AA PLANTHE FENDLERIANE. 
the Rio del Norte; May, — Corolla often 2 inches in diameter, pure white turning to 
rose-color, Some of the specimens are only two or three inches high, and just beginning 
to blossom; the radical leaves oblong or spatulate and entire: others are a foot high, 
with widely spreading or decumbent branches; the leaves deeply sinuate-pinnatifid or 
incised ; the lobes mostly triangular or lanceolate, acute. The calyx is merely canescent, 
or sprinkled with a few hirsute hairs. The capsules are longer and more slender than in 
any allied species (an inch long, quadrangular, Nuiét.), frequently an inch and a half or 
even two inches in length and of the same diameter (one line) throughout, truncate, pris- 
matic, porrected, or at length decurved or contorted. Seeds oblong, smooth, small. 
224, CE. PINNATIFIDA, var. INTEGRIFOLIA, Santa Fé, and along the Cimarron, in 
gravelly soil or sand; June to August. — The leaves are oblong or lanceolate, often con- 
spicuously mucronate, repand-denticulate, or with here and there a distinct salient tooth, 
both sides more or less canescent with a minute appressed pubescence. The flowers, 
and the elongated, slender, prismatic capsules, are just as in no. 223; of which it is no 
doubt a variety, and to which it sustains the same relation that CE. humifusa, Nutt., and 
(2. minima, Pursh, do to (. sinuata (Torr. & Gray, Fl. 1. p. 494). Precisely the same 
form was gathered on the Platte in Fremont’s first expedition; and on one specimen [| 
notice that the petals, instead of turning uniformly reddish or in blotches with age or in 
drying, are minutely punctate with red dots. While some forms gathered in Fremont’s 
third expedition pass by their foliage directly into the ordinary (E. pinnatifida (although, 
indeed, they sometimes exhibit running or horizontal roots), others, with narrower leaves, 
appear to run into CE. albicaulis, Nutt. ; and still others, becoming nearly or quite gla- 
brous and smooth, make a perfect transition into (&. pallida, Lindl., the narrow-leaved 
forms of which I cannot distinguish from (E. albicaulis.

margin of a low, swampy place; Sept. — Plant a span high, with the foliage and some- 
what the aspect of a Gaura; the leaves minutely strigose-canescent, half an inch long, 
oblong-lanceolate or linear, entire or obscurely toothed. The wiry stems are very leafy to 
the top. Calyx-tube slender, three fourths of an inch long, purplish, thrice the length of 
the ovoid canescent ovary, less than twice the length of the calyx-tube. Petals broadly 
obovate, entire, two thirds of an inch long, white, with some of each flower conspicu- 
ously spotted or blotched with rose-purple. Anthers linear. Divisions of the stigma 
linear, slender. Capsule sessile, canescent, one fourth of an inch long, and almost as
