a line in diameter, tipped with a slender persistent style. — M^jagnm pam'culatum, L. Spec, 

 ii. G41.— Winnipeg Valley, Boiirc/eau (1858), and more or less establislied alons^ the track 

 of the Canadian Pacific Hailway, at Caimiove, Macoun (188;')), also coll. on balhist, Jersey 

 City, Jud</e Brown; fl. through the summer. (Adv. from Eu.) 



19. CAKILE, Tourii. Sea Rocket. (Name of doubtful perhaps Arabic 

 origin.) — Fleshy maritime amnials, generically readily recognized by their char- 

 acteristic fruit. Flowers purplish or white. Leaves more or less siuuate-toothed 

 or incised.— Inst. Suppl. 49, t. 483; Ga^rtu. Fruct. ii. 287; Beuth. & Hook. 

 Gen. i. 9'J. [By B. L. Robinson.] 



C. maritima, Scop. Leaves either narrow, linear or nearly so and suhentire, or more 

 'often \ory ilcei)ly sinuate pinnatifiil, with narrow rhachis and segments: uj.per cell of the 

 fruit considerably exceeding the lower, lanceolate in outline or ensiform, sligiitly 4-angled 

 and narrowed to an acutish point ; the lower cell often but not always appendaged at the 

 summit with two spreading teeth. — Fl. Carn. cd. 2, no. 844; DC Syst. ii. 428.— The 

 typical form of this species occurs as a hallast-weed upon the Atlantic Coast of the Middle 

 States, Brown, Parker, and a form unsatisfactorily separable by its usually more slender 

 and elongated spindle-shaped pods is indigenous in Florida, Indian Kiver, Palmer, Marquesas 

 Keys, Curtlss, Key West, Binney. This form, the var. .uquAlis, Chapm. Fl. 31, is not 

 exactly the C. cequaUs, L'Her. of the West Indies, which has more entire apparently thinner 

 leaves and still more slender almo.st linear fruit. 



Var. Cubensis, Chapm. " Stem and branches erect ; leaves linear, obtuse, dentate- 

 serrate, tapering into a petiole ; loment obovate." — Fl. ed. 2, 606. — " Keys of South 

 Florida." Not seen, but from the descri])tion of the fruit apparently different from C. 

 Americana, var. Cubensis, DC. 



Var. geniculata, Kobinson, n. var. Foliage of the typo : axes of the racemes very 

 stout and strongly geniculate : fruit fully inch in length ; both cells with several prominent 

 ribs; the upper cell elongated, oblong, scarcely acute.— C. maritima. var. af/milis, Coulter, 

 Contrib. U. S. Nat. Herb. i. 31, & ii. 22, not Chapm. — Gulf Coast, Texas, Bcrlandier, no. 

 3103, Galveston, Lindheimer, May, 1843. 



C. Americana, Ndtt. Leaves oblanceolate or obovate, shallowly sinnate-toothed or cre- 

 *nate: upper segments of fruit ovate in outline, 4-angled near the base, acuminately narrowed 

 to a compressed truncate often retuse tip.— Gen. ii. 62 ; Gray. Gen. 111. i. 170, t. 74 ; Greene, 

 Bot. Gaz. vii. 94 ; Wats. & Coulter in Gray, Man, ed. 6, 74 ; K. l?randegee, Zoe, ii. 340. 

 C maritima, Vursh, Fl. ii. 4-'^4. C edcntuUi, Hook. Fl. Bor.-Am. i. 59. C. maritima, var. 

 Americana, Terr. & Gray, Fl. i. 119. Bunias cdenttda, Bigel Fl. Bo.^t. 1.57.— Sea beaches 

 Gulf of St. Lawrence to Fla. ; on the Pacific in Central California (perhaps introduced), 

 Greene, and along the shores of the Great Lakes. Not always readily distinguishable from 

 the preceding s].ccies, of which it has sometimes been regarded as a variety. The difference 

 of foliage, however, is usually striking, and of geographic range noteworthy. A marked 

 form from Enterprise, Fla., Canin/, has an elongated oblong strongly ribbed pod, but the 

 upper cell has the characteristic 'flattened and retuse apex of this species, with which the 

 foKage also closely agrees. 

 20. RAPHANUS, L. Radish. ('Pac^aro?, used for /)a<^ans, radish.) — 



A genus of six to ten species, stout annuals or biennials, all natives of the Old 



"World and most of them of the Mediterranean region. — Gen. no. 539 ; DC. 



Prodr. i. 228. [By B. L. Robinson.] 



R. llAPiiANfsTRCM, L. (WiLi) IUdish, JoiNTKi) CiiAnLOCK.) Lcavos lyrately pinnatifid, 

 hirsute : petals most often light yellow or white anfl dark veined, rarely purplish : pud 

 strongly moniliform, 2-8-seedeil ; 'the more or less ribbed or corrugated segments only 1^ 

 to 2 hiies in In-eadth ; beak elongated, slender, and gradually narrowed to a point. — 

 Spec. ii. 669; Torr. & Gray, Fl. i. 120; Torr. Bot. Mex. Bound. 3.5; Wats. & Coulter, 

 I. c — A rapid growing and troublesome weed in waste and cultivated ground. (Introd. 

 from Eu.)
