Spec. Char., §c, Pubescent, Stems suffruti- 
“ eose, erect.. Branches elongated. Leaves 
filiform, awl-shaped, rather imbricated, Pe- 
duncles solitary, rising laterally from the leafy 
bud. Calyx cylindrical, obtuse. Capsule 
pubescent, always l-seeded. Valves oblong. 
(Don’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.
