58 MR. J. C. WILLIS ON THE 
style at the base of the flower and are glabrous ; they bear the 
usual large versatile anthers. The appendages at the base of 
the stamens resemble those of P. Campanularia, but are hairy. 
Honey is secreted as usual. The ovary and style are hairy; the 
style is not, however, so_ deeply bifid as in the species last 
described. 
The whole mechanism very closely resembles that of P. Cam- 
panularia, except that the lobes of the style are closely pressed 
against one another in the early stage, and only separate when 
the style has grown up to the level of the anthers. The honey is 
perhaps better protected owing to the closeness of the stamens 
to the style at the base of the tube and the hairiness of the 
staminal appendages. 
P. Parryi.—In general habit this species also resembles P. Cam- 
panularia, but the flowers are smaller. The calyx and peduncle 
are as usual hispid and glandular. The corolla is funnel-shaped, 
with expanded limb, and is provided on the outside with scattered 
glandular hairs, thus acting probably as a further protection 
against unbidden guests. Its total depth is about 13 mm. and 
width 23 mm., the width of the throat being about 9mm. Age 
causes no appreciable increase in these measurements. The 
tube is contracted by five longitudinal furrows, but they are 
alternate with the stamens, not opposite to them asin P. Campan- 
ularia. They are coloured white, but are of no great depth in 
proportion to the diameter of the tube. The general colour of 
the corolla is a deep azure-blue. The stamens are long, project- 
ing 5-10 mm. beyond the corolla, and bear large versatile anthers ; 
they are thinly covered with long upward-pointing hairs, and 
bear glabrous basal appendages like those in P. Campanularia. 
Honey is secreted as usual. ‘The ovary and style are hairy; the 
latter is more deeply bifid than in P. Whitlavia. 
The mechanism is much the same as that of P. Campanu- 
laria. In the early stage the style is included in the corolla; 
its length, from the top of the ovary, is 10 mm. It lengthens 
afterwards to 19 mm. and overtops the stamens. Its branches 
are usually close together at first, though not actually adherent. 
The flower is visited, in Cambridge, principally by Apide and 
Syrpbide, whose mode of action is the same as already described 
for P. Campanularia. 
The peculiar mode of dehiscence of the anther in this genus 
was observed carefully in this species. The anther is oblong in
