opposite, remarkably saccate at the base, the other two 
opposite ones are exceedingly narrow, especially at the 
base, and not in the least saccate; all of them purplish- 
green. Petals equal, the limb obovate, obtuse, or retuse, 
pale purple, beautifully and delicately veined, deep purple 
at the base; the claw long, linear, slender, pale. Sta- 
mens scarcely longer than the calyx: four longer ones with 
broader filaments. Anthers oblong, broader at the base, 
yellow. Pistil shorter than the stamens. Fruit: a siliqua, 
three to five inches long, slender, tetragonal, the angles 
ribbed, with rather a long beak, and a small, emarginate 
stigma. Seeds small, in two rows, oblongo-obovate, pale 
brown, scarcely winged or margined. Cotyledons folded, 
so as to represent when cut through transversely the letter 
V; and to the face of the inner one the radicle is applied. 
The Glasgow Botanic Garden is indebted for the posses- 
sion of this plant to Messrs. Youne of Epsom, whose choice 
collection of plants is only equalled by the liberality with 
_ which they distribute them wherever they can be of real 
service to Science, and who may justly be ranked among 
the first and most zealous cultivators in the kingdom. 
Although introduced, as we learn from the Hort. Kew., 
ever since the year 1739, to Great Britain, it yet exists, 
we believe, in no collections, but those which derived it 
from the Messrs. Youne; though few plants are more 
worthy of cultivation. 
The colour and size of the flowers are remarkable in this 
tribe. In England it has been treated, though a native of 
Barbary, Greece, and the Levant, as a hardy annual. In 
our less genial climate, we have hitherto given it protection 
in the greenhouse, where it has flowered in March a 
April.
