HALESIA 



HALIMODENDRON 



1429 



Deciduous and more or less stellate-pubescent: Ivs. 

 short-petioled, without stipules, involute in bud, 

 denticulate: fls. in axillary clusters or short racemes on 

 branchlets of the previous year; calyx-tube obconical, 

 slightly 4-ribbed, with 4 minute teeth; corolla cam- 

 panulate, 4-lobed or nearly 4-parted, white; stamens 



1783. Halesia Carolina var. Meehanii. ( X J^) 



8-16; style slender; ovary inferior, 2-4-celled, with 4 

 ovules in each cell: fr. an oblong, dry drupe with 2j-4 

 longitudinal wings; stone 1-3-seeded. Three species 

 in N. Amer. 



The snowdrop -trees are large shrubs or trees with 

 rather large bright green generally oblong and short- 

 stalked leaves and white slender-stalked drooping 

 bell-shaped flowers appearing before or with the 

 leaves and followed by winged light brown fruits. 

 Halesia Carolina is hardy as far north as Massachusetts 

 and is very handsome in spring when covered with its 

 white flowers. Halesia diptera is hardy as far north as 

 Philadelphia and is usually a smaller plant, but has 

 larger flowers and leaves. They thrive in almost any 

 good soil, but prefer a rich well-drained soil and a 

 sheltered position; they are easily transplanted. Prop- 

 agation is by layers or root - cuttings in spring or 

 autumn; also by greenwood cuttings taken from 

 forced plants. Seed should be sown at once or stratified; 

 if allowed to become dry, it does not germinate until 

 the second or sometimes the third year. 



Carolina, Linn. (H. tetrdptera, Ellis. Mohrodendron 

 carolinum, Brit.). Fig. 1782. Large shrub or small 

 tree, usually not higher than 40 ft., with spreading 

 branches and often irregular in habit: Ivs. ovate or 

 elliptic to ovate-oblong, acute or acuminate, cuneate 

 or rounded at the base, finely serrate, glabrous above, 

 stellate-pubescent below, 2-4 in. long: fls. in clusters 

 of 2-4; corolla 4-lobed, l A-%vb. long; stamens 10-16; 

 ovary 4-celled: fr. 4-winged, 1-1 1 A in. long. April, 

 May. W. Va. to Fla., west to 111. and E. Texas. B.M.

55:823. Var. dialypetala, Schneid. Corolla divided 

 nearly to the base. Var. monticola, Rehd. Pyramidal 

 tree to 90 ft.: Ivs. larger, generally oblong-obovate, 

 glabrescent or nearly glabrous below, more sharply 

 serrate: pedicels and calyx glabrous; corolla large: fr. 

 1^-2 in. long, obcordate at the apex, wings broad. 

 N. C. to Ala., in the mountains. Apparently hardier 

 than the type. Var. Meehanii, Perkins (H. Meehanii, 

 Meehan). Fig. 1783. Bushy upright shrub or small 

 tree: Ivs. thicker, smaller, more rugose, darker green, 

 more distinctly serrate, pubescent below: fls. smaller, 

 cup-shaped, shorter pedicelled. A very peculiar form of 

 garden origin; very unlike the species and less orna- 

 mental; suggests a hybrid of some kind. G.F. 5:535 

 (adapted in Fig. 1783). 



diptera, Ellis (Mohrodendron dipterum, Brit.). Shrub 

 or small tree, to 30 ft.: Ivs. ovate to obovate, rarely 

 oblong, remotely serrate, soft-pubescent beneath, 3-5 

 in. long: fls. 2-4, in short racemes; corolla deeply lobed 

 nearly to the base, puberulous outside; stamens usually 

 8; ovary usually 2-celled: fr. oblong with 2 broad wings 

 and often with 2 or sometimes 3 obsolete supplementary 

 ones, lJ'2-2 in. long. April. S. C. and Tenn. to Fla. 

 and Texas. S.S. 6:259.

 corolla \i- l /^n. long: fr. 2-winged. Ga. to Fla. 



ALFRED REHDER. 



HALIMODENDRON (Greek, maritime tree; refer- 

 ring to its habitat in saline soils). Legumindsse. Orna- 

 mental shrub grown for its handsome profusely pro- 

 duced flowers. 



Deciduous: Ivs. slender-stalked, with 1 or 2 pairs of 

 Ifts. and with the persistent petiole becoming usually 

 spinescent: fls. in lateral slender-stalked, 2-3-fld. 

 racemes; calyx cup-shaped with 5 short teeth; corolla 

 papilionaceous; petals of nearly equal length; standard 

 orbicular with the sides reflexed; keel obtuse, curved; 

 stamens diadelphous; ovary 

 stipitate with many ovules, 

 style filiform, curved: pod 

 stipitate, ellipsoid or obovoid, 

 inflated, tardily dehiscent, 

 with few kidney-shaped glossy 

 brown seeds. One species 

 in the salt steppes of Cent. 

 Asia from Transcaucasia to 

 the Altai. 



This is a wide -spreading 

 shrub with slender branches 

 and small bluish green foliage, 

 covered in early summer with 

 numerous pale violet or rosy 

 purple flowers. The small pale 

 foliage and the slender-stalked 

 drooping flowers combined 

 with the spreading habit give 

 to the plant a gracef ulness and 

 airiness of its own and make 

 it a very desirable ornamental 

 shrub. It is perfectly hardy 

 North, resists drought and 

 heat well and thrives in sandy 

 as also in saline and alkaline 

 soils. Propagation is by seeds 

 and by layers which root 

 slowly; it also may be grafted 

 on laburnum or caragana.
