 prostrate, 2-7 dm. long, the branches spreading : leaves 2-10 cm. long ; blades oblong or 

 oblanceolate, obtuse, undulate or sometimes coarsely-toothed, mostly longer than the 

 petioles : pedicels ascending or spreading, rather stout, 4-6 mm. long : sepals narrowly 

 oblong, 3.5-4 mm. long : petals pale purple ; blades cuneate-obovate : pods 1.5-2 cm. long ; 

 lower joint enlarged upward, sometimes globular, nearly terete ; upper joint fusiform-lan- 

 ceolate, acuminate and acute, 6-ridged, ^ longer than the lower one. [(7. maritima var. 

 aequalvs Chapm., not L'Her.]

7. Cakile Cubensis Kunth. Relatively slender. Stem widely branched : leaves few ;

 obconic to turbinate : upper joint conic or ovoid-conic, mostly over 1 cm. long, 10-ridged, 

 not constricted at the base. 



In sand, Florida Keys. Also in the West Indies and Central America. 



8. Cakile Cakile ( L. ) Karst. Stem spreading : leaves with pinnatifid blades, the 

 segments linear : pods about 2 cm. long, lower joint dilated at the top, flattened ; upper 

 joint mitre-like, about 1.5 cm. long, constricted near the base, with broad ridges and a 

 slender beak. 



About seaports, New Jersey and North Carolina. Adventive from Europe. 



18. KONIGA Adans. 



Annual or perennial caulescent herbs or shrubs, the foliage pubescent with branched 

 hairs. Stems erect or decumbent. Leaves alternate : blades entire, narrow. Flowers per- 

 fect, in racemes or panicles. Sepals 4. Corolla white : petals 4, entire, with claws, sur- 

 passing the sepals. Stamens 5 : filaments with two small glands at the base. Ovary sessile :
