to be seen in O. Lucasianum, a natural hybrid between crista- 
tellum and Hallii. 
The production of a blue Odontoglossum has on more than one occasion 
attracted the attention of hybridists, and although the problem cannot yet 
be said to:have been solved, there is here to be seen in O. Ardentisper and 
in O, Ardentellus two of the nearest approaches to this pleasing colour. O. 
Othello is an elegant hybrid bétween Adriane (crispum X Hunnewellianum) 
and Harryanum, and the illustration herewith shows the happy combina- 
ODONTOGLOSSUM OTHELLO (HARRYANUM x ADRIAN 22). 
tion made by these three species; it received an Award of Merit, R.H.S., 
April 16th, 1907, when exhibited by Mr. C. J. Lucas. In O. Fascisolon, 
which was first raised in this collection, there exists a batch of hybrids which 
show considerable variation: some are unusually pretty, while others are 
very plain. Other promising Odontoglossums are Purple Queen, Panther, 
Jasper, the Warnham Court variety of Britannia, Lambardeanum and Fabia, 
the latter having been awarded a Certificate of Appreciation by the Royal 
Horticultural Society. Seed-raising is being continued, and the little 
seedlings, after being removed from the parent pots, are taken care of for 
the first few months of their existence in small glass cases placed upon 
the staging in this house. Growing on a raft suspended from the roof are some 
fine pieces of the straggling Odontoglossum brevifolium, which flower freely.
