FTEROCARTA (from ptewn, a wing, and caryon, a 

 nut ; referring- to the winged fruit). Okd. Jw/landece. 

 A small genus (three or four species) of hardy, deciduous 

 trees, natives of temperate Asia. Flowers unisexual, 

 moncEcious, in long, pendulous spikes. Fruit drupaceous, 

 dry, angled, having two wings as the ovary, much 

 tapered at the tip, not opening. Leaves ample ; leaflets 

 often numerous, narrow. The species are seldom seen 

 in gardens. They thrive best when planted near water ; 

 in such spots, P. fraxinifolia makes one of the most 

 ornamental of deciduous trees. All the species are easily 

 raised from seed, imported or ripened in this country.

FTEBiODISCUS (from pteron, a wing, and discus, 

 a disk ; referring to the broad wings of the disk of the 

 fruit). Okd. Pedalinecg. A genus consisting of only three 

 species of greenhouse, herbaceous plants, with tuberous 

 roots, or with a thick, succulent stem, which becomes 

 tall under cultivation ; two are natives of South Africa, 

 and the third is Angolan. Flowers purple or lurid- 

 yellow, solitary in the axils, very shortly stalked or 

 almost sessile ; calyx small, five-parted ; corolla tube 

 gibbous at base, swollen upwards ; limb somewhat bi- 

 labiate, with five broadly rotundate, spreading lobes. 

 Leaves opposite or alternate, narrow, toothed or cut, 

 rather thick, oanescent. The only species worth growing 

 is P. speciosus. This is a handsome plant, and thrives 

 best under the influence of a full exposure to sunlight. 

 It requires a compost of sandy loam and leaf mould. 

 Propagated by seeds, sown in spring and autumn ; and 

 by dividing the plant, in spring. P. luridus requires 

 similar treatment. 



P. luridus (lurid). /. dull yellow, tubular. July. I. linear- 

 oblong, deeply lobed, almost pinnatifid. h. IJft. South Africa, 

 1868. A gouty-stemmed plant, of little horticultural value. 

 (B. Jl. 5784.) 



P. speciosus (showy).* Jl. of a beautiful lilac or reddish colour, 

 axillary, siditary, large, with a funnel-shaped tube, and a spread- 

 ing, flve-lobed limb. May. I. opposite, sinuate, dentate. Stem 

 branching into several erect, thick branches. Roots large, 

 globose, tuberous, the upper part elevated above the eai-th. 

 h. 2ft. South Africa, 1818. (B. M. 4117.) 



FTEBOLOBIUM (from pteron, a wing, and loboe, 

 a pod ; the pods are i>roduced into a wing at the ex- 

 tremity). Syns. Quarfinia, Reichardia. Ord. Legumi- 

 nosce. A genus comprising four species of taU, climbing, 

 stove shrubs, armed with recurved prickles ; they are 

 natives of tropical Asia, Africa, and Australia. Flowers 

 white (or yellowish ?), small, racemose ; racemes at the 

 tips of the branches, loosely paniculate ; calyx segments 

 five, imbricated ; petals five, spreading, imbricated. 

 Pods sessile, compressed, samaroid, indehiscent, the apex 

 produced into an oblique, oblong or falcate wing. 

 Leaves bipinnate ; leaflets small, numerous ; stipules small 

 or inconspicuous ; bracts very caducous. P. indie um — 

 the only species introduced — requires culture similar to 

 Csesalpinia (which see). 



P, indicum (Indian). /. yellowish, axillary only from the extreme 

 leaves, which gives them an appearance of a large, terminal, leafy 

 panicle. I. alternate, abruptly bipinnate. Sin. to 6in. long, 3in. 

 broad : pinna* opposite, four to eight pairs, oval, entire, smooth, 

 sin. long, Jiu. broad ; petioles armed with three prickles. East 

 Indies. Sv.N. Cixsalpiiiia laceram.

 Syn. Velaija. Ord. Sterculiacece. A genus comprising 

 about fourteen species of stove, scaly or stellate-tomeu- 

 tose trees or shrubs, natives of tropical Asia. Flowers 

 often elongated, sometimes several inches long ; calyx 

 tubular, five-cut or parted, deciduous ; petals five, ob- 

 ovate, oblong, or linear, deciduous ; peduncles axillary, 

 short, one or few-flowered. Leaves coriaceous, often 

 oblique, entire or the uppermost ones angialarly toothed, 

 penninerved, and three to seven-nerved at the base. 

 The species best known to cultivation are those described 

 below. They thrive in a compost of sandy, fibry loam 

 and lumpy peat ; and perfect drainage is most essential. 

 Propagated by cuttings of half-ripened side shoots, cut 

 close to the stem, and inserted in sand, in bottom heat. 



P, acerifolium (Maple-leaved). Jl. white ; pedicels shorter than 

 the jietioles. July to September. I. broad, peltately-cordate, ob- 

 tuse, with a short acumen, toothed, tomentose beneath, upper 

 surface white, clothed with stellate hairs. East Indies, 1790. A 

 large tree. This species thrives well under greenhouse treatment.

 twin or tern at the tops of the branches ; pedicels hardly the 

 length of the petioles, crowded. I. oblong, acuminate, obli<iuely 

 cordate at the base, coarsely toothed at the apex, tomentose
