Cult. The hardy shrubby kinds of this genus are amongst 

 the most beautiful little shrubs for ornamenting rock-work. The 

 frame and green-house kinds should be planted in pots in a mix- 

 ture of sand, loam, and peat, so that they may be protected during 

 winter by a frame ; the smaller kinds of these may be planted 

 out on rock-work during the summer months. Ripened cuttings 

 will strike root freely, if planted under a common hand-glass in 

 a sheltered situation, in August or September ; or they may be 

 raised by seeds, which ripen in abundance. The perennial

and biennial herbaceous kinds should be grown in pots, (so 

 that they may be protected by a frame during winter), in a 

 mixture of sand, loam, and peat ; they are easily increased by 

 seeds. The annual kinds are all beautiful plants, and the seed 

 requires to be sown in the open border : they prefer a light rich 

 soil. All the species of Helidnthemwn deserve to be cultivated in 

 every collection on account of the elegance and various hues of 

 their blossoms. 



III. HUDSONIA (in honour of William Hudson, a London 

 apothecary, and author of Flora Anglica, 1762 and 1778, 8vo.) 

 Lin. mant. 11. Nutt. gen. amer. 2. p. 4. D. C. prod. 1. p. 284. 



LIN. SYST. Polydndria, Monogynia. Petals 5 (f. 61. a. &.). 

 Stamens 15-30 ; filaments filiform ; anthers small, longitudinally 

 dehiscent. Style straight, simple (f. 61. e.}, equalling the sta- 

 mens in length. Stigma simple. Capsule 1 -celled, 3-valved, 

 1-3-seeded, oblong or obovate, coriaceous, smooth or pubescent. 

 Seeds granulated. Embryo immersed in a horny albumen. 

 Small tufted heath-like sub-shrubs. Leaves alternate, small, 

 awl-shaped or needle-shaped, imbricated, without stipulas. 

 Flowers yellow, almost sessile or on short peduncles ; peduncles 

 1 -flowered, terminal, or lateral, solitary, or aggregate. 



1 H. ERICOI DES (Lin. mant. 74.) 

 pubescent ; stems suffruticose, 

 erect ; branches elongated ; leaves 

 filiform, awl-shaped, rather imbri- 

 cated ; peduncles solitary, rising 

 laterally from the leafy bud ; calyx 

 cylindrical, obtuse ; capsules pu- 

 bescent, always 1 -seeded; valves 

 oblong. Tj . F. Native of New 

 Jersey and Virginia in pine woods. 

 Willd. hort. berl. t. 15. Sweet, 

 cist. t. 36. Leaves permanent. 

 Stamens about 15. Peduncles 5 or 

 8 lines long. According to Nuttal, 

 this plant, which is a native of New 

 Jersey, has aggregate instead of 

 solitary peduncles ; therefore his 

 plant may be a distinct species. 

 Flowers yellow (f. 61.). 



Heath-like Hudsonia. Fl. May, July. Clt. 1805. Shrub 1 ft. 



2 H. NUTTA'LLII (Sweet, cist. p. 19.) equally pubescent; 

 stem erect, much branched ; leaves about 2-lines long, filiform, 

 rather imbricate, but distinct from the stem ; pedicels lateral, 

 crowded, when in fruit from 5 to 8 lines long ; calyx cylindrical, 

 obtuse, pubescent, with the segments oblique and convolute, 

 the 2 smaller ones hardly visible when in fruit, but suffi- 

 ciently distinct in the unexpanded flowers ; capsules cylin- 

 drical-oblong, externally pubescent, always 1 -seeded ; valves 

 oblong, the central suture obsolete. J? . F. Abundant over 

 the barren sandy woods of New Jersey, Delaware, Mary- 

 land, and Virginia (Nutt.) H. ericoides, Nutt. gen. amer. 2. p. 

 4. Whether this plant is identical with the H. ericoides of Lin. 

 it is impossible to say.

 Carolina on the summits of mountains. Stamens 25-30. Seeds
