NATURAL HISTORY OF PLANTS. 



slightly unequal. Petals shortly unguiculate, or 0. Stamens 6, 4- 

 dymimous or 5 — 1 ; unequal. Siliqua short or more or less elongated, 

 subterete, rarely 2-dynamous ; style short rather thick ; stigmatiferous 

 apex subcapitate, simple or 2-lobed. Seeds ao, 2-seriate, very rarely 

 1 -seriate, minute turgid ; funicles short free. — Branching herbs of 

 variable habit, glabrous or pubescent with simple hairs, sometimes 

 aquatic ; leaves entire or variably lobed or pinnatisect ; flowers 1 in 

 short racemes, sometimes bracteate 2 (All regions of the World 3 ). 



4. Barbarea R. Br. 4 — Sepals erect equal, or lateral subsaccate at 

 base. Petals long-unguiculate. Stamens 6 free, 4-dynamous. 

 Glands 6, alternate ; 2 placentary longer and narrower. Siliqua 

 elongated, usually rigid, compressed ; style short thick sometimes ob- 

 conical ; apex compressed, capitate or 2-lobed ; valves carinate or 

 costate ; septum narrow hyaline. Seeds 1 -seriate oblong, not margi- 

 nate ; funicles free ; cotyledons accumbent on ascending radicle. — 

 Herbs erect ascending glabrous, 2-ennial or perennial ; stem angulate ; 

 leaves entire runcinate-lobate or sinuate-pinnatifid ; flowers 5 in some-

' Several subgenera and species have been 

 proposed, referred by various authors, some to 

 Cochlearia, some to Nasturtium, and some to new 

 genera. The three following of De Candolle 

 must be held the best, but on account of a few 

 species varying between them, they are neither 

 certain nor altogether natural : 1. Cardaminum, 

 siliqua short deelinate, petals white; 2. Brachy- 

 lobos, siliqua short decimate, petals yellow ; 3. 

 Clandestinaria, siliqua elongated erect, petals 

 very short or 0. Alyssopsis deflexa Boiss. 

 (Walp., Rep., i. 134), though differing in its uni- 

 seriate seeds, agrees exactly with Nasturtium in 

 flower and siliqu , N. officinalis has a ribbed 

 siliqua as in Barbarea. Teirapoma barbarei- 

 folia Tuecz. (in Linnaa, x. Litt., 104; — Endl., 

 Gen., n. 4883 ; — Deless., 7c. Sel., ii. t. 70; — 

 Payee, Organog., 211, 215, t. 44; — Seem., Bot. 

 Eer.,t. 2; — Walp., Rep.,\. 154), a plant re- 

 markable for its usually 4-carpellary gyna:ceuni 



and fruit, and held the prototype of a distinct 

 genus by many authors, is now better considered 

 by A. Geay and others a sport of Nasturtium 

 palustris R. Be. (See p. 183, not. 4, figs. 210- 

 213.)

 are distinguished by no technical character from 

 Cochlearia B. H., loe. cit.) Roripa Bess., Fnum. 

 Fl. Vohhyn. (ex Geen. & Godb., Fl. de Fr., i. 

 125) includes a few species between Nasturtium, 

 Sisymbrium, and Cochlearia, among which, ac- 

 cording to several authors, the most noteworthy 

 is R. ruslicana Geen. & Gode., loc. cit., which 

 is Cochlearia Armoracia L. (See p. 202, fig. 

 276, and pp. 223, not. 5, 270, not. 7.)
