The anthers are united in a ring round the style just as in 
Erica Wilmorei (?) described by Trelease (Macleod, No. 546). 
Erica baccans, L . 
The corolla is practically urceolate, but the closely 
appressed sepals are so folded inwards that they divide 
the interior into four tubular canals. The processes of the 
anthers (both of one anther and one from each of its neigh- 
bours) project into these cavities, and, as they are remarkably 
broad and long, occupy almost the whole space ; when these 
are touched by an insect’s head and proboscis, they cause a 
rotation of the anther on its filament, and the insect will thus 
receive a shower of pollen from three of the anthers. This is 
a further development of the simple type of E. carnea (Muller, 
No. 592) and E. tetralix (Muller, No. 633).

The stamens and style protrude from the mouth of the 
corolla, but the style being longest must first touch an insect’s 
head. I saw a large fly busily visiting this flower, and 
plunging head and thorax into the corolla ; also numerous 
small Diptera and Coleoptera.

The flowers are white with a slight yellowish tinge, and 
are almost three inches in diameter. The corolla-tube (about 
one inch long) is peculiarly twisted, just as if it had been made 
to turn through 90° round its own axis ; in consequence of 
this twisting (which occurs pretty late in development, for 
there is no torsion in young buds) the inside of the corolla- 
tube is hollowed out into five spirally running grooves, each 
of which opens to the outside above by a circular aperture 
between the thickened insertions of the stamens. The anthers 
are almost sessile and very horny in texture ; they are all 
in contact at their upper extremity, and form a small cone 
which projects out of the throat of the corolla ; each pair of
