who received a Botanical Certificate for it. It was called C. Warscewiczii, 
and was described and figured in the Gardeners’ Chronicle, as a curious 
Orchid with green flowers borne on two separate spikes, those on one spike 
being much larger and totally different in appearance from those on the 
other—so much so that seen separately they would be taken as belonging to 
different genera. It was also remarked that the explanation of this and of 
similar appearances in Catasetum was that the different flowers represented 
the male and female flowers of the species. 
In 1889 a plant of Cycnoches pentadactylon in the collection of Mr. E. 
Gotto, The Logs, Hampstead Heath, produced flowers of both sexes. 
Two years later anew species was described from materials of both sexes 
which appeared in the collection of Mr. H. J. Ross, of Florence, under the 
name of C. Rossianum. It had been purchased under the name of C. 
Warscewiczii, and had flowered on various occasions before January, 1889, 
when a female flower was produced. This female flower was then thought 
to belong to a totally different species, but the subsequent production of 
male flowers and the discovery that there was only a single plant of 
Cycnoches in the collection established the identity. 
In 1891 the female of Cycnoches chlorochilon appeared, first in the 
collection of M. Houzeau de Lehaie, Hyon, Mons, Belgium, and afterwards 
on three different plants with Messrs. Sander, at St. Albans. In each of 
these cases the female only was borne by the plant, but shortly afterwards 
both sexes appeared on the same plant in M. Houzeau’s collection. 
By this time it had become increasingly evident that something was 
wrong with Bateman’s figure, which showed two kinds of male flowers on 
the same pseudobulb, and the receipt shortly afterwards of male flowers of 
another species led to the re-examination of all the available materials, 
which showed that an unfortunate mistake had been made, probably through 
the two kinds of flowers not being borne simultaneously, and the earlier 
being restored by the help of a drawing. It was unfortunate that the flowers 
were not preserved, or the mystery might have been cleared up earlier. The 
re-introduction of the species after a long interval supplied the necessary 
confirmation. In the autumn of 1894 a living plant of a Cycnoches was 
sent to Kew from Costa Rica by the late Mr. Ricardo Pfau, which on 
flowering in April of the following year proved to be C. Egertonianum, and 
three months later the female flowers also appeared, and proved to be quite 
different from the green flowers figured by Bateman. 
The circumstances just detailed led toa very curious discovery, namely 
that the flowers depicted by Bateman as produced by the same pseudobulb 
belonged not only to distinct species, but to distinct sections of the genus, 
which are described and illustrated in the paper under notice. In the 
section Eucycnoches, to which C. ventricosum belongs, the sepals, petals
