THE ORCHID REVIEW. 
[August, ic 
produce a pendulous raceme of about ten fleshy flowers, which turn up in 
sub-erect position from the point of attachment to the rachis. Flowers 
light yellowish, spotted with brown, which becomes purplish at the apex of 
the petals and lip. Allied to C. Devonianum, although Sir Joseph Hooker, 
in describing it, remarked that it does not much resemble a Cymbidium. 
Bulbophyllum macranthum.— A well-cultivated plant of this singular 
species was exhibited by Messrs Stuart Low & Co., at the recent Holland 
House Show. The flowers are so flat that they seem as if they had been 
pressed between paper. In the centre they are pale yellow, but the outer 
area is much mottled with dark chocolate-purple. It is figured in the 
Botanical Register for 1844, t. 13., where it is said to have been imported 
by Messrs. Loddiges from Singapore, and to be closely allied to both B. 
Leopardinum and r B. affine. Some idea of the cultural method then 
adopted may be gathered from the accompanying note, which states: 
“ Like the rest of the genus it succeeds best when tied to a block of wood, 
and suspended to a rafter in a moist stove. If the wood is charred enough 
to burn off the bark the block will be found to answer the purpose much 
bette;r, and all insecl^that,harbour it will be destroyed. In summer the 
plant should receive water twice a day at least, and the temperature should 
be kept about 80 degs. by day, and 68 degs. at night.” 
Dissociation of Specific Characters.— Messrs. Julius Roehrs Co., 
Rutherford, N.J., U.S.A., have forwarded an interesting photograph of a 
Cattleya carrying a spike of three flowers, one of which represents C. aurea, 
another shows C. Hardyana, while the third is C. Dowiana. When this 
plant bloomed two years later it again pioduced a spike of three flowers, 
all of which turned out to be C. Hardyana, with yellow sepals and petals ; 
a second photograph verifies this event. In reality we have here a natural 
hybrid between the two species C. Warscewiczii and C. aurea, and known 
as C. Hardyana. It is, however, the first mentioned photograph that is of 
biological interest, for it represents this hybrid with its component parts in a 
state of unstable equilibrium; •Dissociation of specific characters has taken 
place. Another point of interest is that while one might expect C. aurea to 
appear, it is difficult to account for the presence of C. Dowiana, which is not 
a parent of the natural form of C. Hardyana. Whether we regard the C. 
aurea as a geographical form of C. Dowiana, or vice versa, there is no doubt 
that the two are very closely related. The foregoing recalls a remarkable 
spike of C. aurea that flowered in Sir George Holford’s collection in Septem¬ 
ber, 1900. Of the three flowers produced on a single spike, one had the lip 
veined throughout, except at the margin, the second had a yellow disc, and 
the third a darker middle area that partially obliterated the yellow veining.
