VII, CRUCIA‘CER: VE/LLA. 53 
spiny-toothed, Racemes diffuse. Root creeping. Filaments bidentate. 
(Don’s Mill.) An evergreen undershrub, West coast of N. America, on 
the Rocky Mountains. Height 1 ft. to 2 ft. Introduced in 1822. Flowers 
yellow; April and May. Berries purplish black; ripe in September. 
Fariety. : 
a M.r. 2 répens-fascicularis, — Habit of M. fascicularis, with larger and 
more robust foliage, resembling that of M.répens. A sport, or a 
hybrid, produced accidentally in the Sawbridgeworth Nursery. 
The shoots consist chiefly of short unbranched suckers, with the leaves some- 
what glaucous on both surfaces. The racemes of flowers are terminal, nume- 
rous, fascicled, diffuse, rising from scaly buds. The plant, in British gardens, is 
perfectly hardy, and produces a profusion of rich yellow flowers in April 
and May. Layers or suckers; but it does not root readily. Seeds are 
sometimes produced. 
Other Species of Afahénia are no doubt in British gardens; but as they 
have been only raised lately from Nepal or Mexican seeds, nothing can be 
recorded of them with that degree of certainty and detail which is suit- 
able for this work. Jahonia tenuifolia, a Mexican species with pinnate 
leaves, and entire quite smooth leaflets, on very long slender footstalks, has 
been raised in the Horticultural Society’s Garden, and may probably be as 
hardy as M. fascicularis ; but this is uncertain. JZ. nepalénsis, M. acanthi- 
folia, M. tragacanthotdes, and M. caraganzfolia, are said to be very desirable 
species. 
Section II. 
Carpella solitary, or connate ; Placenta parietal (that Part of the Capsule which 
the Seeds are attached to adhering to the Sides or Walls of the Ovary or Ger- 
men), attached to the Walls or Cells of the Ovary. 
Orper VII. CRUCIA'CE/. 
Onp. Cuar. The order Crucidicez is readily recognised by the cruciform 
arrangement of the petals, which are always four, in conjunction with tetra- 
dynamous stamens, and the fruit a silique or silicle. — Though there are 
several species which, technically considered, are ligneous plants, such as 
Aljssum saxatile, J béris sempervirens, Cheiranthus Cherri, and some others 3 
yet, in a popular point of view, the only shrub included in the order is the 
Vélla Pseido-C¥tisus. 
Genus I. 
J 
VE/LLA L. Tue Vetta. Lin, Syst. Tetradynamia Siliculésa. 
Derivation. The word Vélla is Latinised from the word velar, the Celtic name of the cress. . 
Gen. Char. Stamens the 4 longer in 2 pairs, the 2 of each pair grown together. 
Style ovate, flat, tongue-shaped, at the tip of the silicle. Silicle ovate, com- 
pressed, its valves concave. Partition elliptic. Cotyledons folded, the embryo 
root disposed in the sinus of the fold. (Dee. Syst.) ; 
Leaves simple, alternate, exstipulate, sub-evergreen ; toothed or serrated, 
glaucous. Flowers in axillary spikes, yellow, seldom succeeded by seed pods 
in the climate of London.—Shrub low, suffruticose, native of Spain,
