with five subequal deltoideo-subulate adpressed teeth. Corolla of nearly 

 uniform red, and becoming livid in fading, very handsome, but the whole 

 raceme is less so than it otherwise would be, in consequence of the gra- 

 dual elongation of the pedicels, being disproportionately greater than the 

 rachis, by which the whole forms a dense and contused ovate mass. 

 "Vexillum ovato-acuminate, reflected from near its base, slightly striped 

 with white near its centre, somewhat callous at the claw. Alse about half 

 as long, narrow, oblongo-sickle-shaped, with a callous colourless curved 

 claw, and a tooth on its upper edge of nearly similar texture, but shorter. 

 Carina as long as the vexillum, nearly colourless on its inside in the 

 lower half, monopetalous, with colourless undivided claw, and short blunt 

 tooth on the edge on each side, acuminate, curved forwards. Stamens 10, 

 diadelphous, filament colourless; anthers uniform, oblong, yellow; pollen 

 granules minute, golden coloured, shining, round. Pistil green, as long as 

 the keel, and closely wrapped up in it ; germen glabrous, furrowed along 

 its upper edge ; style covered with long simple white hairs in a line along 

 its upper side, and extending nearly to its middle ; stigma small, termi- 

 nal, capitate. Ovules numerous, crowded. " The flowers are succeed- 

 ed by brownish-black pods, 2| inches long, seated on a slender stipe, and 

 convex on the upper instead of the lower edge ; so that unless attention 

 be given to the manner of growth, it would seem as if the seeds grew to 

 the lower instead of the upper edge. They are covered all over with a 

 delicate cottony down, in which lie the small kidney-shaped seeds, of a 

 dull yellowish-ochre colour, mottled with small dark brown blotches and 

 speckles." Hort. Trans. 1. c. 



We received at the Botanic Garden, Edinburgh, this very handsome plant 

 from Mr Low of Clapton-nursery in 1835. It has been cultivated both 

 in the open ground and in the greenhouse. In the former it lives, but 

 unfortunately does not thrive, and will never be ornamental, unless per- 

 haps on a good wall, and well protected in winter. In the latter situa- 

 tion it is most luxuriant, but has produced no fruit. It flowered first in 

 February 1837, and will probably produce a long succession of blossoms.

DESCRIPTION. Boot annual. Stem (3 feet high) herbaceous, erect, round, 

 unequally dichotomous, slightly reddened, densely covered with soft 

 glandular pubescence of unequal length. Leaves (9 inches long, 4 broad) 

 petiolate, ovate, obscurely sinuate, very unequal at the base, one or two 

 of the lower ones only, and those on the young plant, being generally 

 equal, subacute, glanduloso-pubescent on both sides, bright green above, 

 paler below, strongly veined, the veins prominent behind ; petioles 

 round, with a groove above, half as long as the leaves. Flowers in the 

 clefts of the stem, erect, peduncled ; peduncle (1 inch long) round, stout, 

 erect, becoming cernuous as soon as the flower fades. Calyx (3 inches 

 long) preen, covered with pubescence similar to that on the leaves, 5- 

 toothed, the teeth unequal, acute. Corolla twice as long as the calyx, 

 funnel-shaped, with minute glandular pubescence, white in the upper 

 half, green in the lower, plicate ; tube strongly ribbed ; limb erect, 5- 

 lobed, lobes subacute, at the bottom of each of the shallow sinuses be- 

 tween the lobes a rib is projected in form of a tooth, green, and hooked 

 inwards. Stamens as long as the tube ; filaments adherent to about two- 

 thirds of the tube, glabrous ; anthers erect, white; pollen cream-coloured, 

 granules minute, spherical. Pistil shorter than the stamens, colourless ^
