of a pale green colour, the thickness of a finger, not hollow but 

 pilhj, angular, slightly pubescent and rugged, tinged with purple, 

 especially towards the bottom, branched alternately almost from the 

 ground: the root-leaves run down inlo a three-sided petiole an inch 

 in length: the slem-leavcs sessile, bright lightish green, pubescent on 

 both sides, waved a little about the edge, and having a few small 

 teeth near the base: they are from five to seven inches in length and 

 two inches in breadth, having a considerable midrib running the 

 Avhole length, very wide and tinged Avith purple towards the base, at 

 the back very prominent, with white nerves springing from it, and 

 curved towards the point: the flowers are produced all along the 

 stalks on axillary branches, and in a terminating spike: the leaves 

 on the former are similar to the stem-leaves, but much smaller, 

 beiiig not more than two inches long, and little more than half an 

 inch in breadth: the flowers are solitary, each being separated by a 

 leaflet or bracte, wider in proportion at the base than the proper 

 leaves, and drawn more to a point, diminishing gradually towards 

 the lop of the spike, till they become linear, scarcely half an inch in 

 length, and a line in breadth. 



It is observed that the flowers usually open between six and 

 seven o'clock in the evening, Avhence the plant is called Evening or 

 Night-Primrose: the uppermost flowers come out first in June, the 

 stalk keeping continually advancing in height, and there is a constant 

 succession of flowers till late in autumn. It is a native of North 

 America. The roots are said to be eaten in some countries in the 

 spring season. 



The second species has also a biennial root: the root-leaves are 

 numerous, broad-lanceolate, toothletled, pubescent, Avith a Avhite 

 rib, obliquely nerved: the stems usually five, springing out beloAv 

 the root-leaves, quite simple, ascending, rough-haired, green, Avith 

 long spreading white hairs: the central stem groAvs up later: the 

 stem-leaves are ovate-oblong, sessile, like the root-leaves: the flowers 

 axillary from the upper leaves, Avith the germ and calyx hairy. It is 

 remarked by Curtis, that luxuriant specimens exceed five feet in 

 height, that the flowers are uncommonly large and showy, and
