7 B. wreertirozia (D. C. syst. 2. p. 208.) radical leaves en- 
tire, oblong, stalked; stem ones auriculately-stem-clasping. 
u.H. Native of Cappadocia. Pods unknown, but from the 
habit of the plant it appears to be related to Barbaréa. 
Entire-leaved Winter-Cress. P1. 4 foot. 
Cult. None of these plants are worth cultivating for orna- 
ment, except the double flowering variety of Barbaréa vulgaris, 
commonly called Double-yellow Rocket, which is certainly a very 
ornamental plant for flower borders; this may be increased by 
cuttings, suckers, or dividing the plants at the root. The B. 
pre‘cox is cultivated in gardens as a spring salad, and this as 
well as the rest of the species are easily increased by seed, or di- 
viding the plants at the root. They thrive best in a damp or 
moist situation, in any kind of soil.

Var. B, A’rabis incarnata, Pall. in herb. Lamb. Differs

Wall-flower-like Stevenia. Fl. Jun. Aug. Clt. 1823. Pl. 4 ft. 
Cult. The species of this genus answer well for ornament- 
ing rock-work, where the seeds should be sown in the spring, 
but not sooner than the end of March.

naked; racemes crowded many-flowered, at length elongated ; 
stigma slightly 2-lobed. 2%. H. Native of North America, 
perhaps on the Rocky Mountains. Every part of the plant ap- 
pears to be more or less pilose. A beautiful tufted plant. 
Pilose Braya. Fl. April, June. Pl. 3 foot. 
Cult. The species of this genus are pretty little alpine plants ; 
they should be kept in pots of a small size, which should be well 
drained with potsherds, and treated as other alpine plants. The 
mould which answers them best, is an equal mixture of sand, 
loam, and peat. They may be increased by dividing the plants 
at the root, or by seeds. If they would stand the winter unshel- 
tered, they would be a desirable addition to rock-plants.

disposition of the foliage on the stems, which gives to them 
a pyramidal form; from the same reason the plants are called

than the calyx. &. H. Native throughout Europe in dry ex- 
posed situations: in Britain, on banks by road sides, in a dry 
gravelly soil, rare in Scotland; also of North America, from 
Hudson’s Bay to the Rocky Mountains, and as far north as lat. 64°.
