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.
