icels short or hardly any in the forks ; the lateral often as long as the flower, but 2-bracteo- 

 late at summit : lobes of the rose-red corolla oval, very obtuse or retuse, in age merely 

 oblong, 2 or almost 3 lines long: seeds short-oval. DC. 1. c. 60, as to California plant 

 only ; Bentli. PI. Hartw. 322 ; Gray, Bot. Calif, i. 480. Western part of California, and

E. Douglasii, Gray. Slender, a span to a foot high, loosely and panieulately branched, 

 usually sparsely flowered : leaves from oblong to linear, mostly acute : flowers all on strict 

 and slender 1 peduncles or pedicels : lobes of the pink corolla oblong, obtuse, at most 2 lines 

 long, nearly half the length of the tube: seeds globular. Bot. Calif, i. 480. E. Nuttallii,

E. Nuttallii, "Watson. Like the preceding : lobes of the rather larger corolla more 

 ovate, acutish, sometimes nearly 3 lines long: seeds fewer, and much larger (a third of a 

 line long), oblong. Bot. King, 276, t. 29, mainly. Nevada, Idaho, and Utah, Nuttall, H. 

 Enr/clmann, Watson. 



H- -H- Flowers larger: corolla-lobes HJ to G lines long, but more or less shorter than the tube : 

 anthers linear. 



= Corolla-lobes narrow, in age by involution becoming acuminate: branching and inflorescence 

 fastigiatc-cymose : lilaments and style very slender. 



E. trichailtha, Griseb. A span or less high : leaves from oblong-oval to lanceolate : 

 flowers in dense cymes, those in the forks all sessile or nearly so : corolla-lobes oblong- 

 lanceolate becoming linear-lanceolate, 3.^ or 4 lines long : stigmas small : seeds oval-oblong.

E. Beyrichii, Torr. & Gray. A span to a foot high, slender, at length fastigiately 

 much branched: leaves linear (an inch or more long, a line or much less in width), the 

 uppermost nearly filiform : flowers very numerous and all pedicellate : corolla-lobes linear- 

 oblong and becoming linear, 5 lines long: seeds globular. Torr. in Marcy Rep. 291, t. 13.

= = Corolla-lobes broader and obtuse, little shorter than the tube : inflorescence loose : flowers 

 all pedicellate : seeds globular. 



E. calycosa, Buckley. Panieulately or somewhat cymosely branched, a span to 2 feet 

 high : leaves from narrowly oblong to lanceolate or linear : pedicels mostly as long as the 

 calyx or the whole flower: lobes of the corolla oval or oblong, 34- to 5 lines long ; the tube 

 usually equalled by the calyx. Proc. Acad. Philad. 1862, 7. W. Texas and New Mexico, 

 Wrir/ht, Buckley, &c. (Adjacent Mex.) 



Var. liana. A span high, with leaves all linear and inflorescence corymbose-cymose : 

 approaching E. Beyrichii, but corolla-lobes only 3 or 4 lines long and broadly oblong. 

 Stony hills, W. Texas, Wri;/ht (no. 1662), Woodhouse. 



Var. Arizonica. Stems or branches a foot or so long, lax : inflorescence racemosely 

 paniculate or as if racemose : calyx-lobes mostly shorter than the tube of the corolla. 

 S. Utah and Arizona, Wheeler, Palmer, &c. 



E. venusta, Gray. A span or so high : leaves from ovate to oblong-lanceolate : flowers 

 somewhat cymose or paniculate, on short or sometimes long pedicels : lobes of the corolla 

 oval or obovate, becoming oblong, deep pink, 4 to 6 lines long, about the length of the yel- 

 lowish tube, which is equalled by the calyx. Bot. Calif, i. 479. E. tric/xuitha, Durand in

3. S ABB ATI A, Adans. (Liberatus Sabbat i, an early Italian botanist.) 

 Atlantic North American biennials or annuals ; with mostly showy rose-colored or 

 white flowers (in summer and autumn), terminating the branches or in cymes. 

 Calyx in most species deeply parted. Corolla usually with a yellowish or dis- 

 colored eye. Style closed in early anthesis, and commonly turned to one side 

 of the flower (and sometimes spirally twisted), later erect and its branches or 

 stigmas diverging. Seeds very numerous and small, globular, pitted.
