 Anthers small, opening lengthwise. Style straight, simple, equalling the sta- 

 mens in length. Stigma simple. Capsule 1-cellecl, 3-valved, 1 — 3-seeded,

Spec. Char., S^c, Pubescent. Stems suffruti- 

 cose, erect. Branches elongated. Leaves 

 filiform, awl-shaped, rather imbricated. Pe- 

 duncles solitary, rising laterally from the leafy 

 bud. Calyx cylindrical, obtuse. Capsule 

 pubescent, always 1-seeded. Valves oblong. 

 {Bon's Mill., i. p. 315.) A heath-like shrub, 

 native of New Jersey and Virginia, in pine 

 woods, and introduced into England in 1805. 

 It is a short, densely branched, sufFruticose 

 plant, rather scarce in British collections. 

 Its flowers are yellow, small, solitary, and 

 produced from May to July. The plant is 

 rather more difficult to cultivate than those 

 of the other genera of this order; but it 

 thrives very well in sandy peat ; its native 

 habitat being similar to that of the common 

 heath in England.

Spec. Char., 8;c. Equally pubescent. Stem erect, much branched. Leaves about 2 lines long, iili- 

 form, 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 two smaller ones hardly visible when in fruit, but sufficiently distinct in the unexpanded 

 flowers. Capsules cylindrical, oblong, externally pubescent, always 1-seeded. Valves oblong; 

 the central suture obsolete. {Don's Mill., i. p. 315.) An evergreen undershrub, closely resembling 

 H. eric5ides, and perhaps only a variety of it.

■ Leaves minute, densely imbricated, ovate, acute. Flowers aggregate, almost 

 sessile. Calyxes rather cylindrical, with obtuse partitions. Capsules 1- 

 seeded. Valves ovate, smooth. {Don's Mill., I p. 316.) Found in New 

 Jersey, Delaware, Maryland, &c., in the sea sand. It was first dis-

 Mr. James M'Nab, in " An Account of some of the rarer Plants, observed 

 during an Excursion in the United States and the Canadas in 1834," pub- 

 lished in the Edinburgh Neiu Philosophical Journal, No. 37., July, 1835, says
