h— h— Validiores, viscidos ; foliis rigidis superioribus proesertim a 

 basi dilatatis, lobis dentibusve spinulosis vel spinosis : capitulis 

 densis. 



29. G. viscidula. Nav. viscid ula, Bcnth. PI. Hartw. — Apparent- 

 ly common and widely spread in California. The lobes of the calyx 

 more usually entire. It is described as with solitary ovules in the 

 cells ; but two are more commonly found, even in Hartweg's speci- 

 mens ; while in robust forms of what is otherwise indistinguishable 

 from the species, collected by Bridges, Fitch, Samuels, Bolander, &c, 

 there are three or four ovules in each cell ! 



30. G. atracttlOides. New. atractyloides, Hook. & Arn. — Cali- 

 fornia, from Monterey to San Diego. 



-^ — -*- — -*- — Depressa;, parum viscidae ; foliis rigidis versus apicem dila- 

 tatis, dentibus lobisve cum calycis segmentis longe setiferis ; flori- 

 bus vix congestis.

 Ives Colorado Exped. p. 22. Ovula in loculis G - 10. — Var. exigua, 

 ovulis in loculis 3-5. N. Schottii, Torr. Bot. Mex. Bound, p. 145. —

§ 7. HUGELIA. Flores capitato-glomerati, crebre foliaceo-bracteati ; 

 bracteis 3 - 5-fidis basi calycibusque lana longa implexa albida 

 vestitis, lobis utriusque acerosis subulatisve cuspidatis. Corolla 

 plerumque caerulea hypocraterimorpha, tubo gracili, lobis saspius 

 oblongis. Antheroa exsertas, nunc lineari-sagittata;, nunc breves. 

 Ovula numero perquam variabilia ! — Plantar humiles, juniora 

 proesertim floccoso-lanatae, baud viscidaa, foliis semel pinnatiparti- 

 tis paucisve integris acerosis vel subulato-filiformibus. — Hugelia, 

 Benth. in Bot. Reg. Gilia sect. Collomioides (Endl.) & Pseudo- 

 collomia, Benth. in DC. 



In this group I can make nothing of the number of the ovules, even 

 as a specific character. In two specimens apparently exactly alike, one 

 has three or four, the other only two, ovules in each cell : sometimes 

 there is a pair in one or two of the cells, and a solitary one in the 

 other. In none have I detected the maximum number mentioned in the 

 Prodromus, i. e. ten in each cell. The Hugelia lidea, Benth., probably 

 had not yellow flowers. The tube of the corolla lengthens with age in 

 all the species. Gilia gossypifera is better placed in the next section.
