SOME MINOR GENERA 319 
A. foliosa has a creeping rhizome, from which arise the stems to a height 
of lor 2 feet. The leaves are lance-shaped, smooth; flower-heads pale 
yellow, about an inch across, in three- to seven-headed corymbs; August. 
Native of United States. A. montana, or Mountain Tobacco, is a pretty 
European alpine, with a rosette of smooth, radical leaves, oblong-lance- 
shaped, from which spring the few-leaved flowering stems, each with 
three or four yellow heads about 2 inches across; July. Introduced 
1731. From the roots and leaves a valuable tincture is prepared, much 
used externally for bruises and sprains, as well as internally in cases 
low fever and paralysis. A. scorpioides is another European species, 
introduced 1710, from 6 to 12 inches high, with broad, oval leaves and 
large yellow heads, one to three on a stem; June to September. Propa- 
gated by division of roots in spring, or sowing seeds in cold frame at 
same period. The best compost is one of loam, peat, and sand. 
Arctotis (Greek, arktos, a bear, and ous, an ear: shaggy fruit). 
A genus of South African perennial herbs, distinguished by the numer- 
ous involucral bracts, and the bristles between the florets. The principal 
species are: Arctotis acwulis, with a very short stem, and hoary, lyre- 
shaped leaves in threes. The flower-heads are yellow and red; June to 
September. Entire plant about 4 inches high. Greenhouse perennial, 
introduced 1759. A. arborescens has a branching stem, 2 feet high, 
and narrow-oblong, pinnate leaves. The flower-heads are large, the 
disk yellow, and the rays white above, pink beneath ; June to September. 
Evergreen undershrub, introduced 1815. A. grandiflora has pinnately- 
cut, saw-toothed leaves, and orange heads, the outer bracts turned bac 
and somewhat cobwebby; July. A biennial, about 18 inches high; 
introduced 1710. .A. speciosa is a stemless plant, very similar to A. 
acaulis, but more shrubby, with the upper side of the leaves smooth, 
and the outer series of bracts slender, with their edges turned back. 
Introduced in 1812. These plants all require greenhouse protection, 
except in summer, when they may be planted out in the driest and 
sunniest part of the garden. They are of easy culture as pot-plants, 
if grown in a compost of loam and leaf-mould. They are propagated 
by means of cuttings, which may be taken at any time, and inserted in 
sandy soil in a warm house. They must be kept rather dry, as there is 
a strong tendency for them to rot before rooting; for this reason they 
should not be covered with hand-light or bell-glass, but allowed plenty 
of air. 
Mutista (named in honour of Celestine Mutis, a South American 
botanist, 1732-1808). A genus of about thirty-six species of erect or
