HIPPEASTRUM 



Distinct, and one of the best. Apparently not in the 

 Amer. trade, but it has been used in hybridizing.

 One of the most distinct of the genus. In the Amer. 

 trade. Sometimes called "Blue Amaryllis" and "Em- 

 press of Brazil." Plant out for late summer or fall 

 bloom, in a warm, sunny place. Keep bulb dry until 

 late spring. 



CC. Stigma markedhf 3-parted. 



12. ritilum, Herb. Bulb nearly globular, 2-3 in. in 

 diam., stoloniferous, with short neck: Ivs. 6-8, elongat- 

 ing after flowering, bright green, 1 ft. long and an inch 

 or more wide: scape as long as the Ivs., somewhat com- 

 pressed, glaucous, bearing 2-4 red fls. : perianth tube 

 % in. long, green, with a minute crown in the throat ; 

 segments oblong, acute, crimson and green keeled ; 

 stamens shorter than the perianth, the filaments red.

 B.M. 129. G.C. 111. 24:119. -The commonest species- 

 type in Amer. gardens, now cult, in many forms. It 

 seems to have entered freely into hybrids, and some of 

 the forms now passing as H. viltatum are perhaps mon- 

 grels. The double red feathery stripes on each side of 

 the more or less irregular-edged segments distinguish 

 this species from its congeners.

14. H. Jbhnsoni, Bury. Fig. 1070. Fls. deep dull red, 

 each segment with a white stripe down the keel. A very 

 profuse bloomer, and withstands much abuse. It is the 

 most popular single Amaryllid in this country, and is 

 particularly prized for window-gardens. It is the oldest 

 hybrid, having been raised by one Johnson, an English 

 watchmaker, who, in 1799, crossed U. Beginve with H. 

 vittalum.

HIPP6PHAE (Greek, horse-killing; alluding to the 

 berries, which are somewhat poisonous). Jileagnd.cece. 

 This includes the Sea Buckthorn, a hardy European 

 and mid-Asian shrub valued for its clusters of bright 

 orange-red berries about the size of a pea, which per- 

 sist all fall and winter. It also has the silvery or gray 

 foliage which makes several members of this family 

 useful in fine landscape eifeets. This f.-imiiv has only 2

 sexes by the more upright growth of the staminate and 

 the more twiggy growth of the pistillate plants. The 

 redder the berries the better for ornamental purposes. 

 The berries are somewhat poisonous, but are eaten by 

 birds. Though essentially a seashore plant, it is easily 

 cult, inland in common garden soil, and thrives even in 

 barren, sandy lands. It inhabits cool moving sands and 

 the alluvium of torrents. When grown abroad to hold 

 shifting sands it makes a straggling, stunted bush 2 ft. 

 or more high. Under favorable conditions it may be 

 grown into a tree 20 ft. high. The suckers may become 

 so numerous as to be troublesome. The numerous 

 spines which terminate the branches and the interlacihg 

 stems suggest its use for hedges. It is propagated by 

 layers, suckers, root-cuttings and seeds.

HOFFMANNIA (Georg Franz Hoffmann, 1760-1826, 

 professor of botany at Gottingen). Including Campy- 

 lobbtrys and Higginsia. BiibiAcew. About 15 tropical 

 American herbs or shrubs, with opposite or verticillate 

 Ivs. and small white, yellow or reil tis., cult, for the very 

 showy foliage. Corolla tubular, witli l i r:nely 5) oblong 

 or linear obtuse lobes; stamens 1 : rln^-llke disk about 

 the 2-3-loculed ovaryi style filiform, the sti.gma 2-lobed. 

 The Hoffmannias require warm temperature, although 

 they may be plunged in the open in the summer. Well 

 grown specimens are also adapted to the decoration of 

 window-gardens and living rooms. Propagated by cut- 

 tings. Hoffmannias are very showy foliage plants.
