 Rh sufficient in general to say that a Corolla is regular in opposition to one that is irregular; more especially as some species of a genus may possibly have an equal corolla, others an unequal one.

The most usual shapes of a monopetalous corolla are

campanulata, bell-shaped, as in Campanula, t. 12.

infundibuliformis, funnel-shaped, Pulmonaria, t. 118.

hypocrateriformis, salver-shaped, Primula, t. 4.

rotata, wheel-shaped, that is, salver-shaped with scarcely a tube, Borago, t. 36.

ringens, ringent, irregular and gaping like the mouth of an animal, Lamium, t. 768; called by former botanists labiata, lipped.

personata, personate, irregular and closed by a kind of palate, Antirrhinum, t. 129.

Those of a polypetalous one are

cruciformis, cruciform, regular and like a cross, Dentaria, t. 309, and Cheiranthus, t. 462.

rosacea, rosaceous, spreading like a rose, Dryas, t. 451.
