Tubular, a cylindraceous form spreading little or none at the border, as the calyx of the pink, corolla of the horeysuckle. It is often a little curved. Tubular flowers are common in the Compositse, as the thistle, sunflo'.ver, when they are often- associated with 482.

The notches at the end plainly indicate the number of united petals composing it, as also do the paral- lel, longitudinal seams. 483.

In the labiate corolla three petals unite more or less to form the lower lip, and two to form the upper. In the calyx, when bilabiate, this rule is reversed, accord-.
