64 MTTSTARD FAMILY. 



13. CHEIRANTHTJS, WALLFLOWER. (Greek: hand, flower.") 

 Slightly, if at all, hoary ; the showy flowers orange, brown-reddish, or 

 yellow ; seeds flat. % 



C. Chelri, Linn. Common Wallflower. Stem woody, crowded with 

 the narrow and pointed, entire leaves. Cult, from S. En., not hardy N., 

 a much-prized house-plant. Double varieties are especially ornamental. 



14. BARBAREA, WINTER CRESS. (Anciently called the Herb of 

 Santa Barbara.) Seeds oval. Leaves used by some as winter salad, but 

 bitterish. (Lessons, Figs. 425, 426.) © % 



B. vulgaris, R. Br. Common W. or Yellow Rocket. Smooth, with 

 green, (sometimes variegated) lyrate leaves, and bright yellow flowers in 

 spring and summer ; pods erect, crowded in a dense raceme much thicker 

 than their pedicels. Common in old gardens and other rich soil. Cult, 

 as a salad ; leaves closely resembling taste of Water Cress. 



B. praecox, R. Br. Early W. or Scurvy Grass. Probably a variety 

 of the last, with more numerous and narrower divisions to the leaves ; the 

 less erect pods scarcely thicker than their pedicels. Cult, from Penn., S., 

 for early salad ; beginning to run wild. 



15. HESPERIS, ROCKET. (Greek : evening, the flowers being fragrant 

 then.) Pods long and slender, with a single row of marginless seeds 

 in each cell (as broad as the partition) ; flowers rather large. % 



H. matronalis, Linn. Common or Dame R. Tall and rather coarse ; 

 leaves oblong or lanceolate, toothed ; flowers in summer, followed by (2'- 

 4') long and slender pods. Gardens, from Eu., inclined to run wild in 

 rich shady soil. 



16. MALCOLMIA. (Named for W. Malcolm, an English gardener.) 

 Pods somewhat thickened at the base. Otherwise much like Hesperis. 



M. marltima, Br. Mahon Stock, called Virginia Stock in England, 

 but comes from the shores of the Mediterranean ; a garden annual not 

 much cult., a span high, with pale green, oblong, or spatulate nearly 

 entire leaves, and pretty, pink-red flowers changing to violet-purple ; also 

 a white variety (much smaller than those of true Stock) ; pods long and 

 slender. 



17. THELYPODITJM. (Greek: female, foot, the ovary in some 

 species stalked.) Flowers pink-purple, rather showy. © y. 



T. pinnatifidum, Wats, (or Arabis hesperidoIdes) . Smooth, erect, 

 l°-3° high ; with rounded or heart-shaped long-petioled root-leaves, 

 ovate-lanceolate stem-leaves (2'-6' long), the lower on a winged petiole 

 or with a pair of small lateral lobes ; petals long-clawed ; pods spreading, 

 narrow ; seeds wingless. - Banks of the Ohio and W. 



18. ERYSEMUM. (Greek : to draw blisters, from the acridity.) Seeds 

 oblong ; sepals nearly equal and alike at the base. 



* Flowers orange. 



E. asperum, DC Western Wallflower. Wild from Ohio W. & 

 S. ; like the wild state of the Wallflower, with bright orange-yellow 

 flowers, but the seeds are different, and the (3'-4') long pods quite square 

 in the cross-section ; the leaves somewhat toothed and hoary. © %
