630 FLOWERS OF GARDEN AND GREENHOUSE 
but where the thermometer is apt to fall far below 32° they should be 
housed before winter comes on. It is not easy to make the soil too rich 
for these plants, but equal parts of cow-manure and good loam will be 
found to suit them admirably. A little warmth early in the year will 
cause them to start growth sooner than in the ordinary course, and this 
may be easily maintained, and will give earlier flowers. After flowering, 
the plants should be turned outside, into a specially prepared bed that 
has been heavily manured. Give water freely during the summer, and 
thus allow the plants to feed and ripen; potting them again early in 
October, and replacing them in the cool greenhouse, where they should 
have a position fully exposed to the light. In repotting them, the offsets 
may be separated, if it is desired to increase the stock; but we think a 
large clump, well surrounded by leaves of all sizes, is more desirable 
than the single-stemmed specimens so common. When a clump has 
attained to large proportions, it has a very handsome appearance, and 
will furnish a number of offsets from its circumference every year. 
Slugs are sometimes very attentive to Richardias, and must be hunted 
out ; they attack the tender, rolled-up. young leaves, and entirely spoil 
them. R. africana succeeds when planted in shallow water by the side 
of a lake or stream. R. Pentlandii and R. elliotiana should be grown 
in a warm house at all times. 
Description of Richardia africana, the Arum Lily or Trumpet Lily ; 
Plate 2 leaves and flowers, natural size, but the leaves are young 
ones. The white trumpet is the spathe, the yellow column the spadix, 
shown separately and enlarged in Fig. 1, the upper and yellow portion 
covered with anthers. One of these, enlarged, is shown in Fig. 2, whilst 
one of the green ovaries from the base is figured separately at 3. 
FLAMINGO FLOWERS 
Natural Order ARomDE&. Genus Anthurium 
ANTHURIUM (Greek, anthos, a flower, and owra, a tail: in allusion to the 
form of the spadix). A genus containing about a hundred and sixty 
species of stove and greenhouse perennials, which differ from Richardia 
in the fully expanding spathe, and the perfect character of the flowers 
that densely crowd the spadix. These consist of a four-parted perianth, 
four stamens, and a two-celled ovary. The leaves are variable in form 
in different species: some entire, others with finger-like divisions ; in 
some species, too, the leaf-stalks are swollen. The plants often grow as
