274 THE ORCHID REVIEW. 
Afterwards, it was procured in a living state by Richard Harrison, Esq., of 
Liverpool, in whose collection it flowered for the first time in cultivation in 
March, 1835, when it was figured in the Botanical Register (t. 1699.). It 
has since been found in Guatemala, the Isthmus of Panama, the province 
of Santa Martha, the Rio Magdalena district, and in the Island of Trinidad, 
so that it is, evidently, widely diffused in Central America. In the Rio 
Magdalena district, it was collected by Weir, when travelling for the 
Horticultural Society, and afterwards by Burke, for Messrs. James Veitch 
and Sons. The latter found it “growing on trees overhanging streams 
flowing into the Magdalena, at 500-1000 ft. elevation, in partial shade.” 
The species is variable in size in all its parts, and in 1855 Lindley 
remarked that there were two varieties in cultivation differing in the size of 
the flowers (Fol. Orch., Oncid., p. 28). The finest form was afterwards figured 
under the name of O. ampliatum majus (FI. des Serres, t. 2140-1), in 1874. 
In this form, the flowers sometimes exceed 14 inches in diameter. A 
particularly fine example of it which flowered in the collection of Joseph 
Broome, Esq., Sunny Hill, Llandudno, was. figured from a photograph in 
1895 (Gard. Chron., 1895, xvii., Ppp- 172, 173, fig. 26). 
CYCNOCHES CHLOROCHILON. 
CYCNOCHES CHLOROCHILON seems to be the most popular species of this 
remarkable genus, and of late years good examples of it are frequently met 
with. It is interesting to note that out of three plants which have recently 
bloomed in the Kew collection one has produced a female flower, and it 
may be remembered that Messrs. Hugh Low & Co. exhibited a good plant 
bearing three females at a meeting of the Royal Horticultural Society in 
November, 1899. Unlike many others in the genus, the two sexes do not 
differ much, except that the female flower has a stout ovary and a short, 
stout column, with a triangular wing on either side of the stigma, but no 
anther. The perianth, however, is slightly larger and more fleshy, and the 
number of flowers on each inflorescence is reduced, ranging from one to 
three. The first female flower that I saw, and the first that I can find 
recorded, appeared in the collection of M. Houzeau de Lehaie, of Hyon, 
near Mons, Belgium, in 1891, and is specially interesting because it 
enabled the mystery of the two sexes in the genus to be cleared up- 
The species is illustrated in Reichenbachia (ser. 2, i, t. 39), and figures 
of both sexes are given in the text (p- 83), where I also outlined the 
characters of the two distinct sections of the genus. A glance at these 
figures will enable anyone who may not have seen living flowers of both 
sexes to realize the difference between them.
