AN ENCYCLOPAEDIA 
OF HORTICULTURE. 
Hippeastrum—con/inwed. 
flowering in a mass about the month of April. Plenty 
of air and water may be administered in summer, taking 
care to get them thoroughly ripened by autumn, when 
the pots, with their contents,may be stored and kept in 
a moderately dry, cool house until starting time the 
following year. 
H. Ackermanni (Ackermann’s).* /l. crimson, handsome, very 
large. Stove. The parent of many of the large-flowering varieties. 
One of the kest of these is pulcherrima, which has a deep crim- 
son throat, very handsomely streaked with green, 
H. Alberti (Albert’s). A. orange-red, yellowish towards the base 
of each petal, full double, about 6in. across, Cuba, 1867. A very 
handsome variety, probably merely a double form of H. equestre. 
Stove. (I. H. 1866, 498.) 
H. ambiguum (ambiguous). fl., perianth tubulose; segments 
striated with red within ; throat softly bearded. 1. broad, strap- 
shaped, full green. h. 2ft. Lima, 1836. A very handsome plant. 
(B. M. 3542.) 
H. aulicum (courtly).* fl. large, extremely handsome; petals 
unequal, obovate, sharply acuminated, patent, striated, within of 
a rich crimson, green at the base, and above the green is a dark 
blotch of or aed «be pape rounded, glabrous, lft. to 14ft. high.

about twelve species of pretty; usually hardy, herbs or 
low shrubs, inhabitants of Europe, North Africa, and 
Western Asia. Flowers yellow, nodding, honeyed; pe- 
duncles axillary. Leaves impari-pinnate; leaflets entire, 
exstipellate. The species are of very easy culture in 
ordinary garden soil, and may be increased by division 
of the root, or by seeds. H. balearica requires green- — 
house or frame protection in winter, and thrives in a 
peat and loam soil. ; =
