OF ORNAMENTAL PERENNIALS.

A. TORTUOSUM, Bose. 
This is a native of Sicily and the south of Italy, which grows with curiously-twisted branches. The flowers 
are of a rich purple, and are larger than those of any other species of the genus. 
A. SICULUM, Lin. 
Is also a native of Sicily, introduced in 1804, with small straw-coloured flowers. There are two varieties, 
one of which has yellow flowers ; and another, the flowers of which are purple and yellow. 
There are some kinds of perennial Linarias ; but the only species which is decidedly ornamental is L. 
Dalmatica, which was first introduced as far back as 1731, but which was soon lost ; and though it was re-intro- 
duced in 1834, it seems to have again disappeared. It is a native of Persia, and requires protection in British 
'I gardens. 
GENUS III. 
MIMULUS, Lin. THE MONKEY-FLOWER. 
DIDYNAMIA ANGIOSPERMIA. 
Lin. Syst. 
Generic Character. — Calyx tubular, five-angled, five- toothed. 
Corolla ringent ; upper lip two-lobed; lower one trifid, usually bi- 
gibbous at the base ; segments all flat. Stamens four, didynamous, 
inelosed ; cells of anthers diverging or divaricate, at length sub-con- 
fluent. Stigma bilamellate. Capsule hardly furrowed, two.valved, 
with a loculicidal dehiscence ; valves entire, witli flat margins, dissepi- 
ment at length free ; placentas adnate. ( G. Don.) 
Description, &c. — Most of the species of Mimulus are herbaceous plants, with rough liairy leaves and 
square succulent stems. The leaves are opposite, and generally toothed. The flowers are solitary, and spring 
from the axils of the leaves. The name of Mimulus is said to be derived from the Latin word for monkey, and 
hence the English name of Monkey-flower.

Description, &c. — This plant has pale lilac flowers, which are remarkable for the large size of the lips, 
whence the specific name of ringens, or gaping. The leaves are narrow, and very slightly serrated. The plant 
is a hardy perennial, growing about two feet high, with an erect, though rather slender stem. Like all the kinds 
of Mimulus, it succeeds best in a moist and somewhat shady situation, with a loamy soil. It is a native of 
Virginia, whence it was introduced in 1759; but it is now seldom seen in British gardens, as we have so many 
handsomer species of the genus. 
2. — MIMULUS ALATUS, Ait. THE WINGED MIMULUS.

Description, &c. — This species has very nearly the same habit as the last, but the flowers are of a bright 
blue. It is a native of North America, whence it was first introduced in 1783. It was, however, soon lost.
