monotypic genus. The species is a very pretty, silky, 

 hardy deciduous shrub, forming a handsome plant when 

 grafted upon the Laburnum as a standard. It thrives 

 in a sandy soil, and may be increased freely by seeds, 

 by cuttings, or by layers. 

 H. argenteum (silvery).* fl. purplish, rather large, umbellate, 



axillary, or fascicled on the old nodes. May to July. I. hoary,

HALLERIA (named after Albert Haller, 1708-1777, 

 author of " Stirpes Helveticte," and other botanical 

 works). OED. Scrophularinece. A genus containing about 

 five species of ornamental greenhouse evergreen glabrous 

 shrubs, of which one is from Abyssinia, another from 

 Madagascar, and the rest from the Cape of Good Hope. 

 Flowers scarlet ; cymes terminal, few-flowered ; calyx cup- 

 like, bell-shaped, with three to five broad, short lobes ; 

 corolla tubular, widening upwards, with an oblique, shortly 

 five-lobed limb. Leaves ovate or oblong. Hallerias thrive 

 in light, rich soil. Propagated by cuttings, which will 

 root freely under a glass. Plenty of water is needed 

 during summer, and a well-ventilated spot is at all times 

 necessary. The species described below is the one usually 

 seen in cultivation. 



H. lucida (shining). African Honeysuckle. /. reddish, large, 

 drooping ; corolla bilabiate. June. I. ovate, acuminate, ser- 

 rated. h. 4ft to 6ft. Cape of Good Hope, 1752. (B. M. 1744.) 



HALLIA (named in honour of Bergen Martin Hall, a 

 pupil of Linnaeus). OED. Leguminosce. A genus contain- 

 ing six species of erect or decumbent greenhouse peren- 

 nial herbs or sub-shrubs, all natives of South Africa. 

 Flowers purple, small, axillary, solitary. Leaves alter-

 spike, rarely pedicelled, sometimes panicled. Leaves 

 usually opposite or whorled, simple, entire or toothed. 

 the submerged ones usually pectinate, rarely entire; 

 stipules none, or (in Gunnera) adnate to the petiole. The 

 species are sparingly dispersed throughout the world, 

 and may be found in damp places, ditches, and small 

 streams, sometimes submerged. There are nine genera 

 and eighty species. Well-known examples are: Gunnera 

 and Hippuris.

HAMAMELIDE2E. A small order of shrubs or 

 small or large trees, inhabiting temperate and sub-tro- 

 pical Asia, South Africa, and North America. Calyx 

 four-partite, more or less adnate to the ovary ; limb trun- 

 cate or five-lobed; lobes valvate or imbricate. Leaves

 moist sandy soil, and may be propagated by layers. 

 During autumn and winter, the plant is profusely covered
