smaller stamens.

minutely torulose.—Resembles the preceding.
5. G. Nuttallii: glabrous, stem erect, branching; leaves linear, rather
acute; flowers (minute) axillary, but mostly towards the extremity of the
branches; segments of the calyx as long as the petals and style, rather exceeding
the longer stamens ; the alternate stamens very short, with minute

OEnothera (Trichomeria) micrantha, Nutt.! mss., not Gayophytum micran-

above. Leaves 1-2 inches long. Capsules 8-10 lines in length, minutely
torulose, slender, subsessile, very many-seeded.
5. EULOBUS. Nutt. mss.
Tube of the calyx scarcely produced beyond the ovary ; limb 4-parted,
reflexed ; the very short campanulate base invested with a thickened disk.
Petals 4, rhombic-obovate. Stamens 8, inserted into the margin of the disk,
shorter than the petals, the alternate ones much shorter : filaments filiform :
anthers oblong, fixed below the middle, at length versatile; those of the
shorter stamens roundish and much smaller, fixed by the middle. Ovary
linear-filiform, 4-celled : style somewhat exceeding the longer stamens : stigma
rather large, capitate. Capsule linear, very long and narrow, 4-sided,
nearly sessile, straight, refracted, imperfectly 4-celled; the dissepiments very
thin and narrow, adherent to the valves. Seeds very numerous, obovate-
oblong, naked, erect.—A rather large virgately branched annual herb, with
fistulous stems. Leaves scattered; the lower ones oblong, unequally pin-
nately lobed; the upper linear, nearly sessile, few, denticulate. Flowers
(rather large) axillary along the virgate branches: petals white changing to
red, evanescent.
E . Californicus -(Nutt.! mss.)
California, Douglas ! Bushy plains near St. Diego, California, Nuttall!
April.—Stem (about 2 feet high) and branches thick, glabrous, with few
scattered: leaves. Calyx-segments lanceolate-linear; the extremely short
tube lined with an orange-red disk. Petals about half an inch long, rather
obtuse. Capsules 3 inches or more in length, very narrow, obtusely quadrangular,
strongly refracted; the valves somewhat membranaceous.—This
plant is not noticed in Hooker and Amott’s account of Douglas’s Californian
collection. It is so remarkably like some Cruciferous plant in appearance^
that we were about to describe it under the name of Turritopsis, doubting
however whether it should not rather form a subgenus of CEnothera, notwithstanding
its peculiar habit. It has been cultivated in the garden of the London
Horticultural Society.
6. CLARKIA. Pursh,fi. 1. p. 260, t. 11.
Tube of the calyx slightly prolonged beyond the ovary, infundibuliform,
and, with the 4-parted limb, deciduous. Petals 4, unguiculate, dilated,
3- lobed or entire; the claw with 2 minute teeth. Stamens 8; those opposite
the petals shorter: anthers oblong or linear, fixed near the base, revolute
