CORYDALIS. CRUCIFER.A. 35 
inch or less long, the nearly straight spur fully twice as long as. the rest of 
the flower; hood of the outer petals emarginate by the development of 
broad thin margins which are recurved over the narrow and undulate dor- 
sal crest: capsule oblong, turgid, 6 lines long: seeds nearly smooth, with a 
conspicuous orbicular carunculate crest. Along alpine streams, Blue and 
Eagle creek Mountains, eastern Oregon to western Idaho. 
§ 2. Biennials, mostly branched from the base, with finely 
dissected leaves and siliquiform capsule. 
C. aurea Willd. Enum. 710. Commonly low and spreading: flowers 
golden yellow about half an inch long, on rather slender pedicels in a short 
raceme: spur barely half the length of the body when dry, 10-12-seeded. 
seeds turgid obtuse at margin, the shining surface obscurely reticulated. 
Rocky banks, eastern Oregon to Brit. Columbia, Lower Canada and 
northern New England (Gray, Syn. Fl. 7, 97). 
€. montana Engelm. in Gray, Pl. Fend. 8. Stems decumbent, 6-12 
- inches long: leaves pinnate, leaflets 5-7 parted, the divisions irregularly 
laciniate-toothed : flowers yellow, in short-peduncled racemes; spur shorter 
than the rest of the flower: capsule 4-angled, deflexed in fruit: seeds 
acutely margined muricate. From the Blue Mountains of Oregon to west- 
ern Idaho and Mexico. 
Orver VII. CRUCIFER& Endl. Gen. 861. 
Herbs rarely suffrutescent, with pungent watery juice, cruci- 
form corolla tetradynamous stamens and 2-celled pod (silicle or 
silique) with two parietal placente. Flowers perfect. hypogyn- 
ous. Sepals 4, often colored, deciduous. Petals 4, usually with 
narrow claws and spreading lamina, rarely, wanting. Stamens 6, 
two of them inserted lower down on the receptacle and shorter 
than the other 4. Ovary 2-celled by a partition which stretches 
across from the placente or the partition, rarely wanting. Style 
undivided or none: stigma entire or 2-lobed. Ovules few or nu- 
merous, camplytropous. Seeds smooth, without albumen. Cuty- 
ledons either accumbent applied edgewise to the radical or incum- 
bent, with the radical against the back of one of them or sometimes 
conduplicate, plicately folded and partly enveloping the radical. 
Inflorescence racemose orspicate or somewhat corymbose and 
. (with rare exceptions) ebracteate. 
Serres 1. Pods 2-valved, dehiscent their whole length (except 
in Brassica), not compressed contrary to the partition. 
_ Tre tr. Fruit completely or incompletely 2-celled, regu- 
larly dehiscent, flattened parallel to a broad partition, terete. or 
prismatic, short or long. | 2 
* Pods more or less strongly compressed parallel to the partition. 
1 Parrya. Pods lanceolate, acuminate; valves flat, with a prominent 
ae nerve and reticulated: seeds in 1 row in each cell, large, not 
winged. x ; : 
2 Cheiranthus. Pods strongly compressed, 1-4 inches long, -broadly 
linear, with flat 1-nerved valves or narrow and quadrangular with con- 
vex and more or less distinctly keeled valves. 
** Pods globose terete or prismatic, at least not compressed parallel 
to the partition. 3
