Podocarpus (Greek, pous, podos, foot, and karpos, fruit; alluding to the conspicuous fleshy footstalks of most species). Including Nageia, Prumnopitys and Stachycarpus. Taxaceae. Ornamental woody plants grown for their evergreen foliage.
Resinous evergreen trees, rarely shrubs: lvs. alternate, sometimes opposite or 2-ranked, sessile or short-stalked, linear to elliptic, entire: fls. monoecious or dioecious, axillary or subterminal, solitary or in spikes; the staminate catkin-like, consisting of spirally disposed, 2- celled anthers; the pistillate consisting of a scale inclosing the ovule, with several bracts at the base, which become usually much thickened at maturity, and form a fleshy receptacle bearing at the top the globular or ovoid drupe- or nutlike seed: cotyledons 2.—Fifty-five species, chiefly in tropical and subtropical mountains of S. Amer., W. India, Asia, Afr., and Austral. Some species with the fls. in spikes and the fr. without fleshy receptacle are separated by some botanists as Prumnopitys (Stachycarpus). Many species are valuable timber trees in their native countries, and the fleshy seed-stalks of some are eaten.
The podocarpuses are evergreen often tall trees with usually narrow, rarely elliptic, dense foliage, small flowers, the staminate yellow, the pistillate greenish and inconspicuous, and with rather small, berry-like fruit borne on usually much thickened fleshy footstalks of dark purple or purplish violet color. They are but rarely cultivated in this country and only adapted for the southern states and California, except P. alpina, which is the hardiest and may probably thrive as far north as Philadelphia, or even farther. They grow best in well-drained loamy soil. In the North they are sometimes grown as pot-plants in greenhouses on account of their handsome foliage; a sandy compost of loam and peat will suit the potted plants. Propagation is by seeds or by cuttings of almost ripened wood under glass; they are also sometimes grafted on any of the species which can be had in quantity.
