PODACH^NIUM 



PODOCARPUS 



PODACHL/feNIUM (Greek, foot and achene, alluding 

 to the base of the achenes). Composite. Tall shrubs, 

 one of which in southern California is said to attain a 

 height of 30 feet, cultivated chiefly for their large and 

 fragrant leaves. 



Leaves opposite, large and angular-lobed: heads 

 small, disposed in a broad corymbose panicle; fls. with 

 white rays and yellow disk: achenes sparingly pilose. 

 Two or 3 species, Mex. to Colombia. The principal 

 species of Podachsenium, P. eminens, is commonly cult, 

 under the name of Ferdinanda, which is really the old- 

 est generic name, but this name is also used for some 

 species of Zaluzania. The distinguishing feature of 

 Podachaenium is the shape of the achene, which is con- 

 tracted at the base into a 2-winged stipe suggesting the 

 shape of a foot. In the N. and in Eu., they are grown 

 in the warmhouse, but they are quite hardy in the open 

 in the S. The fl.-heads are about 1 in. across, and about 

 20 or more in terminal flat-topped clusters, borne in 

 winter and spring. 



eminens, Baill. (P. paniciMtum, Benth. Ferdi- 

 ndnda eminens, Lag. Zaluzania Eminens, Hort. Cos- 

 mophyllum cacaliaefdlium, C. Koch). A tall shrub, 9-15 

 ft. high, slightly branched: Ivs. opposite, suborbicular 

 or broad-ovate, base short- or long-cuneate, slightly 

 5-7-lobed or subentire, rather scabrous above, cinerpus 

 or subtomentose pubescent beneath: ray-fls. white, 

 disk-fls. yellow. Mex., Guatemala. R.H. 1862, p. 110. 

 B.M. 8502. 



andinum, Andr6. Lvs. large, coarsely lobed: fl.- 

 heads in loose corymbs; ray-fls. white, disk-fls. yellow. 

 Colombia. R.H. 1892, p. 414. Said to be a useful plant 

 for subtropical bedding. jr. TRACY HUBBARD. 



PODALtRIA (named for Podalyrius, the son of 

 ^sculapius). Leguminosse. Shrubs, with alternate sim- 

 ple Ivs. which have subulate often deciduous. stipules: 

 infl. axillary, 1-2-, rarely 3-4-fld.; calyx broad-cam- 

 panulate, toothed or subequally lobed; petals subequal 

 in length, standard suborbiculate, emarginate, slightly 

 longer than the wings, with a short recurved claw, 

 wings obovate, oblique, keel shorter than the wings, 

 broad-obovate, slightly incurved; stamens free or very 

 shortly connate at base; ovary sessile, villpus, many- 

 seeded: fr. an ovoid or oblong turgid pod with leathery 

 valves. About 20 species, all of them S. African. P. 

 sericea, R. Br. AFRICAN SATIN-BUSH. Erect or pro- 

 cumbent, 4-6 ft. high, the whole plant with a satiny or 

 silvery luster, sometimes fulvous: branches silky: Ivs. 

 obovate or cuneate-oblong, acute at base, silky on both 

 surfaces: fls. pale-purple, solitary on trie peduncles; 

 calyx silky, lobes subulate acute, as long as the carina: 

 fr. a silky pod. Cape Colony. Intro, into S. Calif, 

 and also cult, abroad. The following species are men- 

 tioned as having been cult.: P. argentea, Salisb., P. 

 buxifolia, Willd., and P. calyptrata, Willd. 



PODANDRIA (Greek, foot and man or anther, prob- 

 ably referring to long-stipitate anthers). Orchidaceae. 

 Terrestrial herb with radical petioled Ivs. and large-fld. 

 racemes: sepals free, lateral narrower than the dorsal, 

 reflexed; petals simple, filiform-setaceous, erect, longer 

 than the dorsal sepal and free from it; lip continuous 

 with the column, shortly adnate to it, produced at the 

 base into a long cylindrical spur; limb pendulous, 3- 



Eartite with narrow lobes, column with a short broad 

 ase, footless; anther long-stipitate, pollinia granular 

 with very long slender caudicles; stigmas sessile, nearly 

 confluent, situated within the side lobes of the rostellum 

 and at their base, rostellum trilobed. The only species 

 is from W. Afr. The genus resembles Habenaria, in 

 which it has been included, in habit but is remarkable 

 for its enormously elongated anther and long narrow 

 segms. P. macrdndra, Rolfe (Habenaria macrdndra, 

 Lindl.). Plant %-!% ft. high, apparently evergreen: 

 Ivs. elliptic-oblong, 2-5 in. long: racemes 2-9-fld.; fls. 



large, white with a green tint on the sepals. G.C. III. 

 54 : 182. Intro, abroad and cult, by some orchid fanciers. 



PODOCARPUS (Greek, pous, podos, foot, and karpos, 

 fruit; alluding to the conspicuous fleshy footstalks of 

 most species). Including Nageia, Prumndpitys and 

 Stachycdrpus. Taxaceae. Ornamental woody plants 

 grown for their evergreen foliage. 



Resinous evergreen trees, rarely shrubs: Ivs. alternate, 

 sometimes opposite or 2-ranked, sessile or short-stalked, 

 linear to elliptic, entire: fls. monoecious or dioecious, 

 axillary or sub terminal, solitary or in spikes; the stam- 

 inate catkin-like, consisting of spirally disposed, 2- 

 celled anthers; the pistillate consisting of a scale inclos- 

 ing 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-Prum- 

 nopitys (Stachy carpus). 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 foot- 

 stalks 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 some- 

 times 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.
