236 THE. ORCHID REVIEW, [AUGUST, 1922- 
Colombian O. hastilabium, and thus links up two sections of the genus. 
Both parents usually bear numerous flowers on tall, branched spikes. In O. 
Eurydice, which was raised by Messrs. Charlesworth & Co., the ground 
colour is cream-white, the spotting red-brown, and the crest on the 
labellum yellow. 
ORCHIDS OF YUNNAN AND NORTHERN BURMA. 
UMEROUS Orchids collected chiefly in the temperate and sub-alpine 
areas of S.W. Yunnan and the Burmo-Chinese frontier are described 
by Professor W. W. Smith, M.A., in a recent issue of ‘‘ Notes from the 
Royal Botanic Garden, Edinburgh.” The greater part of the material was 
collected by Mr. George Forrest and the remainder by Capt. Kingdon 
Ward and the late Mr. Reginald Farrer. The number of species added to 
the flora of the area—whether new species or new records—is considerable. 
It is stated that many well-known Burmese Orchids are represented in this 
corner of China, and are not found further north or east. Near Tengyueh, 
at an elevation of some 5,000 feet, a huge lava bed, overgrown by a dense 
matted jungle of shrubs and climbers, was found by Forrest to be rich in 
Orchidez of pronounced Burmese affinity. Professor Smith says that what 
has been found on the Burmese side of the frontier can represent only a 
tithe of the alpine Orchid flora of the area. The Orchids obtained by 
Forrest during his expeditions in the years 1904-05, were dealt with by 
Mr. Rolfe (Notes R.B.G. Edin., viii., pp. 19-29), and those resulting from 
the explorations of the year 1906, were identified and described by Dr. 
Schlechter in the same publication during 1912 (vol. v., pp. 93-113). The 
present paper, which deals with the collections made during the years 1912- 
1914 and 1917-1919, includes over eighty species. 
Bulbophyllum hyacinthiodorum is described as a new species with 
flowers pure white or slightly tinged with green and having a strong 
fragrance identical with that of Roman hyacinths. Calanthe Wardii is a 
novelty which can be well distinguished from its allies by the twin axe- 
headed shape of the labellum. Coelogyne Sanderz has typically three 
parallel hairy keels on the labellum, but in the Yunnan specimen of Forrest 
there are only two. Dendrobium Wardianum, originally introduced from 
Assam in 1856, and subsequently from Burma in 1875, is now stated to be 
also found in China. A new species described by Professor Smith as 
Listera unguiculata is well distinguished by the remarkable labellum 
shaped like a pair of pincers. Vanda Bensoni has not previously been 
recorded from China, and of Zeuxine inverta it is remarked, ‘‘A very 
peculiar plant. The flowers are resupinate—the labellum forming a kind 
of hood over the flower. The form of the labellum is quite that of 
Zeuxine and not of Hetzeria, which has a superior lip.”
