SYNGENESIA. SUrERFLUA. 157 



Iff Leaves lanceolate and ovate, lotver ones serrate. 



Flowers fastigiate or corymbose. 



36. • nudijloms. Stem simple and smooth; leaves ses- 

 sile, ovate-lanceolate, subacuminatc, and all sharply ser- 

 rate, upper surface scabrous; corymb simple, few-flower- 

 ed; peduncles pubescent, naked, mostly 1-flowered; calix 

 hemispherical, closely imbricated, shorter than the disk» 

 scales linear-oblonj^, and ciliate. Hab. In the swamps of 

 N. Jersey; rare. Detected by \V. Stuve, M. D. Stem 2 

 or 3 feet high. Leaves about 3 inches long, and an incli 

 wide, the lower ones acuminate, and cuneate at the base, 

 the uppermost oblong-ovate, acute, and not much smaller. 

 Peduncles 3 to 5, mostly 1-flowered, 3 or 4 inches long, 

 lateral ones longest. Flower large, pale violet-purple, 

 with many rays which are longer than the calix. Nearly 

 allied to the following. 37. Radnla. 



38. peregri7nis. o9. stiictns. Scarcely distinct apparent- 

 ly from the following. 40. surculosiis. Stem simple, lovr 

 and slender, minutely pubescent; lower leaves linear-lan- 

 ceolate, entire, or subserrate, above scabrous, tipper ones 

 linear, amplexicaule; corymb 3 to 5-flowered, somewhat 

 naked; calix imbricated, subsquarrose, scales ciliate, li- 

 near-oblong, inner ones obtuse; rays about 20. Hab. On 

 the margins of open bushy swamps and Savannahs, in Ten- 

 nessee, North Carolina and Virginia. Nearly allied to the 

 following, but smaller and slender. Stem 12 to 18 inches 

 high. Root stoloniferous and creeping. Radical leaves 

 spathulate, or oblong-lanceolate, sometimes near a span 

 long, with the sheath ciliated. Flowers rather large, of 

 a bright violet-purple; inner scales of the calix often co-^ 

 loured. The habit of this plant is very much like that of 

 a corymbose Liatris; the pappus is also scabrous, but the 

 seed smooth. It appears to be ^2. elegans of Willdenow. 

 41. spectabilis. Leaves oblong-lanceolate, partly sca- 

 brous, and subamplexicaule, lower ones serrate in the mid- 

 dle, branches corymbose, calix hemispherical, somewhat 

 glandularly pubescent, foliaceous and squarrose, leaflets 

 ciliate, cuneate-ovate, and partly acute. Hab. In New Jer- 

 sey, common. Corymb, 10 to 15-fiowered, the branches 

 2 or 3-flowered, subpilose; flowers blue and large. The 

 viscidly pubescent calix and peduncle, with the numer- 

 ous flowers, and the approximating equality of the leaves, 

 distinguish this species readily from the preceding; the 

 hemispherical calix and numerous rays (more than 20), 

 likewise separate it from the following. /3. *bellidifoUus. 

 Leaves oblong-obovate, serrate; corymb nearly simple, 

 or with the branchlets mostly 1-flowered. N.Jersey. Stem 

 never pilose as well as glandular above.
