on the inner side, which must go in advance when the style emerges 
from the carina, is formed of a single row of stiff hairs, slanting 
upwards in the middle line. The brush on the outside consists of 
a single row of hairs at its lower end only, and farther upwards it 
broadens out until immediately below the stigma it more than half 
surrounds the style; its hairs, which in the lower part are stiff and 
slanting upwards, diverge more and more, until close beneath the — 
stigma the truncated end of the brush forms a shallow saucer- 
shaped hollow (p, 5,6). In the bud the two brushes lie, surrounded 
by all the anthers (p, 7), im an expanded part of the apex of the 
carina (f, 3, 4). The anthers dehisce when the petals are nearly
