ODONTOGLOSSUM WARNHAMENSE. 
N the accompanying illustration of Odontoglossum warnhamense the 
characters of the two specific parents are clearly visible. This hybrid 
is the result of crossing O. Hallii with O. Pescatorei, and was first raised 
in the collection of C. J. Lucas, Esq., Warnham Court, Sussex, where it 
flowered in 1905. The segments are ivory-white, the sepals blotched with 
chocolate-brown, the petals spotted with similar colour, while the labellum 
is white, as so often happens with hybrids of O. Pescatorei. The spiny 
ODONTOGLOSSUM WARNHAMENSE, 
crest at the base of the labellum is derived from:O. Hallii. Although large, 
and possessing a decorative habit, more especially so when the plant is 
well cultivated, for then the spikes carry many flowers, this hybrid forms a 
useful addition to the Cool-house section. Odontoglossums are easily 
cultivated, and require a cool and moist atmosphere in the summer with a 
minimum of 45-50 degrees in winter. The variety of hybrids is now so great 
that a continuous succession of bloom may be obtained throughout the whole 
year, and if Odontiodas be included the colours cover a very wide range.
