this is the only way in which it can be grown to perfection.” The flowers 
are two inches across, white stained with amethyst-purple at the tips of the 
segments, the lip prettily fringed and with two orange-yellow blotches on 
the disc. 
D. Falconeri was named in compliment to Dr. Falconer, for some years 
Director of the Calcutta Botanic Gardens. It first appeared in English 
gardens in 1856, whena plant said to have been imported along with others 
from the mountains of Bhotan flowered in the collection of Mr. Geo. Reid, 
at Burnham, Somerset. The stems are slender, of various lengths, and will 
not stand severe shrivelling. A coloured plate is given in Williams’ Orchid 
Album (vol. vi., t. 257). where it is remarked that ‘‘some of the finest 
specimens we have seen were grown for several years by Mr. Swan, when 
gardener to W. Leach, Esq., Fallowtield, Manchester. They were 
cultivated in pots or baskets, and a grand sight they presented with their 
brightly coloured flowers.” Messrs. Veitch, in their Orchid Manual, state 
that D. Falconeri succeeds best attached to a block of wood or tree-fern 
suspended near the roof glass of the East India house. When the season’s 
growth is completed it may be removed to a cooler house, and kept there 
during the winter months, during which time it should be dipped or 
syringed once a week, or so often as is sufficient to prevent an excessive 
shrivelling of the plant. The flowers are two or three inches across, white, 
tinged with pale rose, and with a rich amethyst-purple colour at the tips of 
the segments ; the disc of the lip is rich maroon-purple with a bright orange 
blotch on each side. 
D. chrysotoxum is widely distributed over the plains and mountains of 
Lower Burmah.. The specific name, literally The Golden Arch, is rather 
fanciful, and probably refers to the arching racemes of yellow flowers. The 
bulbs are usually club-shaped, but sometimes spindle-shaped. The drooping | 
racemes are produced from near the top of the stems and carry rich golden- 
yellow flowers, with the disc on the lip orange-yellow. 
D. chrysanthum has slender stems which often extend toa length of 
six or seven feet. It is a native of the hot valleys of the lower Himalayan 
zone, whence it was introduced into the Botanic Garden at Calcutta by Dr. 
Wallich, who brought it to England in 1828. A remarkable specimen of 
this handsome species was at one time in the celebrated collection of the 
late Sir Trevor Lawrence. It was grown in a teak basket, suspended close 
to the glass near the ridge of the East Indiahouse. In September, 1884, the 
flowering stems, upwards of fifty in number, were covered with golden 
flowers, and presented one of the most gorgeous of Orchid displays. The 
flowers are borne in racemes of about six, produced from the current year’s 
growth, while the leaves are still green, and are of wax-like texture, bright 
orange-yellow with two maroon spots on the lip.
