THE LADIES' FLOWER-GAftDEN 
GENUS I. 
BARBAREA, R. Br. THE HERB OF ST. BARBARA, OR WINTER CRESS. 
Lin. Syst. TETRADYNAMIA SILIQUOSA. 
Genekic Cuahacteb.— 'Silique 4-&ided, two-edged ; valves coDcave-kecled, awnless at the apex. Calyx equal at the base. Seeds disposed 
in one series. (G. Don.) 
Description, &c. — Most of the species belonging to this genus are cultivated only as affording a kind of 
winter or early spring salad ; but the double-flowered variety of B. vulgaris, which is commonly called the 
double-yellow rocket, is very ornamental. The name of Barbarea alludes to the plant being vulgarly called the 
Herb of St. Barbara. The other species possess no beauty in their flowers. 
1.— BARBAREA VULGARIS, R. Br. THE COMMON HERB OF SAINT BARBARA, 
OR YELLOW ROCKET. 
SvNoNVMEs. — Ervsimum Barbarea, Lin. ; E. Ivraefolium, Slok. 
Enoea VINOS. — Eug. Bot. t. 443 ; and o\i!fig. 2 in PI. 17. 
SpFciFic Charactkb. — Lower leaves lyrate, terminal lobe roundish ; 
upper leaves obovate, toothed, piiinatifid. Silique trigonal, linear, 
pointed with the style. (G. Don.) 
Description, &c. — The species is a bitter mucilaginous herb, common in various parts of Europe, particularly 
in Great Britain, always growing in moist waste places. There are two varieties — one a slender plant of little 
beauty, and the other the double-yellow rocket of the gardens. This variety is a very showy border plant, and 
it may be propagated either by cuttings or suckers, or by dividing the root. It should be grown in a rich and 
somewhat moist soil ; or if the soil be dry it should be frequently watered. 
GENUS II. 
ARABIS, Lin. THE WALL-CRESS. 
Lin. St/st. TETRADYNAMlJi. SILIQUOSA. 
Gknebic Character. — Silique linear, with flat 1-nerved valves. Seeds oval or orbicular, compressed, one row in each cell. 
Cotyledons flat. (G.Don.) 
Description, &c. — The plants belonging to this genus are all dwarf, with very pretty little flowers, which 
are produced in such profusion as to produce masses of colour. The species are thus exceedingly well adapted for 
planting on rockwork, and in geometric flower-gardens, where the object is for each bed to present a distinct 
mass of colour. The name Arabis is said to be derived from Arabia, the native place of some of the species ; 
but if so, it must be Arabia Petrasa, as all the plants included in the order require to be planted in dry, stony, or 
sandy soil. All the species are quite hardy, and they are all propagated by dividing the roots. 
Pedicels longer than the calyx. Silique linearly-elongated, sub-atten- 
uated, erect. 
1.— ARABIS ROSEA, Dec. THE ROSE-COLOURED ARABIS. 
Emcbavings. — Bot. Mag. t. 3246 ; and our^^. 6 in PI. 17. 
Specific Ch^ractkr. — Stem-leaves oblong, somewhat stem-clasping, 
sub-cordate, sinuately-dentate ; pubescently rough, with bnmchcd hairs. 
Description, &c. — This species has an erect stem, three or four inches high, which is quite downy. The 
leaves are oblong, deeply toothed, or scalloped, slightly clasping the stem at the base, and covered with little stars
