HALESIA 



are rather short-lived, except in var. Meehani. Prop, 

 most commonly by layers, also by root-cuttings in spring 

 and autumn; and by seeds, which should be kept con- 

 stantly moist, as they rarely germinate until the second 

 year if allowed to dry. H. dipterd is hardy as far north 

 as Philadelphia, but of doubtful hardiness farther north, 

 though it may become acclimatized. Thrives best in a 

 cool, deep loam. Prop, by seeds, which should never be 

 allowed to dry, and by grafting on H. tetraptera. 



tetraptera, Linn. Fig. 1016. A small tree or shrub 

 8-10 , whose fls. resemble those of a snowdrop. Lvs. 

 ovate or ovate-oblong, finely serrate, dark green and 

 glabrous above, pale green and stellate-pubescent be- 

 low, 2-4 in. long: fls. in lateral clusters of 2-4 ; co- 

 rolla 4-lobed, 1 in. long: ovary 4-celled: drupe ellip- 

 soidal, longitudinally 4-winged, 1-1K in. long. Va. S. 

 and W. B.M. 910. Mn. 5, p. 194. S.S. 6:257. Gng.

 Meehani, Sargent (ff. Meehani, Hort.). Fig. 1017. Habit 

 wholly unlike that of the type, round, bushy and more 

 upright, from a distance looking like an apple tree, 12 

 ft. high. Has thicker, rugose, dark green Ivs., on young 

 plants glandular serrate, and smaller, more numerous 

 fls with short calyx-tubes and cup-shaped corollas, with- 

 out the narrow base. Seems barren, but is not a hy- 

 brid. Growth smaller. G.F. 5:535. Gng. 2:247. 



dfptera, Ellis. A small tree or shrub from the South 

 not easily distinguished from If. tetrapte'W. The Ivs. 

 are larger, ovate, green on both sides, coarsely serrate 

 and downy: fls. white, on long pedicels, in racemes of 

 24, more showy than those of H. tetraptera ; petals 4, 

 nearly distinct, 1 in. long : ovary 3-celled : drupe with 

 2 large opposite wings and 2 obsolete. Early June. 

 S.S. 6:259. Plant not so large as of H. tetraptera: 

 Ivs. larger and fls. more showy. 



H. cnrinribbsa, Nich.=Pterostyrax corymbosa. H. hispida, 

 Mast.=Pterostyrax hispida. H. parviflora, Miehx. Much like 

 H. tetraptera, but shrubby, with, smaller fls. and 2-winged fr,

HALIMOD^NDEON (Greek, salt tree ; referring to 

 the maritime habit of the plant). Legumlnbsce. A 

 genus whose sole representative is a hardy deciduous 

 shrub 4-10 ft. high, growing in the dry, barren salt- 

 fields of Siberia. It is characterized by the small, equally 

 pinnate Ivs. ending in sharp, stinging spines, and com- 

 posed of 1-2 pairs of clean Ifts., and by the rather large 

 rose-purplish fls., in 2-3-fld. lateral fascicles from the 

 old nodes at the base of the summer shoots, appearing 

 from May-July. The branches are whitish and prickly, 

 with small petiolar spines. In cultivation the shrub 

 ..is very hardy, enduring both drought and cold, and, 

 while it thrives in sandy soils, it succeeds, also, in 

 saline or alkaline. The rosy fls. and the airiness of 

 the fine Ivs. make it very ornamental. It is propagated 

 by seeds, layers and cuttings, or may be grafted upon 

 the common Laburnum, upon Caragana arbrrescens, 

 or Colutea arborescens. 



argenteum, Fisch. SALT TREE. Lvs compound; Ifts. 

 spatulate or long-oval, mucronate, blue-green, more or 

 less pubescent: tts. irregular, papilionaceous; calyx 

 cup-shaped, with 5 short teeth; petals of nearly equal 

 length ; standard orbicular, with the sides turned back- 

 ward; keel obtuse, straight; stamens diadelphous, un- 

 equal: ovary stipitate, few-ovuled: style filiform: pod 

 inflated, ovoid, hard, depressed in the seed-bearing por- 

 tion, 6-7 in. long; seeds oval, sub-compressed. B.M. 1016.

HALLfiEIA (Albrecht von Haller, 1708-1777, Swiss 

 physician and naturalist, and professor at Gottingen). 

 Scropitnlariacece. About 6 species of shrubs from 

 Africa and Madagascar, one of which is cult, indoors 

 abroad and outdoors in S. Calif. H. lucida, Linn., grows 

 4-6 ft. high, has opposite, ovate, acuminate, serrate Ivs., 

 and axillary clusters of about 6 reddish, tubular fls., each 

 about 1 in long. The fls. are bulged on one side, with 2 

 short teeth in one lip and 3 in the other, and sometimes 

 yellowish at the base. Stamens 4, didynamous, exserted. 

 B.M. 1744. Sometimes called African Honeysuckle.

HAMAMELIS 



HAMAMfiLIS (Greek, hama, together, and melon, 

 apple or fruit : fruits and flowers at the same time). 

 ffamameliddcece. WITCH HAZEL. Hardy ornamental 

 shrubs or small trees, with deciduous, alternate, short- 

 petioled Ivs., yellow fls. in axillary clusters, appearing 

 late in fall or early in spring, and with capsular fruits. 

 Valuable on account of their blooming at a time when 

 hardly any other shrub outdoors is in flower ; well 

 adapted for shrubberies ; of compact, bushy habit and 

 with handsome foliage, turning bright yellow, orange of 

 purple in fall. It thrives best in somewhat moist, peaty 

 and san ly soil. The Japanese species likes a more 

 sunny position than the American, and is less moisture- 

 loving. Prop, by seeds, which do not germinate until 

 the second year, or by layers; rarer kinds also by graft- 

 ing on seedlings of ff. Virginiana in spring "in the 

 greenhouse. Three closely allied species in eastern N. 

 Amer., China and Jap. Lvs. stipulate, crenate-den- 

 tate: fls. in short-peduncled, nodding, axillary, few-fld. 



1018. Witch Hazel, Hamamelis Virginiana. 

 Showing flowers and fruits. Natural size. 



clusters, perfect; calyx 4-parted; petals 4, linear, 

 crumpled ; stamens 4, very short : fr. a dehiscent, 

 woody, 2-celled capsule, with 2 shining black seeds. 

 The seeds are shot out with considerable force. Occa- 

 sionally writers spell the common name Wych Hazel, 

 but there seems to be little historical reason for it 

 Witch, as used in Witch Hazel and Witch Elm, is prpt 

 ably allied to weak, referring to a drooping or straggling 

 habit. 



Virginiana, Linn. Fig. 1018. Shrub or small tree, 

 attaining 25 ft. : Ivs. oblique and cordate at the base, 

 obovate, coarsely crenate, pubescent on the veins be- 

 neath, 4-6 in. long; petals bright yellow, %-% in. long ; 

 calyx dull brownish yellow inside : fr. surrounded by 

 the calyx to one-half. Sept., Oct. Canada to Fla., west 

 to Neb. and Tex. Em. 472. S.S. 5:198. B.M. G684.

Japdnica, Sieb. and Zucc. Shrub or small tree, to 30
