.S'. gnaphaloides (Nutt. ! 1. c.) 



Near Monterey, California, iVMftaZZ /— Plant about 6 inches high. — Chaff, 

 includinij the minute achenia, at length deciduous from the slender spirally 

 punctate receptacle. — The fertile flowers have the same corolla as the pre- 

 ceding genera ; and what Mr. Nuttall describes as a few long chaffy hairs 

 produced at the apex of the receptacle, is the pappus of the sterile flowers. 



Subtribe 4. ly\)-LY.s.,Cass. — Heads mostly radiate and heterogamous, never 

 dioecious. P.eceptacle not chaffy. Anthers caudate at the base. — Leaves 

 alternate. Heads not glomerate. Ray-flowers of the same color as the disk.

Heads many-flowered ; tlie ray-flowers in a single series, pistillate, but 

 sometimes infertile, ligulate, or rarely somewhat tubular ; those of the disk 

 tubular, perfect. Involucre imbricate in several series. Receptacle flat or 

 somewhat convex, naked. Anthers bisetose at the base. Achenium terete 

 or 4-sided. Pappus a single series of capillary slightly scabrous bristles. — 

 Mostly perennial herbs (natives of Europe and Asia), with the cauline leaves 

 often clasping. Heads solitary or corymbose at the summit of the pedun- 

 cles. Flowers yellow. 



§ Exterior scales of the involucre broadly ovate, foliaceous ; the inner ohovate- 

 sjmtulate, obtuse : achenia 4-sided, glabrous ; rays ligulate, numerous, nar- 

 rowly linear. — Corvisartia, Merat, Cass. 



1. J. Helenium (Linn.) : leaves (large) velvety-tomentose beneath, denti- 

 culate; the radical ones ovale, tapering into a petiole; the cauline partly 

 clasping ; heads solitary at the summit of the stout somewhat corymbose 

 peduncles.— Lmra. .' sjjec. 2. p. 881 ,• Fl. Dan. t. 728 ; Lam. ill. t. 680 ;

Road-sides and about houses, introduced from Europe, and naturahzed in 

 many places. — The thick and branching perennial root is mucilaginous and 

 slightly bitter, and is employed as a popular remedy. — The old officinal 

 name is Emda Camyana, whence Elecampane. 



Subtribe 5. Ecliptes, Less. — Heads radiate, heterogamous, never dioe- 

 cious. Receptacle chaffy. Anthers not caudate at the base. Pappus none, 

 or awn-like. — Leaves opposite. (Plants with nearly the habit and structure 

 of Helianthese, except the style, which corresponds with Asteroides.)

Heads many-flowered; the ray-flowers ligulate, pistillate, in a single 

 series; those of the disk perfect and tubular. Involucre hemispherical, im- 

 bricated ; the exterior scales foliaceous. Receptacle flat, covered with lan- 

 ceolate rigid persistent chaffy scales, as long as, or sometimes shorter than 

 the flowers of the disk. Corolla of the ray short and broad ; of the disk 

 scarcely dilated at the throat, 5-toothed. Anthers blackish, tipped with an
