E. cheirantholdes, Linn. TREACLE MUSTARD or WO.RMSEED MUSTARD. 

 Annual ; branches slender ; leaves lanceolate, almost entire j flowers 

 small, yellow ; stigma small. Along streams, N. 



E. pulchellum, Boiss. (or CHEIRANTHUS PULCHELLUS). ^ Compact 

 growing, much branched at base ; lower leaves oblong- spatulate, dentate, 

 or lyrate, upper oblong or lanceolate, sharply pectinate-dentate ; stigma

 Caucasus. 



19. SISYMBRIUM, HEDGE MUSTAKD. (An ancient Greek 

 name.) Pod either flattened or 4-sided, or the cross-section nearly 

 circular ; in the common species shortish, lance-awl-shaped, close- 

 pressed to the stem ; seeds oval, marginless. Flowers small. (Les-

 finely cut, twice-pinnatifid ; flowers minute yellowish ; pods oblong-club- 

 shaped, 4-sided on slender horizontal pedicels. Pa. and N. Y. to 111. and 

 S. W. Common W. 



S. officinale, Scop. COMMON H. () Stems branching ; leaves run- 

 cinate ; flowers very small, pale yellow, followed by awl-shaped, obscurely 

 6.-sided pods close-pressed to the axis of the narrow spike. Coarse weed 

 in waste places. Eu. 



S. Thailand, Gaud. MOUSE-EAR CRESS. (2) Leaves obovate or oblong,

* Whole plant glaucous-blue when in flower; leaves of the flower-stems 

 clasping ; flowers various. 



+- Leaves from, the first more or less fleshy throughout, and glaucous-blue 

 even when young j flowers creamy yellow. 



B. olerdcea, Linn. CABBAGE TRIBE. The original is a seacoast plant 

 of Europe, with thick and hard stem, and pretty, large, pale yellow flowers ; 

 upper ones entire, clasping the stem, not auricled at the base ; cult, as a 

 biennial the rounded, thick, and fleshy, strongly veined leaves collected 

 into a head the first year upon the summit of a short and stout stem. C A u- 

 LIFLOWER and BROCCOLI have the nourishing matter mainly concentrated 

 in short, imperfect, flower-branches collected into a flat head. KOHL-RABI 

 has the nourishing matter accumulated in the stem, which forms a turnip- 

 iike enlargement above ground, at the origin of leaves. KALE is more 

 nearly the natural state of the species, the fleshy leaves not forming a 

 head. BRUSSELS SPROUTS has numerous small heads along the stem 

 below the top leaves. 



B. Napu<s, Linn. RAPE. Leaves smooth from the first, more deeply 

 scalloped than in the last, not forming thickened parts above ground.
