manifestly reticulate-veined beneath. Heads middle-sized or rather large, 

 crowded on the short erect racemes, and disposed in a dense spike or thyrsus 

 3-5 inches in length, about 25-flowered. Rays short and inconspicuous. 



16. <S. Californica (Nutt.) : villous and cinereous : leaves nearly all equal 

 and somewhat crowded, oblong-lanceolate, acute at each end, near the apex 

 sometimes very slightly serrulate; panicle elongated, nearly e(iual; scales 

 of the involucre lanceolate, acute, somewhat pubescent ; rays about 9 ; 

 achenia pubescent. Nutt. ! in trans. Amer. phil. soc. (n. scr.) 7. j). 238. S.

St. Barbara, California, Nuttall. 0. Monterey, California, Capt. Beech- 

 ey ! — "Two or 3 feet high. Discal flowers about 9, as well as the rays. 

 AlUed to the preceding [S. nana] ; but softly villous and acute-leaved : the 

 stem-leaves are also nearly as large as the radical ones, about an inch or an 

 inch and a half long, by less than half an inch wide." Nutt. — In the only 

 specimen of var. /?., the lower part of the stem is wanting: the leaves are 

 much hke those of S. ovalifolia; the lower 1-2 inches long, considerably at- 

 tenuate at the base, the upper successively smaller, some of them obscurely 

 serrate towards the apex. The heads are not much larger than in S. nemo- 

 ralis, 14-16-flowered, crowded ; the rays small, about 7. Scales of the invo- 

 lucre lanceolate, acutish, slightly pubescent. The terminal portion of the 

 panicle or compound raceme appears to have been somewhat curved and 

 unilateral. 



17. S. petiolaris {kit.) : stem simple and virgate, often branching above, 

 leafy, covered with a close pubescence, nearly tomentose at the summit ; 

 leaves oval or elliptical, mucronulate, veiny, somewhat scabrous above and 

 puberulent-tomentose beneath (at least the midrib and veins), scabrous-cilio- 

 late; the upper mostly entire, abruptly and slightly petioled ; the lower often 

 serrate, narrowed at the base : heads "(rather large) in a single virgate ra- 

 ceme or several paniculate racemes ; scales of the pubescent involucre lan- 

 ceolate ; the exterior loose or spreading, somewhat herbaceous; rays about 

 10, elongated; achenia at length glabrous. — Ait.! Keto. [eel. 1) 3. p. 216 ;

 herbaceous, somewhat squarrose. — S. squarrosa, Nutt. ! in jour. acad. Philad.

Pine barrens and sandy, usually dry soil, North Carolina ! to Georgia ! 

 Florida ! and Western Louisiana ! Aug.-Sept. — Stem 1-2, rarely 3 feet 

 high, clothed with a fine and short somewhat hoary pubescence, which at 

 the summit and on the peduncles, &c. is tomentose. Leaves pale, almost 

 glabrous or slightly scabrous above, prominently feather-veined beneath, and 

 often somewhat reticulated, either obtuse or acute, 1-2 inches long, gradually 

 diminishing in size upwards; the lower more or less narrowed at the base, 

 but very slightly petioled, usually serrate with small scattered teeth ; the 

 upper rounded at the base, sUghtly petioled, it may be, but appearing sessile. 

 Raceme usually virgate, terminating the stem or "branches ; or often several 

 disposed in a panicle, rarely nearly simple ; the heads usually 2-5 on each 

 short peduncle, and on mostly slender bracteolate pedicels, pretty large, 20- 

 25-flowered. Rays bright yellow. Achenia minutely pubescent when 

 young, glabrous when mature. Inner scales of the involucre witli somewhat 

 greenish tij)*, appressed ; the exterior short and loose, gradually i)assing 

 into the subulate bracts of the pedicels : in var. ii. these bracts are more
