TETRADYNAMIA— SILIQUOSA. Raphanus. 225 



Common throughout the isle of Thanet, particularly about Rams- 

 gate. Mr. Dillwyn. Below Bristol. Mr. E. Forner. 

 Annual. August, September. 



Root tapering, small. Stem branching from the bottom, about a 

 span high, spreading, leafy in the lower part, clothed all over 

 with reflexed bristly hairs. Leaves usually quite smooth, of a 

 lightish green, not glaucous, varying much in form, either 

 broadly lanceolate inclining to obovate, or imperfectly lyrate ; 

 deeply serrated, or unequally sinuated 3 always acute, not 

 rounded, at the extremity, and tapering at the base into afoot- 

 stalk. Ft. lemon-coloured, smaller and paler than the last, in 

 dense abrupt corymbose clusters, greatly elongated after flower- 

 ing. Cal. moderately spreading from the bottom, a little hairy. 

 Pet. obovate, somewhat spreading. Pods on distant spreading 

 stalks of various lengths, much like those of S. tenuifolia, but 

 less decidedly erect, and the seer/s less accurately double-ranked. 

 Style and stigma as in that species. The calyx in both spreads 

 less than the character of a Sinapis requires. I have Gouan's 

 plant from himself. It is not constant enough in the deeper di- 

 visions of its leaves to be marked as a variety.

Cal. erect ; leaves oblong, parallel, converging, deciduous ; 

 2 of them slightly prominent at the base. Pet. obovate, 

 or inversely heart-shaped, spreading; claws linear, erect. 

 Filam. awl-shaped, simple, erect. Anth. oblong, a little 

 spreading. Glands^; 2 at the inside of the shorter fila- 

 ments ; 2 at the outside of the longer. Germ, cylindrical, 

 tapering. Style awl-shaped. Stigma capitate, small, en- 

 tire. Pod oblong, imperfectly cylindrical, tapering up- 

 ward, irregularly tumid, as if more or less jointed, coria- 

 ceous, not bursthig, of 2 incomplete cells, the membra- 

 nous partition often obliterated. Seeds pendulous, glo- 

 bose, forming a single row ; cotyledons folded, incum- 

 bent, their doubled edges meeting the radicle. 



Upright, branched, s})rea(ling, smooth or bristly herbs; 

 their lower leaves lyrate. FL large, yellow, white, or 

 pur})lisli, often veiny. Pods internally spongy, very va- 

 riable as to their jointed ap})earance, in the same species ; 

 so that even Prof. DeCandolle preserves the Linna?au 

 genus entire, in opjwsition to the opinion of Tournefbrt 

 and Gaertner, who founded their i^ewws Rapharii strum on 

 the more decidedly jointed pods^ breaking transversely,
