seeded ; seeds not margined ; filaments without teeth ; style 0; cotyledons accum- 
bent. (whitloe-grass.) 
AlysAsum. Calyx equal at the base ; petals entire; stamens mostly toothed; 
silicle orbicular, or elliptical; valves flat, or convex in the centre; seeds 2 to 4 
in each cell, compressed, sometimes membranously winged ; cotyledons accum- 
bent. (gold-of-pleasure.) 
Cameli'na. Silicle subovate, many-seeded; valves thick; cotyledons incum¬ 
bent. 
Subula'ria. Silicle entire, ovate, concave, (convex without;) stigma sub ses¬ 
sile ; seed linear, 2-plaited; cotyledons incumbent. 
Cram /a be. Silicle globose, stalked, coriaceous, 1-celled, without valves, decid¬ 
uous ; seed solitary, (sea-kale.) Ex. 
Luna'ria. Silicle entire, oval, flat compressed, pedicelled; valves equalling 
the partition, parallel, flat; calyx consists of coloured, sack-like leafets. (hon¬ 
esty, or satin-flower.) Ex. 
Isa'tis. Silicle compressed, oblong ligulate, without valves, 1-seeded; parti¬ 
tion like lattice-work, (woad.) Ex. 
Ibe'ris. Corolla irregular, the two outer petals longest; silicle many-seeded, 
emarginate. (candy-tuft.) Ex. 
Turri'tis. Calyx converging, erect; silique very long, striate, 2-euged; 
valves keeled or nerved ; seeds arranged in a double series ; cotyledons accum- 
bent. (tower mustard.) 
ORDER II. SILiaUOSA. 
Denta'ria. Silique lanceolate; valves fiat, nerveless, often opening elastical¬ 
ly ; receptacles not winged ; funicle dilated ; seeds in a single series, ovate, not 
margined ; cotyledons accumbent. (tooth-root.) 
CardamAne. Calyx leaves spreading but little ; stigma entire ; a single gland 
between each of the short stamens and the calyx; silique with truncate mar¬ 
gins, linear, long, bursting elastically with revolute valves, narrower, but equal¬ 
ling the length of the partitions; seed with a slender funicle, not margined. 
(American water-cress.) 
Ar'Abis. Glands 4, one within each leafet of the erect calyx, of the size of 
the reflexed scale; silique compressed, torulose, sub-divaricate; valves flat, 1 
nerved; seeds arranged in a single series ; cotyledons accumbent. (wall-cress.) 
CheiranAthus. Calyx closed, two of the leafets gibbous at the base ; petals 
dilated; silique, when young, with a glandular tooth each side; stigma 2-lobed; 
seed flat, sometimes margined, (stock-july flower, wall-flower.) 
Sina'pis. Calyx spreading; corolla with straight claws; glands between the 
short stamens and the pistil, and between the long stamens and the calyx ; par¬ 
tition extending beyond the valves of the silique, ensiform ; seeds in a single 
series, (mustard.) * 
Rapha'nus. Calyx closed, setose ; silique torose, terete, not opening by valves, 
1 or 2-celled; glands between the short stamens and pistil, and between the long 
stamens and the calyx, (radish.) 
BrasAsica. Calyx erect, converging; partition extending beyond the valves 
of the silique; seed globose; glands between the short stamens and pistil, and 
between the long stamens and calyx, (cabbage, turnip.) Ex. 
Barbare'a. Silique 4-edged; cotyledons accumbent; seeds in a single row ; 
calyx equal at the base, erect; shorter filaments with intermediate glands; 
cotyledons accumbent. (water-radish.)
