Persistent petals at length somewhat scarious. Filaments exceeding the anthers. 

 Ovary 3 - 6-carpelled, the short style bearing as many cordately 2-lobed capitately 

 crowded stigmas. Capsule dehiscent to the middle. Seeds oblong, with the rhaphe 

 carunculate-crested. Gray, Proc. Amer. Acad. xii. 52, t. 2.

Sepals 3, caducous. Petals 6, persistent, at length scarious and enwrapping the 

 capsule. Stamens 6 to 9 ; filaments shorter than the oblong-linear anthers. Ovary 

 subglobose, 3-carpelled, with nerve-like many-ovuled placentas : stigmas sessile, 

 linear-oblong, appressed to the ovary over the placentas. Capsule ovoid, membra- 

 naceous, 3-valved, the valves separating to the base from the persistent filiform pla- 

 centas. Seeds several, very smooth and shining, narrowly oblong-obovate and slightly 

 curved ; rhaphe naked. Embryo very small, cylindrical. A dwarf glabrous annual, 

 with alternate linear entire leaves and numerous filiform 1 -flowered scapes. Gray,

1. C. Candida, Parry. Scarcely an inch high, densely much branched, the 

 small somewhat fleshy leaves and very short branches closely crowded : flowers 

 white, the petals hardly 2 lines long. Gray, 1. c. 



San Bernardino County, in sandy soil at head of the Mohavc River, Dr. E. Palmer, May, 1876. 

 Nearly allied to Arctomecon, and with that genus peculiar in its persistent scarious petals. The 

 stigmas are essentially similar in both, in this genus divaricately divided to the base, the adjacent 

 lobes coherent and applied over the placentas.

1. D. formosa, DC. In Del Norte County (Rattan), with yellowish white 

 flowers. The seeds in this species are either smooth and shining or tuberculate and 

 dull. Inner petals with a conspicuous usually purple or purplish crest. 



2. D. uniflora, Kell. Flowers half an inch long, the divergent or reflexed tips 

 of the outer petals equalling or exceeding the erect gibbous-saccate bases ; inner petals 

 not crested, the blade broadly hastate : capsule not exserted, abruptly beaked with 

 the short style. 



2 a . D. pauciflora. Scapes and leaves very slender, 4 to 8 inches high, from a 

 running tuberiferous rootstock : leaves biternate with narrow segments : flowers 

 1 to 3, white or more or less tinged with rose-color, 8 to 12 lines long, the short 

 stout straight spurs not divergent; spreading or reflexed tips of the outer petals 

 3 or 4 lines long ; inner petals obscurely crested, the blade not broader at base : cap- 

 sule exserted, attenuate into the elongated style. 



Scott Mountain^, near snow (Rev. E. L. Greene) ; near Castle Lake, J. G. Lcmmon. Flower- 

 ing in July and August. 



2. CORYDALIS. 



1. C. Caseana, Gray. Leaflets very variable in size, to 1 inch long, acute : 

 hood of outer petals with straight slightly erose-undulate margin, obtusish and bear- 

 ing a rather broad obtuse erose crest : capsule acute, ascending or reflexed. 



2 a . C. BidweUiae. Similar in habit : leaflets small (2 to 4 lines long), acute 

 or acuminate : hood narrower with somewhat more spreading and ragged margin,
