way between their base and apex, the style is partite, and is de- 
scribed as bipartite, tripartite, quadripartite, &c., according to 
the number of partitions. 
Form and Surface of the Style.—In form the style is gene- 
rally more or less cylindrical ; and either tapering from the base 
to the apex, as is more frequently the case, or becoming en- 
larged as it proceeds upwards. At other times the style is fili- 
form, or more or less thickened, or angular ; and rarely thin, 
coloured, and flattened like a petal, as in the species of Canna 
and Iris (fig. 643), when it is said to be petaloid. 
The surface of the style may be either smooth, or covered in 
various ways with glands or hairs. These hairs when situated 
on the style frequently serve the purpose of collecting the pollen

as it is discharged from the anther, and are hence termed col- 
lecting hairs. The collecting hairs on the style of the species of 
Campanula (figs. 158 and 159) are retractile ; they have been 
already described under the head of Hairs (page 68). In the 
Compositze the surface of the style is also more or less covered 
with stiff collecting hairs (fig. 645, pc), and as the style is de- 
veloped later than the stamens, it is at first shorter than these 
organs ; but as growth proceeds, it breaks through the adhering 
anthers, and thus the hairs on its surface come in contact with 
the pollen and become covered with it. In some of the allied 
orders to the Compositz, the hairs form a little ring below the
