240 THE ORCHID REVIEW. 
CYPRIPEDIUM HYBRIDIZATION. 
With respect to the interesting question raised at page 201, as to 
whether the influence of one parent of a hybrid may not sometimes be 
almost, if not quite, obliterated in the offspring, a case has occurred in the 
collection of C. Winn, Esq., The Uplands, Selly Hill, Birmingham, which 
it may be interesting to record. Mr. Winn crossed a flower of Cypripedium 
venustum with the pollen of C. concolor, and a batch of seedlings was the 
result. In due time they reached the flowering stage, but to his disappoint- 
ment every plant proved to be poor forms of C. venustum. What may be 
the explanation of this we cannot say, but the facts were given to us by Mr. 
Winn himself, and to some extent they confirm Mr. Young’s experience 
with C. barbatum and C. niveum. Then there is the curious case of C. 
x Corndeanii mentioned at p. 215. Perhaps others of our readers may 
have had similar experiences, in which case it would be interesting to place 
them on record. 
CORYANTHES MACULATA VAR. VITRINA. 
A remarkable variety of the above variable species has flowered with 
Messrs. F. Sander & Co., of St. Albans, in which the markings have 
entirely vanished, and thus it may be considered as an albino of the species, 
It was imported from Central America. The sepals and petals are light 
greenish-yellow, the hood and column a little paler yellow, and the lip a 
semi-transparent shade of very pale yellow, with a slight dash of palest 
green. There is an almost glassy appearance about the flower, which 
renders the above name very appropriate. R. A. R. 
DENDROBIUM SPECIOSISSIMUM. 
It is interesting to note that this remarkable species, whose history was 
given at page 119, has now flowered in cultivation. A small plant, bearing 
one about half-developed flower, was exhibited by Messrs. F. Sander & Co. 
at the Royal Horticultural Society’s meeting on July gth, and received a 
Botanical Certificate. On July 23rd it was again exhibited, both by this 
firm and also by Messrs. Hugh Low & Co., and being in better condition 
received an Award of Merit. The flowers are white, and bear a considerable 
resemblance to those of D. formosum, though they are quite different in the 
large rounded front lobe of the lip, and in the markings inside the spur. 
There is a broad yellow line on the disc, which becomes rosy-red_ behind, 
while the base of the spur inside is yellow, margined all round with a rich 
crimson line where it joins the white. It has not, however, yet attained its 
normal development, and if it proves at all amenable to cultivation we may 
hope to see it hereafter in something like its true character.
