614 FLOWERS OF GARDEN AND GREENHOUSE 
splendour). Day Lilies. A genus of five hardy perennial herbs, natives 
of Temperate Europe and Asia, with bulbous rhizomes, sword-shaped, 
radical leaves, and showy flowers, produced in corymbs on leafless scapes. 
The six segments of the perianth are united at the base, and form a 
narrow tube in which is the free ovary. The principal species are: 
Hemerocallis flava, orange-yellow, fragrant, narrow-leaved; H. fulva, 
brownish yellow, not fragrant, broad-leaved; H. Middendorfi, golden 
yellow, broad-leaved; H. minor, yellow tinged with green, slightly 
fragrant, small, leaves very slender; H. awrantiaca, a recent introduc- 
tion, and the largest flowered of all, the flowers being 6 inches across 
and of a rich orange colour. All flower through the summer, the flowers 
lasting but a short time, but produced abundantly and in succession. 
H. flava and H. fulra were in cultivation here prior to 1596, and H. 
minor was introduced about 1759. They succeed in any garden soil, 
and should be planted in a border where they need not be disturbed ; 
they do well in the front of shrubberies. 
ALLIUM (the old Latin name for A. sativum, the Garlic). A minor 
genus only in the horticultural sense, for it includes about two hundred 
and fifty species of hardy bulbous perennials, natives of Europe, Africa, 
Extra-tropical Asia, and North America. The leaves are slender (flat 
or rounded) or lance-shaped, radical, giving forth a characteristic pungent 
odour when bruised. The flowers are in heads or umbels at the top of 
a slender scape; at first they are enclosed in a membranous spathe. 
The perianth-segments spread widely or assume a bell-shape. Among 
the principal species are: Alliwm acuminatum, deep rose, July, leaves 
very slender (North America, 1840); A. cwrulewm, intense blue with 
dark line down each segment, July, leaves triangular (Siberia, 1830); 
A. Moly, bright yellow, May, leaves broad, lance-shaped (South Europe, 
1604); A. neapolitanum, white, May, leaves strap-shaped (South Europe, 
1823); A. narecissiflorum, rosy purple, bell-shaped, July, leaves lance- 
. shaped (South-West Europe, 1817). They grow freely in most garden 
soils, and increase rapidly by means of offsets. No special directions are 
needed for their cultivation. A. neapolitanwm is a good plant for the 
conservatory when grown in pots ina frame. The flowers are fragrant. 
CamassIA (from Quamash, the name used by the North American 
Indians, by whom the bulbs are eaten). A genus of four or five species, 
with grooved slender leaves, about a foot long, and blue or white flowers 
in a loose raceme. The perianth-segments are slightly connected at the 
base, and when expanded the lowest one stands rather apart from the 
others. They are natives of North America. The principal species are:
