SMALL PERIWINKLE 73 
would become smeared with a sticky substance to which pollen would 
adhere, and this would be transferred in the next flower to the stig- 
matic disk. The flowers are conspicuous. There is abundant honey, 
which attracts numerous insects when it is fine. The tube of the 
corolla is 11 mm. long, but enlarged so that insects can insert their 
heads as far as the anther-hairs. The two yellow nectaries at the 
base of the ovary are 8 mm. below, and protected from rain by the 
hairs at the entrance.

SMALL PERIWINKLE (Vinca minor, L.) 
The stamens are bent, attached half-way up the tube. The anthers 
project above the stigma, which is conical, enlarged above with a flat 
plate at the top, sticky along the rim, hairy above. The pollen falls 
above the latter. Insects sipping the honey carry off the pollen to 
fresh stigmas. 
The Lesser Periwinkle is visited by Bomdus, Anthophora, Osmia, 
Bombylius discolor, Vhysanoptera, Threps. 
The fruit is a follicle, which is rare. It is adapted for dispersal of 
the seeds by the wind, the seeds being compressed, winged, and pro- 
vided with hairs. 
This plant is a humus-loving plant, growing in a humus soil, in 
or near woods. 
Two moths, Daphnia neriz (Oleander Hawk-moth), Clouded 
Bordered Brindle (77iphena janthina), feed upon it.
