570 FLOWERS OF GARDEN AND GREENHOUSE 
second year. Bulbs of the African varieties arrive here in September 
or October; the American and Pearl, in December. Some should be 
potted as soon as they can be obtained from the dealers; and if a 
succession is desired, others can be kept for months in a perfectly dry 
place, where the temperature will not fall below 50°, and a few potted 
at intervals up to June. By this means it is possible to have Tuberose 
flowers for decorative purposes nearly all the year round. They should 
be potted singly in 4-inch pots, or five in an 8-inch pot, in a 
compost of rich loam, two parts, and leaf-mould, one part, and placed 
in a warm greenhouse or frame. If space is limited, they may be put 
under the stage until they come into growth. As soon as the shoots 
appear the pots should be placed near the glass and kept there, for, 
being naturally inclined to grow tall, everything possible should be 
done to keep them dwarf. When they commence to flower they may 
be removed to a conservatory or other cool house, if in summer; 
or may even be placed out in a sunny border. Good flowers 
may be grown in a sheltered border in the open air in warm 
localities, if the tubers are planted in sandy soil in May. Readers 
will pardon us for reminding them that Tuberose is a word of 
three syllables—Tu-ber-ose; we frequently hear it pronounced Tube- 
rose.

KNIGHT’S STAR LILIES 
Natural Order AMARYLLIDEZ. Genus Hippeastrum 
HippeastrumM (Greek, hippeus, a knight, and astron, a star). A genus 
of about forty species (including Habranthus and Phycella) of bulbous 
plants with showy flowers, usually cultivated under the name of 
Amaryllis. These are of striking colours, large, funnel-shaped, and 
borne in a small umbel at the top of a hollow scape. The perianth is 
six-parted, the divisions irregular, for the upper one of the outer series 
is broader than the others, and the lower one of the inner series 
narrower. ‘The stamens are unequally inserted in the tube, and the style 
is three-lobed. The species are natives of the hotter portions of South 
America. Most of those in cultivation are hybrids, which are produced 
freely in this genus. The flower-scapes are usually produced a little 
earlier than the leaves.
