This species is not common on the Cape peninsula, but it is 
widely distributed, and extends at least as far as Algoa Bay, 
whence I have had examples from Mr. Hallack differing only 
by being more robust, with larger and more pointed petals. 
In the genus the following species— D. secunda, Sw., D. filicor- 
nis, Thunb., D. patens, Thunb., D. reflexa, Reichb. f. (though I 
do not think this can be separated from D. filicornis), with the 
present species, and perhaps some others unknown to me, consti- 
tute a very naiural section. They are characterized by a dorsal 
sepal expanded (not galeate), saccate, or merely concave, and a 
suberect anther. They also possess a remarkable process of the 
rostellum of an expanded petaloid character, extending from the 
arms backward and under tlie anther, and reaching generally 
about halfway up its length. The form of the dorsal sepal, cha- 
racteristic of this section, is much less common than the galeate; 
and as it somewhat resembles the vexillum of many Papilionace®, 
I propose to employ the term Vewillata for the section.
