Willis and Burkill. — Floivers and 
17, 18, 19, 21, 332 a, 258 b, 339 b.] Common in the district, 
but somewhat past its best flowering season. The female 
form was not observed.

PLUMBAGINACEAE : 17. Statice Limonium L. [Class B, 
Lit. 4, 14, 15, 339 b.] Frequent on the shore of Auchencairn 
bay, but being placed in competition with a much larger 
mass of flowers of Aster (see above) it was practically left 
unvisited. Self-fertilization seemed to occur in some speci- 
mens examined. During the spring tides in August, 1894 , the 
flowers, like those of Aster , were submerged twice daily.

Ericaceae : 18 . Calluna vulgaris Salisb. [Class B, Lit. 
1, 2, 4, 9, 11, 14, 17, 18, 25, and see No. 48 , below.] This 
species abounds in the district, there being numerous moors 
covered with it. It was in full flower when studied. An 
important point, apparently only noticed by one previous 
observer (Kerner), is the anemophily of this plant. It pos- 
sesses the characteristic ‘ loose-pollen 5 mechanism of Erica ; 
but whilst in the latter the flower hangs almost vertically 
downwards and has a deep tubular corolla almost covering 
the stigma and quite covering the anthers, in Calluna the 
flower stands out more nearly horizontally, and has an open
