BR/CSSICA (old classical name). Including Sinapis. 

 Cruciferx. Annual and biennial herbs, including cab- 

 bage and turnip, and their allies, and also the mustards. 

 Leaves various, the lower ones mostly 

 lyrate or pinnatifid: fls. yellow, mostly in 

 erect racemes: petals and stamens 4: pod 

 long and slender, compressed-cylindrical or 

 4-sided, beaked; seeds not winged, the coty- 

 ledons conduplicate (Figs. 625, 626). Nearly 

 or quite 100 species in Eu., Asia, Afr., and 

 many of them widely naturalized. The 

 brassicas possess a remarkable natural 

 tendency toward the thickening of parts 

 under cult., as of root, st., axillary buds, 

 If.-rosettes, midribs and even of fl.-clus- 

 ters. Oil is extracted from the 

 JGO^. seeds of several species, and the 

 ground mustard of commerce is 

 made from the seeds of B. nigra 

 and others. 



The brassicas are botanically 

 much confused, particularly in the 

 groups containing cultivated spe- 

 cies. The manuals probably con- 

 tain too few rather than too many 

 species of Brassica; at least, the 

 miscellaneous throwing of rutabagas, 

 turnips, rape and other plants into 

 Brassica campestrits is unnatural, and, therefore, unfor- 

 tunate. One of the best presentations of the true bras- 

 sicas is that of De Candolle's Prodromus, as long ago as 

 1824 (also in Trans. Lond. Hort. Soc., Vol. V, and in 

 Systema, 2:582-607), and the present treatment follows 

 that outline in general. Some of the forms that are here 

 kept separate as species may be derived from their 

 fellows, but the evidence of such origin is lost, and per- 

 spicuity demands that they be kept distinct in a horti- 

 cultural treatise. The taxonomic arrangement here 

 presented can be regarded as only tentative, however, 

 and new systematic studies should be made of the 

 entire group. 



The confusion into which our brassicas have fallen is 

 in some measure due to the various vernacular names in 

 the different countries. The French use the word chou 

 generically to include all forms of B. oleracea and the 

 rutabaga that is, all the blue thick-leaved brassicas; 

 while in England the rutabaga is called the Swedish 

 turnip. A tabular view of the different vernaculars may 

 be useful:

The Latin names in Brassica, particularly in the 

 oleracea-campestris group, have been so variously used 

 that it is practically impossible to place some of them 

 accurately.
