246 THE ORCHID REVIEW.  (|Sertemper, 1922. 
truly beautiful flowers. The climate of the United States is, generally 
speaking, a little too warm for the majority of Odontoglossums, hence the 
necessity of producing plants that will prove suitable and be of service 
where flowers for decorative purposes are required. M. vexillaria is a 
species that delights in somewhat warmer conditions than those maintained 
in the Odontoglossum house, although the flowers possess the unfortunate 
character of being very fragile, in fact, they are almost useless when 
severed from the plant. The combination of Miltonia and Odontoglossum 
yields hybrids suitable for the United States climate, and the plants give 
spikes of bloom that are far more useful to the floral decorator than any 
species of Miltonia. M. Reezlii is of similar constitution to M. vexillaria, 
although, strange to say, when mated with it the resulting flowers are 
larger than those’of either parent. Many very beautiful Odontonias have 
recently been produced through the use of M. Bleuana. In Odontoglossums 
it is generally the broad petals that possess the attractive points, but in 
Odontonia it is the expansive labellum that at once appeals to the amateur. 
As time goes on, we shall see Odontonias with much broader petals, and it 
is the happy combination of the broad petals of the one genus and the 
expansive labellum of the other that will come into being in the future.

Mittonta WaRSCEWICZII XANTHINA—The varietal name xanthina is 
applied to varieties in which the usual brown and purple markings are 
absent, leaving the flower white with some light yellow marks. As long 
ago as 1881 there was a distinct form of this species in the collection of 
Mr. C. Winn, Selly Hill, Birmingham. It was described by Reichenbach 
as variety ztherea, the sepals and petals being lightest yellow with white 
tips, the lip similar, but bordered and based with lightest mauve-lilac- 
Two years later the variety xanthina appeared in Mr. William Lee’s 
collection at Leatherhead. The sepals and petals were marked with deeper 
yellow, the lip light yellow, but with no purple whatever. In the autump 
of 1901 Messrs. Charlesworth had a similar kind in flower. During recent 
years several beautiful hybrids have been produced by using this variety 1” 
connection with xanthotic Odontoglossums, a well-known example being 
Odontonia Magali Sander alba. Miltonia Warscewiczii was originally 
discovered by Poeppig, in 1830, near Cachiro, in Peru, and was again found 
by Warscewicz, who brought dried specimens to Europe. Gustav Wallis 
sent specimens to Messrs. Linden in 1868, and one of these was exhibited 
at the Royal Horticultural Society in October, 1869. In later years it was 
collected by Burke, for Messrs. Veitch, and was then found growing oF 
small trees and shrubs close to the ground, and on moss-covered stones at 
2000 to 3000 feet elevation, near the Rio Verde, in the Province of 
Antioquia.
