Description

Woody plants, mostly shrubs or trees, sometimes scandent; branches and branchlets tetragonal or subterete, glabrous or variously pubescent. Leaves This content downloaded from 192.104.39.2 on Thu, 9 May 2013 15:26:14 PMAll use subject to JSTOR Terms and Conditions102 ANNALS OF THE MISSOURI BOTANICAL GARDEN [VOL. 60 simple, usually decussate-opposite, rarely subopposite or ternate, deciduous, ex- stipulate, mostly petiolate, glabrous or variously pubescent, entire or dentate. Inflorescences cymose, determinate, the cymes often paniculate, umbellate, capitate, reduced to few or solitary flowers, axillary or terminal. Flowers actino- morphic, hypogynous, hermaphroditic but usually conspicuously declinous; calyx gamosepalous, more or less campanulate, cyathiform or tubular, apically truncate and entire or 4- or 5-toothed or -lobed, accrescent, greatly incrassate and indurated in fruit; corolla gamopetalous, infundibular or hypocrateriform, mostly white or yellow, the tube cylindric, the limb equally 4- or 5-parted, the lobes imbricate in prefloration; stamens 4 or 5, equal, isomorphic, inserted below the mouth of the corolla-tube, included or exserted, alternate with the corolla-lobes, the filaments mostly filiform, the anthers often reduced but sometimes still polleniferous in pistillate flowers; pistil one, the style terminal or subterminal, single, capillary, mostly glabrous, the stigma bifid, its branches elongate and awl-shaped, the ovary superior, perfectly or imperfectly 4-celled, each cell 1-ovulate, the ovules lateral or sub-apical, hemianatropous. Fruit drupaceous, mostly fleshy, globose or sub- globose, (1-3-)4-seeded, sometimes fewer by abortion; seeds without endosperm.

Distribution
|
A complex genus of about 175 species and infraspecific taxa of subtropical and tropical America. Aegiphila ranges from Cuba and Mexico through the West Indies and Central America to Peru, and northern Argentina. One species is introduced in south Florida. Several species are sometimes cultivated as specimen plants. The Central American forms need further study, preferably in the field.
