later the error was discovered, and it was pointed out that not only 
were the two distinct but that they belonged to different sections of 
the genus, which were then named Eucycnoches and Heteranthae 
(Gard. Chron. 1892, xi. p. 205). 
The two sections are distinguished by very marked differences in 
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 Heteranthae the female is shaped

Most of the figures published under this name belong to C. Eger- 
tonianum, Batem., but that of Maund represents C. chlorochilon, 
Klotzsch. The female was received from Sir Philip Egerton m 
1849, and is preserved in Lindley’s Herbarium, but I find no record 
of it at the time, and although it was then thought to be ordinary 
C. ventricosum, the short column might have invited remark.
