terininal and long-peduncled from the upper axils, nodding in fruit, 

 10-12 mm. high; scales 2-.3-rowed, loose, lanceolate, somewhat 

 glandular, ciliate and tomentose; rays about 12, oval, subentire, 

 7 mm. long, with hairy tube; disk-corollas as in the last, glandular 

 at l)ase and tip, 5 mm. long; pales few-nerved, glandular-hairy 

 toward the loose subherbaceous tip, 8-10 mm. long; achenes 5-6.5 mm. 

 long, obovate, emarginate at apex, densely spreading-villous on the 

 margin and with a few hairs toward the apex. 



Encelia laciniata Vasey & Rose, Proc. U. S. Nat. Mus. xi. 535 (1889). 



Specimens examined: Lower California: sand plains and hills 

 above the bay. Lagoon Head, 6-15 Mar. 1889, Palmer 804 (FGN, type 

 collection); Ascension Island, Mar.-June 1897, Anihony 435 (G). 

 Also reported by Brandegee from San Gregorio. — Anthony's plant 

 differs from Palmer's in its thicker more bluntly lobed leaves, like the 

 stem finely glandular-pubescent, nearly without the rough white 

 hairs of the types. 



* * Halimifoliae. Herbaceous or frutescent; leaves entire or merely 

 repand-toothed, oblong to ovate; disk yellow or purple; achene rarely 

 with 1 or 2 weak awns. 



•*- Heads numerous, paniculate, the branches of inflorescence smooth; leaves 



chiefly basal. 



3. E. farinosa Gray. Much branched from a woody base, 

 sometimes 1.6 m. high, the stems and branches exuding a fragrant 

 resin, white-mealy becoming glabrate; leaves mostly basal, broadly 

 ovate to lanceolate, acute or obtuse, entire or rarely repand-toothed, 

 the margin often undulate, densely white-farinose occasionally be- 

 coming subglabrate, the nerves rather prominent beneath, 3-10 cm. 

 long, 2-5 cm. wide, on narrowly margined petioles 1-4 cm. long; 

 panicle nearly naked, the branches whitish-yellow, glabrous or rarely 

 with a few hairs, often glandular-hairy just below the heads; heads 

 terminating the branches, often nodding in fruit, radiate, disk 1-1.5 

 cm. in diameter; scales imbricated in 3-4 rows, the outer or some- 

 times all linear, the inner usually successively longer and with broader 

 bases, loosely hairy when young, often glabrate when older, all blunt, 

 the longest 3.5-7 mm. long, shorter than the disk; rays ^^ about 12, 

 usually conspicuous, 7-11 mm. long, oval-oblong, 3-lobed; disk- 

 corollas 3.5-4.5 mm. long, glandular on the tube, yellow including the 

 limb; pales 6-7 mm. long, glandular on keel, faintly nerved, entire 

 or laterally 1 -toothed; achene 4.5 mm. long, obovate, emarginate, 

 villous all over except for a submarginal naked border, awnless. 



33 In Coulter 327 (hb. Gray) some at least of the rays are styliferous, the 

 only such instance known to me in the genus.
