Rocky Mountains in Upper California, about lat. 42°, Nuttall! Near
the Blue Mountains and on Snake River, Mr. Tolmie.—Leaves sometimes
toothed only towards the base, about the length of the calyx-tube. Flowers
large and handsome. Capsules an inch long (the pedicel about the same
length) coriaceous, hairy. Seeds ovoid, gibbous, appearing grooved along
the inner side by the appendage or fold of the testa on each side of the
raphe, extending* from near the hilum to the chalaza.
* * * * * * Decumbent caulescent perennial herbs: flowers (very large) erect
before expansion, diurnal, yellow, scarcely odorous: tube of the calyx very
long, thick, slightly and gradually dilated near the summit: capsule pedicellate,
smooth and shining, veinless, coriaceo-membranaceous, tardily dehiscent,
somewhat compressed, very broadly A-winged: seeds ascending, in a single
row in each cell, oval-obovate, with a crustaceo-membranaceous testa, appendi-
culate with a double membranaceous crest along the inner side from near the
base to the chalaza.—Megapterium, Spach. 26
26. CE. Missouriensis (Sims): stems simple, decumbent: leaves coriaceous,
lanceolate, acute, tapering into a short petiole, obscurely denticulate,
somewhat canescent when young ; flowers axillary (very large); segments
of the calyx much shorter than the tube, about the length of the roundish-
flabelliform mucronulate petals; stamens and style arcuate-declined; capsules
pedicelled, very large, somewhat compressed, with 4 broad wings.__

Dry hills, throughout Missouri! and on the Canadian River, Dr. James !
July-Oct.—Stems low. Tube of the calyx 4-7 inches in length; the segments
acuminate, often spotted with purple. Corolla 4-6 inches in diameter
; the petals very broad, light yellow, with orange veins. Capsule 2
inches in length, and about the same breadth, including the wings; but
exclusive of the wings only a quarter of an inch in diameter. Seeds large;
the undulate crest conspicuous, especially at the chalaza.
§ 2. Stigma dilated, disciform,,, obscurely A-lobed: tube of the calyx much
produced, trumpet-shaped ; the segments short, not carinate : petals broadly
rhombic-ovate, erose-crenulate : stamens erect, slightly unequal: anthers oblong
linear, fixed near the middle, versatile: capsules short, cylindrical,
sessile: seeds in a double series, horizontal: stems suffrutescent: flowers
(rather large, nocturnal?) yellow turning to rose-color, erect before expansion.—

27. CE. lavandulxfolia: suffruticose, low, decumbent, somewhat canescent ■
leaves crowded, linear, entire, obtuse; tube of the calyx tubular-infundibuli-
form, many times longer than the ovary and the ovate-lanceolate slightly acuminate
segments; petals rhombic-ovate, crenulate, longer than the stamens •

Plains of the Platte, Dr. James ! Nuttall! (“ near Scott’s Bluffs.”)—Root
large, woody. Stems simple, about a span in length. Tube of the calyx
about 2 inches long. (Seeds in two rows in- each cell, horizontal. N u tt)
—Very nearly allied-to the Mexican CE. Hartwegi, Benth., which is a more
glabrous plant, with narrower leaves, a more slender calyx tube, and subulate
acuminate segments: the stigma however is similar. We have not
seen the fruit of either species.
§ 3 . Stigma disciform, crenulate: tube o f the calyx infundibulifarm, strongly
A-nerved, shorter than the ovary : the segments carinate with the mid-nerve:
petals obovate, erose-crenulate: stamens short, erect: the filaments opposite
the petals shortest: anthers oblong, fixed by the middle, versatile : capsules
cylindrical, linear, sessile, coriaceous, nearly even: seeds ascending, in a
double series : the testa thin: stems suffrutescent at the base: flowers (rather
small, diurnal ?) yellow, erect before expansion.—Calylophis, Spach.

rigid, linear, lanceolate or oblaneeolate, attenuate at the base, irrejmlarly and
sharply denticulate-serrate : flowers axillary; petals obovate, undulate-
crenulate, inserted by a broad base, much longer than the stamens and the
cannate calyx-segments ; stigma discoid ; capsules cylindrical or slightly
prismatic, slender, somewhat 4-grooved. — Calylophis Nuttallii! Drum-
