Hippeastrum continued. 



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. Ackermannl (Ackermann's).* fl. crimson, handsome, very 

 large. Stove. The parent of many of the large-flowering varieties. 

 One of the best of these is pulcherrima, which has a deep crim- 

 son throat, very handsomely streaked with green. 



H. Albert! (Albert's). /. 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.

H. ambignum (ambiguous), fl., perianth tubulose; segments 

 striated with red within ; throat softly bearded. I. 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 red-purple ; scape rounded, glabrous, 1ft. to lift. high. 

 I. broadly strap-shaped, full green, not at all glaucous, closely 

 striated ; the apex rather obtuse, h. lift, to 2ft. Rio Janeiro. 

 Greenhouse. SYN. Amaryllis aulica. (B. M. 2983, 3311.) 



H. breviflorum (short-flowered), fl. scentless ; perianth white,

re several very handsome forms of this old species, including 



jor, 

 rich

large, bright orange, with green central star ; flore-pleno, 



orange, quite double ; and ignescens, bright light scarlet, with a 



white throat, which runs out in bars to the centre of the seg- 



ments. (R. G. 1874, 150.) 

 H. Johnson! (Johnson's), fl. dull red, with a white stripe down

profusely dotted all over with crimson. Peru, 1866. A splendid 



greenhouse species. (B. M. 5645.) 

 H. pratense (meadow). /. brightest scarlet, sometimes feathered 



with yellow at the base ; disposed in umbels on stems about 1ft. 



high. Chili, 1840. Nearly hardy. This is closely allied to H. 



fulgens. SYN. Amaryllis pratensis. (B. R. 1842, 35, under name of

 (. like those of H. equestre, but more glossy, and purple at their 

 base. h. 2ft. Brazil, 1821. Stove. (B. M. 2278.) 



H. sub-barbatum (slightly -bearded). "This beautiful plant, 

 from Rio Janeiro, occupies an intermediate place between H. 

 fulgidum and H. equestre major, to which last it approximates in 

 the colour and form of the limb, the shape of the star, and the 

 vestige of a beard, which is lust distinguishable at the mouth of 

 the tube." Stove. (B. M. 2475.) 



VoL II. 



Hippeastnun continued.

 slender greenhouse herbs or branching sub-shrubs, all 

 natives of South Africa. Flower-heads yellow, minute, 

 rayless, something like those of the Chamomile. Leaves 

 alternate, pinnatifid or pinnatisect, rarely entire. Hippias 

 thrive in a peat and loam compost. Propagated by cut- 

 tings, or by seeds.

 greenhouse resin-bearing tree of considerable size. It 

 thrives in sandy loam. Propagated by cuttings, inserted 

 in sand, under a hand glass.

 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

 meaning, literally, mad after horses ; referring to its effect 

 on mares). SYN. Mancinella. OED. Euphorbiacea. A 

 monotypic genus, the species being a tall, milk-bearing, 

 very poisonous tree. It thrives in a mixture of sandy 

 loam and peat. Propagated by cuttings, inserted in
