it is larger in all its parts. Radical leaves lyrate, emulating 

 those of Doronicum plantagineum. 



Plantain-leaved Winter-Cress. Fl. May, Aug. Clt. 1799. 

 PI. 1 to 2 feet. 



7 B. INTEGRIFOLIA (D. C. syst. 2. p. 208.) radical leaves en- 

 tire, oblong, stalked ; stem ones auriculately-stem-clasping. 

 If.. H. Native of Cappadocia. Pods unknown, but from the 

 habit of the plant it appears to be related to Barbarea. 



Entire-leaved Winter-Cress. PI. foot. 



Cult. None of these plants are worth cultivating for orna- 

 ment, except the double flowering variety of Barbarea vulgdris, 

 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. 

 pro? 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.

Far. /3, A'rabis incarnata, Pall, in herb. Lamb. Differs 

 from the species in having longer leaves, which are nearly an

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.

 rian nobleman and botanist.) Sternb. et Hopp. diss. with a figure.

LIN. SYST. Tetradynamia, Siliquosa. Silique oblong, some- 

 what cylindrical ; with flattish valves and a sessile stigma.

 the habit of A'rabis ccerulea, villous with branched down. 

 Leaves linear smooth ; radical ones crowded, stem ones few. 

 Racemes terminal, at first corymbose, afterwards lengthening 

 out. Pedicels shorter than the calyx. Flowers purplish. 



1 B. ALP!NA (Sternb. et. Hopp. 1. c.) leaves spatulately-linear, 

 entire ; fructiferous, racemes short. I/ . H. Native of Upper 



Carinthia and Salisburgh, in the Alps. Deless. icon. sel. 2.

 racemes loose, elongated. Tf.. H. Native of Copper moun- 

 tains, from Point Lake to the Arctic Sea. Stems erect, ribbed. 

 Pods torulose. 



Smooth Braya. Fl. April, June. PI. 3 inches. 



3 B. PILOSA (Hook, fl.bor. amer. t. 17. f. A.) stem woody at 

 the base ; leaves lanceolate, pilose rosulate, entire ; scapes 

 naked ; racemes crowded many-flowered, at length elongated ; 

 stigma slightly 2-lobed. I/ . 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. PI. 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\
