angustioribus solitariis. — Commoner southward in California, especial- 

 ly forms with the scape inflated, of which Prof. Brewer collected seve- 

 ral, some of them with all the involucres solitary and almost as in the 

 section Virgata. 



33. E. elatum, Dougl. 1. c. Foliis mollissime villoso-pubescentibus 

 vel subtus fere velutinis ovato-oblongis sublanceolatisve basi (raro sub- 

 cordatavel subhastata) in petiolum angustatis; scapo cum panicula rigido; 

 involucris magis turbinatis repando-5-dentatis, alaribus nonnunquam 

 solitariis longius pedicellatis, caeteris nunc potius glomerato-congestis 

 quam capitatis ; perigonio basi extus pilosulo. — Washington Territory 

 to California and Nevada, on plains. The pubescence of the flower is 

 variable in degree, but not wanting as described by Bentham. South- 

 ward the scape is sometimes inflated. 



§ 9. Fasciculata, Benth. olim. Flos, etc. prrecedentium. Ovarium 

 glabrum. Involucra (truncata subdentata, dentibus membranula 

 primum connexis) perpluriflora, in capitula vel cymulas capituli- 

 formes congesta, capitulis pi. m. bracteatis pedunculos dichotomos 

 vel cymoso-umbellatos terminantibus, alaribus (aut ramo altero 

 abortiente lateralibus sessilibus. Bracteolos plumosaa. — Suffru- 

 tices foliosi, foliis parvulis alternis et in axillis fasciculatis subtus 

 incanis margine sa?pius revolutis ; floribus albis nunc roseo tinctis, 



* Extus sericeo-villosis baud numerosissimis. Folia minus conferta. 

 Embryo subrectus, radicula gracili in cotyledonibus ovalibus par- 

 vulis leviter inflexa. 



34. E. cinereum, Benth. Bot. Sulph. p. 45, & in DC. 1. c. Fruti- 

 cosum, laxe ramosum, pube tenui canescens ; foliis secus ramos subfas- 

 ciculatis ovatis margine undulatis minus aut vix revolutis subtus incanis 

 breviter petiolatis ; pedunculis elongatis junciformibus fere nudis su- 

 perne dichotomis ; capitulis paucis laxiusculis. — California, San Pedro, 

 Hinds or Barclay ; Santa Monica, on sands of the sea-shore, " a shrub 

 three to five feet high, forming dense patches," Brewer. Leaves vary- 

 ing from orbicular to obovate, ovate, and almost oblong, from half an 

 inch to an inch in length, mostly with a distinct short petiole. Coty- 

 ledons oval, somewhat excentric, barely twice the breadth and little 

 more than half the length of the slightly inflexed radicle. 



* * In involucris numerosissimis, demum secus axin elongandum 

 baud raro quasi racemosis, extus glabris vel pilosulis. Suffrutices, 

 ramis creberrime ac fasciculatim foliosis. Folia parva margine
