102 CRUCIFER^. Vesicaria. 



constricted near the base, and with a circular depression at the insertion of 

 the stipe. Seeds 4 in each cell (ovules 6-8), not margined : funiculi partly- 

 adhering. 



7. V. brcvistijla : densely and stellately pubescent; radical leaves lyrately 

 pinnatifid or toothed ; cauline ones oblong, sessile, dentate-serrate ; siUcle 

 globose, sessile, glabrous : style rather thick, one-third the length of the sili- 

 cle ; seeds margined, about 6 in each cell ; petals broadly obovate ; filaments 

 dilated at the base. 



Texas, Drummond ! — (T) Stems numerous from one root, about a foot 

 lone. Radical leaves 2-3 inches long ; cauline about three-fourths of an 

 inch in length, closely sessile and but little dilated at the base. Petals 4-5 

 lines long, with a short claw. Fdaments short, with a broad ovate dilatation 

 at the base. Sihcle about 2i lines in diameter. 



8. V. gracilis. (Hook.?): somewhat scabrous with sparse stellate hairs; 

 leaves oblong and Imear-oblong, entire or remotely denticulate ; silicle globose, 

 stipitate, shorter than the style, glabrous ; seeds 2-3 in each cell, not niar- 

 gined ; petals obovate ; filaments subulate. — Hook. hot.mag.t.MQ'i^l (in a 

 note.) 



Texas, Drummond ! — About a span high, erect ; several slender stems 

 from one root. Radical leaves petioled ; cauline sessile, narrowed at the 

 base. Silicle about a line and a half in length ; style filiform ; stigma 

 minute.— Hooker (1. c.) has noticed tAvo Texan species, without describing 

 them ; but from the appropriateness of the name, there can be little doubt 

 that the plant here described is his V. gracilis. 



9. V. ^/lor/a.- decumbent, somewhat pubescent with stellate hairs; leaves 

 elliptical, sessile, entire, or slightly repand ; silicle globose, with scarcely any 

 stipe ; style more than twice as long as the silicle ; seeds 2 in each cell, not 

 margined ; petals obovate ; filaments dilated at the base. 



Banks of Elkhorn Creek, near Frankfort, Kentucky, Short .'— (T) Stem 

 about a span long, slender. Leaves i-1 inch long, narrowed at each end. 

 Flowers bright yellow : pedicels half an inch in length. Silicles scarcely a 

 line in diameter, stellately pubescent. Seeds suspended from near the sum- 

 rait of the cell.— Easily distinguished by its small silicle and very long 

 style. 



§ 2. Silicle ovate; valves convex, rather Wg-i(Z.— Alyssoides, DC. 



9. V. alpina (Nutt. ! mss.) : " dwarf and csespitose, canescent with a 

 dense stellate pubescence ; leaves linear-spatulale, entire ; calyx equal at the 

 base, deciduous; silicle inflated below, compressed at the summit, shorter 

 than the slender style. 



" High hills of the Rocky Mountain range, toward the sources of the 

 Platte.— If Main stem short and thick, throwing up nuinerous stalks 2-4 

 inches high. Leaves nearly an inch long, and about a line in width." Nutt. 

 — Flowers in short corymbose racemes, large for the size of the plant. Petals 

 oblong-spatulate, one-half longer than the calyx. Filaments subulate, with a 

 callous enlargement at the base of each: anthers ovate. Silicles acute, 

 densely clothed with stellate hairs : septum usually with an oval hole in the 

 centre : cells 4-seeded. Seeds not margined. 



§ 3. Silicle didymous, much inflated, membranaceous.— "PhysaTia, 

 Nutt. mss. 



10. V. didymocarpa (Hook.) : canescent Avith a stellate pubescence ; ra- 

 dical leaves broadly obovate-spatulatc ; cauline ones spatulate-lanceolate,
