 filiform, awl-shaped, rather imbricated. Pe-

 (Don's Mill., i. p. 315.) A hcath-hke shrub, 

 native of New Jersey and Virginia, in pine 

 woods, and introduced into England in 1805. 

 It is a short, densely branched, sufFruticose 

 ])lant, 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., Sfc. Equally pubescent Stem erect, much branched. Leaves about 2 lines long, fill. 



"^ form rather imbricate, but distinct from the stem. Pe<iicels 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-secded. Valves oblong ; 



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



H. t-ricoldes, and perhaps only a variety of it.
