14 FUMARIACE.E. (FUMITORY FAMILY.) 



1. DICENTBA, Borkh. 



Sepals 2, small and scale-like. Petals 4, in two sets ; the outer pair larger, 

 saccate at base, the tips spreading ; the inner much narrower, spoon-shaped, 

 the hollowed tips lightly united at the apex, thus forming a cavity which con- 

 tains the anthers and stigma. Middle anther in each set 2-celled, lateral ones 

 1 -celled. Stigma 2-lohed. Pod 1-celled. — Glabrous perennials with the 

 fleshy root surmounted by a bulb-like cluster of fleshy grains and ternately 

 or pinnately compound leaves. 



1. D. uniflora, Kellogg. The 3 to 7 divisions of the leaves pinnatifid 

 into a few linear-oblong or spatulate lobes : scape 2 to 3 bracted, 1-flowered : 

 flowers flesh-colored, J inch long, the divergent or reflexed tips of the outer 

 petals equalling or exceeding the erect gibl lous-saccate base ; inner ones not 

 crested, the blade broadly hastate : pod abruptly beaked with the short style. 

 — Alpine. Wasatch and Teton Mountains, and westward in the Sierra 

 Nevada. 



2. COEYDALIS, DC. 



Corolla one-spurred at the base on the upper side. Otherwise as in Dicentra. 

 * Corolla golden-yellow ; spur shorter than the rest of the flower. 



1. C. aurea, Willd. Stems low or decumbent: racemes simple: the 

 slightly decurved spur not half the length of the rest of the flower : tips of the 

 outer petals blunt, crestless and naked on the back: pods usually pendent: 

 seeds smooth and even, turgid, marginless, partly covered by the scale-shaped 

 aril. — From Colorado northward and eastward. 



Var. OOcidentaliS, Gray. Spur longer : pods erect : seeds lenticular with 

 acute margins. — More common in our range than the type. Colorado to 

 Montana, and eastward to Missouri and Texas. 



Var. mierantha, Engelm. Flowers small, nearly spurless, on short pedi- 

 cels: pods ascending. — From the Western Mississippi States to the Uinta 

 Mountains. 



2. C. CUXVisiliqua, Engelm. Differs from the last in having longer 

 i-angular pods ascending on very short pedicels : the acute-margined seeds muri- 

 cnte. — C. aurea, var. curvisiliqua, Gray. Common in the mountains of 

 Colorado and southeastward. 



* # Corolla white or cream-color ; spur longer than the rest of the flower. 



3. C. Brandegei, Watson. Tall and stout (5 feet high) : leaves twice 

 or thrice pinnately divided ; the lanceolate leaflets i to 1 inch long, acute or 

 acuminate : hood not crested, the margins folded back and not projecting 

 beyond the obtuse summit: pod oblong-obovate, obtuse, reflexed. — Mountains of 

 S. Colorado and in the Wasatch. Formerly referred to C. Caseana, which 

 nas a more westerly range. 



4. C. Cusiekii, Watson. Leaves bipinnately divided ; the oblong-oval leaf- 

 lets acute at each end, half-inch long : the broad margins of the hood produced 

 beyond its acute apex and folded bach over the narrow and somewhat crisped 

 or erose crest : pod acute y — Extending from Oregon into the Bitter Root 

 Mountain*.
