450 SUPPLEMENT. 



F. flexuosa, GRAY. Widely branched from a woody base, canescently puberuleiit or gla- 

 brate in age : branches slender, flexuous : leaves coriaceous, short-petioled, deltoid-lanceolate 

 and laciniate-dentate, or upper lanceolate with cuueate base, feather-veined, the tapering tip 

 and coarse teeth somewhat sphmlose : heads naked-paniculate on the branches : fertile invo- 

 lucres pubescent, armed with 7 or 8 stout-subulate and widely spreading straight spines, 

 2-3-flowered. Proe. Am. Acad. xx. 298. Canon Cautillas, within the borders of Lower 

 California, Orcutt. 



P. chenopodifolia, BENTH. To stand between F. dtltoidea and F. eriocentra, habit of the 

 former : leaves broadly ovate or subcordate, rather slender-petioled, crenate-serrate, rarely 

 somewhat incised, an inch broad, minutely white-tomentose, upper face glabrate: fertile in- 

 volucres glomerate, subglobose, 2-3-flowered, tomeutose-lanate, but the numerous subulate 

 divergent spines naked. Bot. Sulph. 26. All Saints Ba/, in Lower California, Orcutl. 

 Hinds found it farther south, at Bay of Magdalena. Probably may reach the U. S. border. 



101. G-YMNOL6MIA, HBK. 



G. triloba, GRAY, p. 2G9, has a thick perennial root, and should be transferred to the second 

 division, after G. tenttifolia. 



G. encelioides, GRAY, and the division under which it stands, are to be suppressed, as also 

 Viguiera tephroJes, p. 271. See Hclianlhus, infra. 



104. HELlANTHUS, L. After H. deUlis, p. 273, add : 



H. tephrodes, GRAY. Annual, strigose-canescent, or the stem and branches more loosely 

 hispidulous: leaves ovate lanceolate or ovate-oblong, obscurely denticulate or entire (an inch 

 or two long), soft strigose-canescent both sides, rather long-petioled : heads short-peduncled : 

 involucre 4 or 5 lines high, of oblong-lanceolate acute bracts : rays broadly oblong : bracts 

 of the receptacle nearly entire and glabrous: akenes linear-oblong, thickish, silky -hairy at 

 least above : pappus of two oblong or linear caducous small and thin palete, which some- 

 times do not surpass the hairs of the akeue. Bot. ilex. Bound. 90, & Proc. Am. Acad. xx. 

 298. Viguiera nivea, Gray, Bot. Calif, i. 354, excl. syn. V. tephrodes, Gray, & Gi/mnolomia 

 encelioides (Proc. Am. Acad. xix. 4), Gray, supra, 269, 271. Southern borders of California 

 and Arizona about the head of the Gulf, Scltott, Parish. (Adj. Sonora, Prinqle.) 

 H. Oliveri, GRAY. Perhaps next H. Par/shii, p. 277, tall and stout (10 or 12 feet high), 

 leafy to the top, remarkable for its soft-villous and even tomeutose pubescence and no rough- 

 ness: leaves all alternate, lanceolate (4 to 7 inches long), tapering to an acute point, and at 

 base into a short and margined petiole, nearly entire, obscurely triplinerved near the base : 

 involucre also villous, of linear-subulate bracts, not surpassing the disk : rays an inch long : 

 palese of the pappus subulate from a broad base. Proc. Am. Acad. xx. 299. S. Califor- 

 nia, in low grounds between Los Angeles and Santa Monica, J. C. Oliver. 

 H. DEALsAxus, Gray, p. 280. Collected in excellent specimens by E. L. Greene, 1885, on 

 Cape San Quentiu, Lower California; the foliage very silvery and soft with the dense panuose 

 tomeutnm. From the habitat, the Encelia-like aspect, and the whole description, this is evi- 

 dently Encella nicea, Beuth. Bot. Sulph. 27, the new specimens with peduncles even longer than 

 described, and the bracts of the involucre come near to ovate-lanceolate. The small and narrow 

 paleaa of the pappus are so very caducous from the ovary that Beutham overlooked them. 



107. HELI ANTHfiLL A, Torr. & Gray. 



H. Californica, GRAY, p. 285. Add syn. : If. Neradensis, Greene, Bull. Calif. Acad. i. 90, 

 the state with small awns and intermediate exiguous squamellaj more developed ; but traces 

 of both are found in the original of coll. Bigelow, sometimes whole pappus obsolete from 

 the first. 



118. BALDWlNIA, Nutt. 



B. Uniflora, NCTT., p. 302. Add syn. : Viguiera glandulosu, Bertol. Misc. Bot. vii. 45.
