Smooth slender glaucous an nuals, with finely dissected leaves, bright 
orange or yellow flowers, Sepals coherent into a pointed hoad which 
Speedily falls off entire from a dilated top-shaped receptacle, 4 petals, 
and elongated strongly 10-nerved pods which open their whole length. 
1, E. Mexicana Greene. Dwarf and rather stout: leaves with crowded lobes: 
peduncles 5 to 25 em. long, mostly scapiform: petals orange-yellow, broad, 12 to 25 
mim. long. (E. Douglasii, var. parvula Gray.)—The most eastern species, barely 
entering extreme western Texas along the Rio Grande. 
FUMARIACE. (FuMItoRyY FAMILY.) 
Delicate smooth herbs, with compound dissected leaves, irregular 
flowers, 2 small scale-like sepals, 4 petals in 2 pairs, the outer with 
Spreading tips and one or both Spurred or saceate at base, the inner 
with callous crested tips united over the stigma, 6 stamens in 2 sets of

1. CORYDALIS Vent. 
Ours are biennial leafy-stemmed pale plants, with yellow flowers in 
racemes, corolla 1-spurred at base, and pod with many-crested seeds. 
* Hood or saccate tip of outer petals crestless, the back at most carinate: flowers golden- 
yellow. 
1. C. aurea Willd. Commonly slender and with spreading pedicels: spur of corolla 
barely half the length of the body, somewhat decurved: pods pendulous or spread- 
ing, terete, torulose when dry: seeds turgid, with obtuse margin.—One of the early 
bloomers, on sandy ground throughout Texas. Var. OCCIDENTALIS Engelm. is more 
erect and cespitose, stouter, with rather larger flowers in a stouter erect raceme, 
spur almost as long as the body and commonly ascending, pods thicker, less toruluse, 
mostly incurved, ascending on short spreading pedicels, and seeds less turgid, with 
acutish margins. (C. montana Eng.)—Southern and western Texas, 
2. C. curvisiliqua Engelm. Habit of preceding variety, and with spiciform 
raceme of rather larger flowers, the spur as long as the body: pods quadrangular, 
ineurved and ascending or straightish on very short and stout diverging pedicels: 
seeds turgid-lenticular, with acute margins.—Sonthern (near New Braunfels) and 
western Texas, Well marked by its tetragonal pods, 
** Hood or saccate tip of outer petals dorsally wing-crested : Jlowers pale yellow and short 
spurred, 
3. C. micrantha Gray. Stems diffuse and slender: flowers short-pediceled and 
small-bracted, when full-developed 8 mm. long, with spur 2 to 4 mm, long: often 
with only cleistogamous and much smaller flowers, which are spurless and crestless, 
or only slightly crested: pods linear and slender, torulose, ascending on short or 
very short pedicels: seeds turgid, with obtuse margin. (C. aurea var. micrantha 
Engelm.)—A species of the Gulf States extending into Texas, possibly as far west 
as our eastern limit. 
CRUCIFERE, (Mustarp FAMILY.) 
Herbs, with a pungent watery juice, alternate leaves without sti-
