CoLONrtr. Ma l l ' s Odontoglossum is looked upon as the finest and noblest of a numerous and puzzling group of
Odontoglossums known among Orchid growers as the hiteo-purpureum section. There is a conspicuous similarity of
growth and flower in the species comprising this group, though there is a vast difference between the finest, such as
O. I lallii, and the inferior forms, which are usually undecidcd in colour and poor in form. The flowers of all exhibit a
great diversity in their
sisecies to the otlicr.
O. Hallii isa na
have come. It was kii
subsequently Dr. Jamc:
of it he pronoimccd it ti
possess and n
larkings, but a prevailing tint of chestnut-brown and yellow n s from o t end of the chain of
•e of Ecuador, that delightful Orchid region whence so many of our cool Orchid house treasures
i-n to botanists long before living plants reached Europe. Colonel Hall first discovered it, and
1 met with it in othei" parts of the Kcuadorian Andes. When Lindley received dried s|)edmens
)ea most beautiful plant, and this encomium was sufficient to set Orchid growers longing to
o import it. At length Wallis sent living plants of it in 1865 to Mr, I.inden. During the time
that has since elap.sed it has not been imported largely, as it is a most difficult plant to bring to Europe, the plants being
so liable to perish at Guayaquil, tlie port whence collcctcd plants are shipped, the heat there being often as high as
120 deg. T^, and this heat prevails during the journey by rail across the isthmus of Panama. Among the largest
importations have been those sent home by Wallis, who was particularly succcssful in obtaining it.
There are several forms of O. Hallii in collections, some being much superior to others, and a few are so distinct
as lo be worthy of varietal names. The typical form has large bold flowers, with broad greenisli-yellow sepals heavily
blotched with brown, and with a large white labellum. This is called in gardens Icucoglossuni in order lo distinguish it
from ihc yollo«' lipped variety, xanthogiossum, the subject of our present plate. There is also a variety named
magnificum, the flowers of which arc much larger than those of the type and with richer colours.
The culturo of this Odontoglossum is similar to that recommended for O. cri.spum, but the imported plants are not
easily established, the pseuilo-bulbs being so soft and fleshy. It is a good plan to hang the bulbs heads downwards
until they show signs of rooting, for then the bulbs are not so liable to rot. The plants should be potted immediately
roots are seen protruding from the bases of the bulbs, and water should be given gradually. This Orchid must be kept
growing all the year round, and only during the time it is in bloom should it be kept a little drier. A cool and moist
atmosphere, abundance of light (but not direct sunlight), and thorough ventilation, i
It of this fine specics.
