rOLYANDRIA. MONOGYNIA. 5 



lines long-. Calls and leaves covered with an equal quan* 

 tily of pubescence, segments, after the manner of the ge* 

 nus oblique and convolute, tlie 2 smaller laciniae scarcely 

 visible in the fruiting calix, sufficiently distinct in the un- 

 expanded flowers. Capsule cylindric-oblong, externally 

 pubescent, central suture of the valves obsolete. 



2. *moiitanti. Adult plants partly smooth, and ces- 

 jiitosc; leaves longer, filiform, and subulate, subimbri« 

 cate; peduncles terminal, solitary; calix campanulate, la- 

 nuginous, segments acuminate, smaller ones lunger and 

 subulate; capsule villous, mostly 3-seeded, valves ovate, 

 partly septiferous. Hab. On the highest summits of 

 the mountains of North Carolina, forming extensive ces- 

 pitose patches; abundant on the romantic summit of the 

 Table- Uock, a singularly elevated and isolated portion of 

 the Catawba ridge, in company with Rhodode7idron Cata-w- 

 f'iense, ike. A very distinct species which I have careful- 

 ly compared with the preceding, r. t'. Obs. Stem 3 to 

 5 inches high, decumbeiU. Leaves about a line longer 

 than those of the preceding species, and to the naked eye 

 appearing almost smooth. Peduncles terminal, in fruit 

 about an inch long. Flower more than twice the size of 

 the preceding, with a lanuginous and campanulate calix, 

 having its smaller segments conspicuously exterted and 

 distinct. Stamina 25 to 30. Capsule 3 times the size of 

 the preceding, and furnished with distinct central septi- 

 form sutures. Seeds granulated, partly angular. — This 

 species approaches to Helianthemum, but still possesses 

 closely the habit of the preceding. 



3. *tomsntcsa. Cespitose, and canescently tomentose^ 

 leaves minute, closely imbricated, ovate acute, shorter 

 than the intervals of the stem; flowers aggregated, subses- 

 sile; calix subcylindric, segments obtuse; capsule 1-seed- 

 ed, valves ovate, smooth. Hab. On the drift-sands of 

 the ocean. New Jersey, Delaware, Maryland, &,c. A. 

 very distinct species. Obs. Stems intricate and densely 

 cespitose so as to arrest the motion of the sand in which 

 they grow; the whole plant silvery grey and tomentose, 

 young stems white with a dense tomentum. Leaves 

 scarcely a line long and connectively imbricated so 

 that the points are scarcely visible in profile; flowers 

 sessile, conglonnerated, brilliant yellow, and much more 

 elegant than those of H. ericoides. Calix silky, the smal- 

 ler segments obsolete. Stamina from 14 to 18. Capsule 

 S sided, smooth and polished, 1-seeded; valves furnished, 

 with distinctmedial sutures- Seed obsoletely granular,
