360 THE ORCHID REVIEW. 
CYMBIDIUM TRACYANUM. 
A short time ago Mr. H. A. Tracy, of Twickenham, with whom the 
above handsome plant originally appeared, asked me if I could throw any 
light on its origin. Was it a species or a natural hybrid? The original 
plant, it may be remembered, flowered quite unexpectedly in December, 
1890, and being exhibited at a meeting of the Royal Horticultural Society, 
received a First-class Certificate. A few days later it was sold at Messrs. 
Protheroe and Morris’s sale rooms for 75 guineas. Two or three other 
plants have since appeared, though none equal to the original, I believe, in 
point of size. A Cymbidium, said to have been received from Upper 
Burma, has just produced a ten-flowered raceme, in the collection of W. J. 
Woodhead, Esq., Elton, Maghull, Liverpool, and proves to be a form of 
the same, though with flowers not very much larger than C. giganteum. 
It would be interesting to know more about the habitat of this curious 
plant. Have the other plants come from Upper Burma? And is it a local 
form, or does it grow with anything else, as C. giganteum and C. grandi- 
florum (Hookerianum), for example? It is so intermediate between the two 
species just named that if only it were known to occur with them one. 
would think it might be a natural hybrid between them. The flowers are 
striped with red-brown, as in the former, but the lip is more three-lobed, 
less hairy, and the keels wider apart, all of which characters place it near 
C. grandiflorum. It would be interesting to complete the history of this 
fine plant, but the necessary materials are not yet forthcoming. At present 
the facts point in the direction of its being a distinct geographical form, 
for we have not yét any evidence of the occurrence of either C. giganteum 
or C. Hookerianum in Upper Burma.

ONCIDIUM GEERTIANUM. 
The identity of this pretty little species seems to have been quite lost, 
since Lindley wrongly referred it as a synonym of his O. nebulosum. It 
was originally introduced from Guatemala, and flowered in the collection of 
M. A. Van Geert, of Gand, being figured and described by Prof. Charles 
Morren, in 1848 (Ann. de Gand, iv., p. 55, t. 179). Six years later it was 
again figured and described under the name of O. cesium by Professor 
Reichenbach (Gartenflora, III., p. 75, t. 80) from a plant in the collection of 
Herr Hofrath Kiel, at Leipsic, in November, 1853, its habitat being unknown. 
It occasionally appears among Mexican importations, and is generally 
cultivated in gardens under its later name. It is allied to O. reflexum, 
Lindl., from the same country, but is easily distinguished by its greenish 
sepals and petals, and other characters. Messrs. F. Sander & Co. have 
recently flowered it out of an importation received from Mexico.
