Cult. The species of this genus are very proper for rock- 
work. Arabis, albida, alpina, arendsa, &c. will answer also for 
the front of flower-borders, as they flower earlier than most border 
flowers. The perennial species may be either encreased by divid- 
ing the plants at the root, by cuttings, or by seeds. The annual and 
biennial species are mostly weedy-like plants ; therefore they are 
only fit to be preserved in botanical gardens. They should be 
sown on rock-work, and allowed afterwards to scatter themselves, 
for by this means they are more likely to be preserved. 
XI. OUDNE‘YA (to the memory of Dr. Oudney, who 
found the present plant in many of the Wadeys between Tripoli 
and Mourzuk, and remarks that camels and mules eat it.) R. Br. 
in append. to Denh. and Claph. journ. p. 14. 
Lin. syst. Tetradymdmia, Siliquosa. Silique sessile, linear, 
beaked, with flat 1-nerved valves. Funicle adnate to the dissepi- 
ment. Seeds in one row. Calyx closed, bisaccate at the base. 
Filaments distinct, toothless. Stigmas connate, distinct at the 
apex. A smooth, branched sub-shrub, with quite entire sessile, 
veinless leaves, lower ones obovate, upper ones almost linear, 
and bractless terminal racemes of flowers; petals obovate veiny. 
This genus differs from 4’rabis in the form of the stigma.

poli and Mourzuk, in the Wadeys. Hésperis nitens, Viv. fl.

Cult. Should this plant be ever introduced into the gardens, 
it may be grown in pots filled with an equal quantity of sand 
and peat, and treated as other alpine plants. It may be either 
propagated by cuttings or by seeds. 
XII. MACROPO'DIUM (from paxpoc, makros, long, and 
Tove ročoc, pous podos, a foot; in allusion to the pods standing 
on long pedicels or foot-stalks.) R. Br. in hort. kew. ed. 2. vol. 
4. p. 108. D. C. syst. 2. p. 244. prod. 1. p. 149. 
Lix. Syst. Tetradynamia, Siliquòsa. Silique linear, pedi- 
cellate, with flat 1-nerved valves ; seeds orbicular, compressed, 
flat, girded by a very narrow membrane, disposed in one row in 
each cell, distant. Perennial or annual, smooth, erect, simple 
herbs ; with ovate-lanceolate, pointed, serrated or jagged leaves, 
and long terminal racemes, with almost sessile flowers, which are 
disposed in the form of a spike. 
1 M. niva'te (R. Br. in hort. kew, ed. 2. vol. 4. p. 108.) ra- 
dical leaves ovate, on long stalks, unequally serrated, cauline 
ones lanceolate, acuminated, narrowed at the base, entire ; flowers 
sessile; petals obovate. 2%.H. Native on the summits of the 
Altaian Mountains near the limits of perpetual snow. Cardamine

2 M. racinta‘tum (Hook, fl. bor. amer. p. 42.) leaves all 
stalked, jagged-pinnatifid ; flowers on pedicels ; petals narrow, 
linear. ©.H. Native of North America, common on dry rocks 
about Wallawallah, and at Priest’s rapid on the Columbia. 
Flowers white. 
Jagged-\eaved Macropodium? FI. June, July. Pl. 2 to 3 ft. 
Cult. M. nivale succeeds well in a rich light soil in the open 
border ; and cuttings will strike root freely under a hand-glass : 
notwithstanding it will sometimes thrive well in open borders, 
yet it is very apt to damp off in the winter; therefore we would 
advise a duplicate plant to be kept in a pot as an alpine or frame 
plant. M. laciniatus being an annual will only require to be 
sown in the open ground early in spring.
