246 THE ORCHID REVIEW. [SEPTEMBER, 1960. 
_ flowers (now known to be males), and a seed capsule, the significance of 
which will presently be apparent. Bateman remarked upon the huge size 
of the capsule and the innumerable quantity and minuteness of the seed. 
In the following year C. chlorochilon was described by Klotzsch, from 
a plant which had been sent from Caracas by Moritz, and which flowered at 
Berlin. This species was afterwards confused with C. ventricosum. 
In 1840 C. maculatum was described by Lindley, from a plant which 
flowered in the collection of Mr. Barker, of Birmingham, and which was 
thought to be a native of Mexico, though it was added that a collector of 
Messrs. Hugh Low & Co. had found the plant in La Guayra, and the 
Venezuelan habitat is now known to be correct. ) 
In July, 1842, Bateman figured C. Egertonianum, whose remarkable 
history is reproduced verbatim, but as this has appeared in these pages, 
together with a reproduction of the original and a recent figure (O.R., xvi. 
pp. 296, 297, fig. 38, 39), we need not repeat it. 
A year later Lindley published a very interesting figure, which ought to 
throw further light on the subject. It represented an inflorescence which 
appeared in the collection of R. S. Holford, Esq,, of Westonbirt, Tetbury, 
and which was described as showing two purple flowers of C. Egertonianum, 
one green flower which Lindley called ‘‘nearly C. ventricosum,” and two 
flowers in a transition state so far as the colour and shape of the flowers are 
concerned. The plant was exhibited at a meeting of the Horticultural 
Society. Lindley was unable to offer any explanation of the significance of 
the phenomenon, merely remarking that with such cases all ideas of species 
and stability of structure in the vegetable kingdom were shaken to their 
foundation. 
Other species were successively described, and in 1852 Lindley gave an 
enumeration of the so-called species of Cycnoches, nine in number, 
remarking that five of them had not been known to sport. Two of them 
are now excluded from the genus. 
In the same year C. Warscewiczii was described by Reichenbach, on 
what, from internal evidence and from a flower preserved in Lindley’s 
Herbarium, is now known to be a female of some species of Cycnoches, and 
distinct from that afterwards figured under the same name. 
The discovery of sexuality in the allied genus Catasetum threw the first 
ray of light upon the subject, but the matter was never cleared up, 
Darwin merely remarking that “from the analagous differences in the 
labellum of the sexes in Catasetum we may believe that we here see the 
male, female, and hermaphrodite forms of Cycnoches.” It is now known 
that the third sex does not exist in either genus. 
In 1879 another remarkable example appeared, and was exhibited at a 
meeting of the Royal Horticultural Society by Mr. W. Bull, of Chelsea,
