THE COROLLA, The leaves of which the corolla consists, or petals^ are,as a rule, much more delicate than- those of the calyx, andare usually coloured, white or some bright colour incontradistinction to green. The colour of the corolla is,however, of subordinate importance, and is often variable inthe same plant. The corolla of Fulmonaria, for example,is red when it first opens, and afterwards becomes violet[that of Cobcea scandens changes gradually from pale-greento purple], while that of Hibiscus abelmoschus is white in themorning, pale red by mid-day, and rose-red in the evening. ^ *
