Specific Character.— Stem branched, pilose. Leaves lanceolate, obovate, 4-winged, ribbed, pilose, tapering into a pedicel at the base, 
pinnatifid, or toothed, somewhat ciliated, hardly petiolate; tube of Seeds ovate, acute, smooth, pale.— (G. Don.) 
Description, &c. —The plant is of a compact habit of growth, and it is beautiful from its large sweet-scented 
white flowers, which change to pink as they fade. Its capsules are very curious, having distinctly four wings ; 
and its leaves are also remarkable from their pinkish tinge. There are so very few annual white evening primroses, 
that this species deserves to be in every garden. It is a native of Mexico, and was first raised in the Cambridge 
Botanic Garden, from seeds sent, in 1796, to the Marchioness of Bute, by Professor Ortega, of Madrid. It is 
quite hardy, and may be sown in the open border as directed for Flos Adonis, in March or April, in which case 
it will flower in June or July. If treated as a tender annual, and raised in pots on a hotbed, in the same 
months, its flowers will be much larger and finer after it is planted out. It is a true evening primrose, its 
flowers never expanding in the sunshine, but generally opening about six o’clock in the evening, and fading 
before morning. It flowers abundantly, and will continue producing a succession of blossoms during the whole 
summer. Seeds may be had at Charlwood’s, or any seed-shop.

Specific Character. —Pubescent. Stem decumbent, white ; radi- longer than the stamens. Style filiform. Ovaries sessile, prismatic, 
cal leaves nearly entire, cauline ones pinnatifid, with linear, acute, furrowed.—( G. Do7i.) 
Description, &c.— A trailing species, with white stems and pinnatifid leaves. The flowers are large and 
white, and they are disposed in a kind of spike. It is a native of North America, on the plains of the Missouri. 
It is said to have been introduced in 1811, but we have never seen it, and do not know where seeds of it are 
to be procured. There are two other kinds of annual white evening primrose, one a native of Mexico, CEnothera 
latifolia, Moc. et Sess.; and the other CE.'Boothii, Dougl ., a native of California; but they have not yet been 
introduced.

red stems, very glaucous leaves, and bright lively yellow flowers.”— {Bot. Reg. t. 1040.) A native of Chile, from
