13. S. puberula (Nutt.) : very minutely puberulent; stem simple; cau- 

 line leaves lanceolate, acute, tapering to the base, sessile, mostly entire ; the 

 lower oblanceolate and somewhat serrate ; the lowest and radical oblong- 

 spatulate, serrate towards the apex, petioled ; heads (middle-sized) in nume- 

 rous compact erect-spreading racemes (often compound), forming an elonga- 

 ted or sometimes thyrsiform panicle; scales of the involucre linear-subulate, 

 appressed; ravs about 10, elongated ; achenia nearly glabrous. — Nutt..' gen.

Sandy woods &c. mostly in damp soil, Maine {Mr. Oakes !) and Mas- 

 sachusetts ! New Jersey ! &c. to Georgia ! Aug.-Oct. — Stem 2-4 feet high, 

 strict, often purplish. Leaves thin, soft to the touch from the minute pubes- 

 cence, which is scarcely visible to the naked eye, somewhat veiny; the 

 radical ones 3-6 inches long, including the slender winged petioles, obtuse ; 

 the lower cauline 2-3 inches long and 6-8 lines wide, gradually diminishing _ 

 upwards. Racemes very numerous, either short and disposed in a long and 

 dense virgate compound raceme, or narrow panicle ; or with the lower ra- 

 cemes elongated, and either simple or compound, forming a more expanded 

 panicle. Heads about 28-flowered : rays golden yellow. Achenia very 

 minutely pubescent under a lens, glabrous or nearly so when mature. 



14. S. ronferdflora (DC.) : herbaceous, glabrous, viscous ; stem simple, 

 leafy to the thyrsus ; leaves oval-lanceolate or oblong-lanceolate, serrate at 

 the apex, entire below, tapering (particularly of the lower ones) into long pe- 

 tioles ; heads 8-14-flowered, very much crowded in a spiciform thyrsus; 

 scales of the involucre linear, erect ; rays few and small. — DC. ! proclr. 5.

Nootka and Mu [grave Sound, Hfenke ex DC. Plains of the Oregon and 

 Wahlamet, Nuttall ! — " About 2 feet high, with a brown stem, angular 

 above ; lower leaves 3 or 4 inches long, by about half an inch wide ; the 

 radical attenuated into long petioles. Upper part of the stem, bracts, and in- 

 volucrum indued with an orange varnish-like resin, of a strong, aromatic, and 

 rather unpleasant taste. Rays about 8-10 [we observe 5-8] : discal florets 

 5 or 6 : pappus of the rays a little shorter," Nutt. — Not having compared the 

 two, we are not certain that the S. glutinosa, Nutt. is the S. conferliflora, 

 DC. ; but we find no essential difference. In the former, the radical leaves 

 are lanceolate-spatulate, 3-4 inches long, sharply serrate near the apex, with 

 a long attenuate entire base, veiny and somewhat triplinerved : the cauline 

 2-3 inclies long, 3-4 lines wide, rather obscurely reticulate-veined, the lower 

 more attenuate at the base. Heads middle-sized, in short glomerate racemes 

 which are aggregated in a spiciform panicle. Exterior scales of the involu- 

 cre ovate or roundish, very short ; the middle ones ovate-oblong, the inner- 

 most linear-oblong. Rays small. Achenia minutely pubescent. 



15. <S. spiciforniis : glabrous or nearly so ; stem ascending, simple (some- 

 what glutinous?); leaves obovate-spalulate, finely serrate, tapering into a 

 narrow entire base, or the lower into long margined petioles, reticulate- 

 veined ; racemes short, crowded in a dense spike or thyrsus; scales of the 

 involucre oblong, very obtuse, appressed, nearly glabrous ; rays about 7, 

 very small ; achenia silky-pubescent. — S. petiolaris, (Less, in Linntea, I. c?)

Monterey, California, Capi. Brcchcy ! (v. sp. in kerb. Hook.) — Stem 

 stout, 8-12 inches high; the base decumbent and apparently somewhat per- 

 sistent, densely clothed with spatulate leaves, which taper into slender petioles : 

 above with more scattered and less ]5etioled leaves ; those near the summit 

 small and sessile. The leaves are all glabrous (jr nearly so, usually serrate 

 with close and fine acute teeth, except the narrowed base, mostly obtuse, and
