Sinapis.] CRUCiFERiE. 37 



On rocks and cliffs by the sea, rave. Fl. May, Jane. $. 



E. Med.—Yentnor? at the foot of the cliff, a single specimen, perhaps escaped 

 from cultivation. Also in Sandown bay, a single specimen at the foot of the 

 cliffs. Sparingly on the tufa-rock just below Ventnor mill, close to where the 

 water discharges itself on the beach, as previously observed by the Rev. G. E. 

 Smith. [Abundant on the crumbled chalk at the foot of Culver cliff, A. G. More, 

 Esq., Edrs.] 



W. Med. — At Brook, near the Chine, a single specimen of what could only be 

 this species neither in fruit nor flower, therefore in its first year of growth, I found 

 on the steep sea-bank as above. 



Root tapering, rising above the surface to the height of several inches as a 

 rounded, woody, scarred stem, leafy at the summit and branching into several 

 erect, herbaceous, round and smooth stalks that are again more or less branched. 

 Leaves smooth, thick, fleshy, very glaucous, those of the root and first year's shoots 

 large, lyrate or from the great development of the terminal lobe roundish, stalked, 

 waved and entire at the margin : stem.leaves alternate, undivided, erect, variable 

 in shape, oblong or oblong-lanceolate, cordate and semiaraplexicaul, quite sessile, 

 serrate- dentate, bluntish, the uppermost ones sometimes nearly entire. Flowers 

 in elongating corymbs, large, erect, bright lemon- verging upon golden-yellow. 

 Sepals nearly erect, smooth, equal, closely joined below, concave and obtuse. 

 Petals roundish, much longer than the calyx, spreading, with long tapering claws. 

 Stamens erect, very unequal, the 4 longer ones as high as the style, the 2 shorter 

 about ^ less : anthers yellow. Hypogynous glands 4 green ones on the outside of 

 each combined pair of stamens, oblong and suberect, the other 2 within the soli- 

 tary stamens at their ascending bases, roundish. Style long, cylindrical, often a 

 little inclined to one side ; stigma round, flattened, with a transverse chink or 

 furrow, hence slightly lobed. Pods erect, linear, tapering, quite smooth, a little 

 compressed and incurved, crowned by the permanent style, but without any beak 

 properly so called, though the final enlargement of the style downwards gives it 

 the appearance of having one. 



3. B. Napus, L. Wild Navew, Rape, or Coleseed. " Leaves 

 glabrous somewhat glaucous especially on the under side, lower 

 ones lyrate toothed, upper cord^to-lanceolate amplexicaul, j)ods 

 spreading."— 5r. Fl. p. 39. E. B. t. 2146. 



Common in cultivated land, amongst corn, clover, &c. and in waste ground. 

 Fl. May, June. $ ■ 



XI. SiNAPis, Linn. Mustard. 



" Pod 2-valved (with a sterile or one- or several-seeded beak). 

 Seeds in a single row. Calyx patent." — Br. Fl. 



1. S. nigra, L. Common or Black Mustard. Vect. Warlock. 

 " Pods appressed glabrous tetragonous, beak sterile short subu- 

 late, upper leaves linear-lanceolate entire glabrous." — Br. Fl. p. 

 40. E. B. t. 969. Brassica, Koch. 



On ditch-banks, waste ground, along hedges and roadsides, not unfrequently. 

 Fl. May — September. Fr. October. 0. 



E. Med. — Abundant along the beach between Ryde and Binstead. In Bm- 

 stead stone-pits. Abundant on ditch-banks in the Dover marshes and on the 

 shore a little E. of Ryde. Plentiful at Carpenters near St. Helen's. Abun- 

 dant at the foot of Shanklin chine. In Sandown bay with S. alba, sparingly. 

 Abundant on the Dover in 1841. [Bembridge, A. G. More, Esq., Edrs.] 



W. Med. — About Yarmouth and Norton, B. T. W. 



Taller and more spveafling than the next species, the herbage of a deeper 

 shining green, and floweis of a brighter yellow, with a slight delicate fragrance, 

 as remarked to me hv Dr. BcU-Saller.
