5. E. pusilla, (Jmy. Soft-pubescent, an inch or two hi^^li, erect, at lengtli 

 branched from the base : leaves oblong-lanceolate or spatulate, 2 to 5 lines long and 

 with slender petiole of equal length : flowers 3 to 7, scattered in a tilifcjrin loose 

 raceme, the primary one scapiform ; pedicels spreading : corolla about half the 

 length of the linear and obscurely spatulate calyx-lobes and also of the ovoid very 

 obtuse and pointless capsule : style very short and deciduous. — Proc. Am. Acad, 

 xi. 87. 



Northwestern Nevada, Watson (young specimens, taken for a state of Pliacclia pimlla), also 

 Lemmoii. Calyx in blossom one Une, in fruit 2 lines long. Corolla apparently white, persistent, 

 investing the base of the capsule. Seeds strongly corrugated. 



§ 2. Larger, with loose paiiicled racemes : seeds coarsely pitted : calyx-lohes hroader 

 doumivard : style deciduous : co7-olla cream-colored, with short rounded lobes, 

 destitute of appendages. — Emmenanthe proper. 



6. E. penduliflora, Benth. A span to a foot high, villous-pubescent, some- 

 what viscid : leaves pinnatifid ; the lobes numerous, short, somewhat toothed or 

 incised : pedicels tdiform, at base sometimes bracted, as long as the at length nod- 

 ding flowers : filaments almost free from the broadly campanulate unwithering 

 corolla : ovules about 16. 



Open ground, not rare from Lake Co. to San Diego, extending east to Southern Utah. Flowers 

 handsome : corolla almost half an inch long. Seeds a line long. 



7. CONANTHUS, S. Watson. 



Calyx deeply 5-parted, the lobes very narrow and similar. Corolla funnelform, 

 not appendaged, deciduous. Stamens unequally inserted more or less high on the 

 tube of the corolla : filaments slender. Style 2-cleft at apex, sometimes nearly 

 entire: stigmas capitellate. Ovary and capsule 2-celled, 10 - 20-seeded. Seeds 

 with a thin and translucent coat, nearly smooth, the sides obscurely rugose or 

 excavated when mature. — Watson, Bot. King Exp. 256; Gray, Proc. Am. Acad.

1 . C. aretioides, Watson, 1. c. A small and depressed winter-annual, repeatedly 

 forked from the very base, two or three inches high, soon forming a matted ttift, 

 hirsute-hispid, flowering copiously a long time : leaves spatulate-linear (an inch 

 or less long) : flowers sessile in the forks, half an inch long : corolla with a nar- 

 row tube and rather ample limb, piirple. — Eutoca aretioides, Hook. & Arn. Bot. 

 Beechey, 374 ; Hook. Ic. PI. t. 355. 



Dry eastern side of the Sierra Nevada, and adjacent portions of the interior region, from Oregon 

 to Arizona. Plant with mostly the characters of Nama, except the united styles. Stamens and 

 style varying in length and height of insertion, apparently from dimorphism. 



8. TRICARDIA, Torr. 

 Calyx-lobes or sepals very dissimilar, three outer ample and round-cordate, thin- 

 herbaceous, enlarging and becoming scarious and reticulated with age ; the two 

 inner small and linear. Corolla broadly campanulate, deciduous ; internal appen- 

 dages 10 narrow plaits, free and rather distant from the unequal filaments. Style 

 2-cleft. Ovary glabrous, incompletely 2-celled : ovules 4 to each placenta. Flowers 

 racemose, rather few : corolla purplish. — S. Watson, Bot. King Exp. 258, t. 24. 



1. T. Watsoni, Torr. in Bot. King, 1. c. A low perennial, branched from the 

 base, a span high, cottony-pubescent, but nearly glabrous when old : leaves all alter- 

 nate, entire ; the radical and lower cauline spatulate-lanceolate (one or two inches 

 long) and tapering into a margined petiole ; the upper mucli smaller and more
