272 THE ORCHID REVIEW. [SEPTEMBER, £906. 
and lip are fairly similar in the two sexes, though there are slight differences 
in sizeand texture. In the sexual organs the differences are very marked. 
In the male the column is very long and slender, arched like the neck of a 
swan, and bearing the anther at the summit, without a stigma or column 
wings, while the ovary is reduced to a simple pedicel. In the female the 
column is very short and stout, with a normal stigma, protected by a pair 
of triangular, fleshy wings, without an anther, while the pedicel is much 
stouter than in the male, from the fact that it contains the incipient ovary. 
In the section Heteranthe the female is shaped as in Eucycnoches, but the 
male is usually very much smaller, the sepals and petals much thinner in 
texture, soon becoming recurved after expansion, and in some cases 
markedly different in colour, while the lip is reduced to a small, usually 
rounded disc, margined with clavate teeth. Correlated with the smaller 
size of the males we find a greatly increased number of flowers, which are . 
borne in a long pendulous raceme. These characters are shown in the four 
figures which represent C. ventricosum and C. Egertonianum, the female of 
the former being from a flower which appeared in the collection of Sir Philip 
Egerton, in 1849, and. of the latter from one which appeared at Kew 
in 1895. se? 
Six species of Eucycnoches are enumerated, namely C. Loddigesii, 
Lindl., C. ventricosum, Batem., C. chlorochilon, Klotzsch, C.. Lehmannii, 
Rchb. f., C. Haagei, Rodr., and C. versicolor, Rchb. f., of the three latter 
the males only being known. Of Heteranthz there are ten species, namely 
C. Egertonianum, Batem., C. pentadactylon, Lindl., C. stelliferum, Lodd., 
C. aureum, Lindl., C. Rossianum, Rolfe, C. densiflorum, Rolfe, C. 
maculatum, Lindl., C. Dianz, Rchb. f., C. glanduliferum, Rich. & Gal., and 
C. peruvianum, Rolfe, of the four latter the males only being known. Thus 
in nine out of the sixteen species both sexes are known. A complete list of 
figures and references is given under each species, and the synonymy shows 
that there has been a good deal of confusion, though in only one case does 
it affect the nomenclature, the species usually known as C. Warscewiczil 
now appearing as C. stelliferum, Lodd., which arises from the fact that it is 
not the original C. Warscéwiczii, Kchb. f., which is believed to be the 
female of C. aureum Lindl. 
Two females of doubtful identity are enumerated, one which appeared 
with Messrs. Sander, in 1895, and is said to have been imported with C. 
peruvianum, and may therefore be the female of that species, and another 
which flowered with Messrs. Charlesworth & Co., in 1903, and is said to 
have been imported with C. chlorochilon, which is suggested as the 
unknown female of C. maculatum. 
It is to be hoped that the increased attention now being given to these 
interesting plants, may help to complete the history of the genus,
