BRASSICA 



BRASSO-CATTLEYA 



ago. The Ivs. tend to form an oblong loose head, like 

 cos lettuce. Cabbage; also pajie 3582. 



AA. Whole plant green or but slightly glaucous when 

 in fl.: Ivs. on the fl.-sts. not prominently clasping: 

 fls. small and yellow. Annuals. (Sinapis or 

 Mustard.) 



B. Pod long, terete or nearly so: pedicels spreading. 

 8. japunica, Sieb. POT-HERB MUSTARD. Fig. 634. 

 Annual, self -sowing: rather numerous radical Ivs., 



oblong or oblong- 

 obovate, the margins 

 either crisped or cut 

 into many very fine 

 divisions, the petiole 

 distinct at its lower 

 end; st.-lvs. all peti- 

 oled: pod very small, 

 with a slender beak. 

 The very soft thin 

 Ivs. make excellent

 leaves used for greens. 



"greens." Long 

 known, but with no 

 designative name, in 

 old gardens in this 

 country, and some- 

 times run wild about 

 premises. Intro, in 

 1890 by John Lewis 

 Childs as California 

 pepper-grass. A very 

 worthy plant (Bull. 

 67,CornellExp.Sta.). 

 9. juncea, Coss. (Sindpis juncea, Linn.). CHINESE 

 MUSTARD. Figs. 626, 635. Rank and coarse grower, in 

 the common forms making great tufts of root-lvs. if 

 sown early: radical Ivs. usually abundant and often 

 very large, oval or pbovate in outline, the blade angled or 

 toothed, tapering into a narrow petiole, which generally 

 bears leafy appendages; lower st.-lvs. more or less 

 toothed and petiolate, the upper ones oblong or oblong- 

 lanceolate, entire and usually sessile or alternate: flow- 

 ering sts. and Ivs. more or less lightly glaucous: fls. 

 bright yellow: pod slender, of medium size, tapering 

 into a short seedless beak. Asia. This species is held 

 by Hooker and Thomson (Journ. Linn. Soc. v. 170) to 

 include a great variety of forms, as Sinapis Ixvigata, 

 Linn.; S. integrifolia, Willd.; S. ramosa, S. rugosa, S. 

 patens, S. cuneifolia, Roxbg.; S. lanceolata, DC., and 

 others. There are two types of it in cult, in our gar- 

 dens, one with the radical Ivs. somewhat sharply 

 toothed and nearly smooth below (sometimes grown as 



Brassica [or Sinafns] rugosa), the other with root-lvs. 

 obtusely toothed and spinescent on the veins below 

 (comprising Chinese mustard, Chinese broad-lcuvnl 

 mustard, and brown mustard). Linnaeus founded his 

 Sinapis juncea on a figure in Hermann's Paradisus (Her- 

 mann, Paradisus Batavus, t. 230, 1705), which repre- 

 sents a plant very like the former type mentioned above, 

 and which Hermann described as "lettuce-leaved." 



10. alba, Boiss. WILD MUSTARD. Tall: Ivs. pinna- 

 tifid and rough-hairy: pods spreading, hairy, the lower 

 part thick and few-seeded, the beak longer: seeds pale 

 brown, large. Weed, from Eu. 



11. arvensis, Kuntze (B. Sinapislrum, 

 Boiss. Sinapis arvensis, Linn. Sinapis- 

 trum aniense, Spach). CHARLOCK. Tall: 

 Ivs. strong-toothed, or sometimes nearly 

 lyrate: pods knotty, glabrous or hairy, the 

 upper third indehiscent and 2-edged, usu- 

 ally 1-seeded. Weed, from Eu. 



BB. Pod short, distinctly 4-angled: pedicels 

 arid pods oppressed. 



12. nigra, Koch. BLACK MUSTARD. Fig. 

 636. St. tall and upright, with wide-spread- 

 ing branches: Ivs. pinnatifid, somewhat 

 hairy: pods short and erect, glabrous; seeds 

 small and dark brown, pungent, supplying 

 the mustard of commerce. Cult, in Eu., but 

 a weed in this country. Commercial mus- 

 tard is the flour of the seeds of this species 

 chiefly, but the seeds of B. alba and prob- 

 ably of B. juncea are sometimes used. 



B. arfpressa, Boiss. Annual or biennial, 

 much like B. nigra but st. stiffer, Ivs. less 

 divided and plant somewhat hoary: pods 

 with a short 1-seeded beak. Occasionally 

 adventive from Eu. B. sinensis, Hort.= 

 B. chinensis. 



Many forms of Brassica have been described 

 that it is not necessary to endeavor to account for 

 here. Studies in crossing may be expected to indi- 

 cate some of the relationships. The writer has 

 found no difficulty in crossing cabbage-kale-cauli- 

 flower and others. See Lund and Kjaorskou, Land- 

 briigets. Kulturplanter No. 4; and "Morfologisk- 

 anatomisk beskrivolse af Brassica oleracea, B.
