20G TETRADYNAMIA— SILIQUOSA. Matthiola. 



leathery ; rounded at the extremity j each tapering at the base 

 into a short footstalk. Fl. corymbose, large, light purple, fra- 

 grant, often double ; their claws pale and greenish. Pod 2 or 

 2i inches long, crowned with the sessile stigma subtended at 

 each side by a small point; the valves frequently dissimilar, one 

 being more keeled than the other. Seeds most convex at one 

 side, light brown, surrounded entirely by a white filmy border j 

 cotyledons accumbent, as may be seen without taking off the 

 skin. 

 I believe this species is naturally perennial ; though in gardens, 

 remote from the sea, it is seldom more than biennial, and in- 

 deed often perishes the first winter, without flowering.

Biennial. August. 



Root long and tapering. Whole he7-b clothed with densely intri- 

 cate starry down, intermixed with short glandular rigid prickles, 

 which abound most on the pods. Stem branched, widely spread- 

 ing, 2 feet high, round, leafy. Lower leaves most sinuated; 

 upper undivided and entire. FL the size of the foregoing, but 

 of a more dingy hue j not fragrant by day, but in the evening 

 very highly scented, with a kind of aromatic pungency, render- 

 ing this species well worthy of a place in gardens. Stigma ses- 

 sile, bluntly protuberant at each side. Pods 3 or 4 inches long, 

 convex at each side, all over hoary and glandular. Seeds with 

 a membranous border. The taste of the whole herb is alkaline 

 and bitterish. Petiver has by mistake copied, for this, the ex- 

 cellent wooden cut of Matthiola tricuspidata , Cheiranthus tricus~ 

 pidatus of Linnaeus, published in the Hortus Medicus of Came- 

 rarius,/. 24. His error might perhaps mislead Mr. Hudson in 

 the first edition of FL Anglica,
