COMPOSITE. 417 



with whitish hairs : leaves narrowly linear, the uppermost involucrately 

 subtending the small subsessile heads (or some earlier heads slender- 

 peduncled): achenes narrowly oblong-obovate or somewhat fusiform, 

 manifestly obcompressed with the inner face slightly angled, tipped 

 with a short incurved beak. — In the mountains from the Yosemite region 

 northward. 



3. H. iniiiiiuus. Hemizoaia minima, Gray, 1. c. (1865) and Hemi- 

 zonelia ininiina, 1. c. (1874). Very dwarf, only about 1 in. high: lowest 

 leaves oval or oblong, the others linear, but scarcely more than ^4 in. 

 long: achenes of the ray broadly obcompressed, rounded at summit, 

 beakless. — Eastern slope of the Sierra, from Mariposa Co. northward. 



58. MADARIA, DeCandolh. Erect glandular-hairy pilose or some- 

 what hispid annuals with somewhat corymbosely pauicled heads of 

 showy yellow vespertine flowers; the foliage lanceolate, never divided, 

 usually entire. Receptacle convex, densely fimbrillate-hirsute, usually 

 with only a circle of bracts between ray and disk. Achenes of ray com- 

 pressed, not incurved, of disk abortive, all destitute of pappus. 



1. M. elearans, DC. Prodr. v. 692 (1836); Don, in Bot. Reg. t. 1458 

 (1831), under Madia. Stout, 3—5 ft. high, with scattered lanceolate 

 leaves entire or serrate, sessile by a broad base; whole herbage viscid 

 with abundant stalked glands or short gland-tipped hairs, the peduncles 

 and involucres copiously hirsute with long white hairs: heads numerous 

 in an ample corymbose panicle: rays 12— 15, nearly 1 in. long, yellow, 

 often with dark red base: achenes rather thin and flat, dark-brown or 

 blackish. — Frequent in partly shaded ground among the hills and lower 

 mountains of middle Calif, toward the coast. Aug. — Oct. 



2. M. densifolia. Madia densifolia, Greene, Pitt. iii. 167 (1897). In 

 size and in floral characters like the preceding, but leaves all very 

 narrowly linear and entire, densely short-hirsute without glands, 4 — 8 in. 

 long and crowded upon the basal portion of the tall stem, the much 

 reduced and scattered cauline leaves and rameal bracts sparsely bristly- 

 ciliate with hairs longer than the width of the leaf: the ample rays often 

 red at base; achenes less flattened than in the last, being distinctly 

 compressed-trigonous. — Same range with M. elegans, but in more open 

 ground; extremely distinct from, and more common than M. elegauii, 

 with which it has long been confused, and for which I mistook it 

 formerly; this being exactly the Madia elegans of the Bay Region 

 Manual, but by no means that of Don. July — Oct. 



3. M. hispida, DC. Prodr. v. 692 (1836); Greene, Pitt ii. 217 (1891),
