Shrubs with opposite, simple, entire, exstipulate leaves. Flowers solitary, axillary, with the numerous sepals and petals confounded, in several rows, all united below into a fleshy tube or cup. Stamens indefinite, perigynous, with adnate, ex-trorse anthers. Seeds with convolute cotyledons, otherwise as in the tribe Rosidae

The order consists of but 2 genera, Calycanthus. American, and Chimonanthus of Japan. The species are probably but 3. The flowers are highly aromatic, and the same quality resides in the bark.

a flower; from the character.) Lobes of the calyx imbricated in many rows, lanceolate, somewhat coriaceous and fleshy, colored; stamens unequal, about 12, outer ones fertile; anthers extrorse; pistils few or many, inclosed in the calyx tube, fruit many times larger than that of the rose, loosely enclosing the large achenia. - The bark and lvs. exhale the odor of camphor. Fls. of a lurid purple.

C. floridus L. Lvs. oval, mostly acute or acuminate, tomentous beneath; branches spreading; fls. nearly sessile. - Fertile soils, along streams, Va. and all the S. States.
