THE DICTIONARY OF GARDENING, 
Hyacinthus—continued. 
Varieties. Many of the older varieties, like Alba 
Maxima, Alba Superbissima, Laurens Koster, Grand 
Lilas, L'Innocence (Fig. 449), and La Grandeur, in their 
several colour sections, continue to rank with the best 
varieties at the present time. Still some very notable 
additions have be2n made since this work was originally 
published, and a selection of these will be found below :

HYBERNIA. ‘Two members of this genus— 
H. aurantiaria (Scarce Umber Moth) and H. defoliaria 
(Mottled Umber Moth)—are very destructive to orchard 
trees, including Apple, Plum, Nut, &c., as well as to 
Elm, Oak, Birch, Beech, and Hawthorn. The popular 
name of the first has been ill-bestowed, as the insect is 
common rather than scarce. The male, female, and 
caterpillar of the Searee Umber Moth are shown at 
Fig. 450.

Grease-banding, as suggested in Vol. IL., p. 161, may 
be profitably employed if the grease is renewed frequently 
through the winter and early spring. For all that, some 
of the females are sure to pass the bands and lay their 
eggs. This being so, Paris Green in the proportion of 
loz. to 20 gallons of water should be sprayed on to poison 
the food-plant. This may be done several times during 
the season—until, in fact, the fruits are half-grown. The 
first spraying may be done as soon as the caterpillars 
are seen. If the use of Paris Green be objected to, then 
quassia and soft soap solutions may be tried, though the 
former is preferable, 
HYBRIDISING, or CROSS-FERTILISING. 
The most important work in this connection to be 
chronicled is in the Orchid section, where some beautiful 
bigeneric hybrids have been raised. See Orchid Fer- 
tilisation. 
HYDNOPHYTUM (from Hydnon, the old Greek 
name used by Theophrastus for the Trnffe. and phyton, a 
plant; the tuber-like stock resembles a Truffle). Orv. 
Rubiacer, A genus embracing thirty species of very 
curious, stove, epiphytal, highly glabrous shrnbs, with a 
deformed, fleshy, tuberous, simple or lobed stock, excavated 
by ants; they are natives of the Indian Archipelago, 
tropical Australia, and the Fiji Islands. Flowers white, 
sessile, small, axillary, solitary or fascicled; corolla 
funnel- or salver-shaped, with a short or long tube. 
Drupe small, with two stones. Leaves opposite, leathery, 
obtuse. Two of the species haye been introduced. For 
culture, see the closely-allied genus Myrmecodia. 
H. Forbesii (Forbes’s). jl. tubular, axillary, very shortly 
pedicellate. July. fr. coral red, ellipsoid, crowned with the 
calyx limb, produced in October. J. sub-sessile, obovate, 
obtuse or slightly acute. Stems short, terete. Tuber prickly. 
New Guinea, 1886. (B. M. 7218.) 
H. longiflorum (long-flowered). 
axillary clusters. August. 7. opposite, 2in. to 2sin. long, 
ovate, fleshy, green. Stems proper terete; the base swollen 
and tuber-like. Fiji, 1891. (B. M. 7343.) 
HYDRANGEA. With the exception of dry, hungry 
soil, Hydrangeas grow freely in ordinary garden soil, but 
delight in one in which leaf-monld and peat form a 
good part. Perfect drainage should be secured, as they, 
especially H. Hortensia and its lovely varieties, delight 
in copious supplies of water during the growing season. 
The last-named group usually die down to the ground 
line in winter, but with the return of spring vigorous 
shoots are thrown up from the old stools. Much 
benefit is derived from a mulching or top-dressing of 
manure or leaf-mould in June, and the variety named 
H. paniculata grandiflora requires severe proning in 
order to produce large, massive panicles of flowers. The 
principal growths made the previous year should be cut 
back to within a couple or three eyes of the old wood in 
February or March, and the slender unripened shoots 
removed altogether. The last-named variety is well 
adapted for conservatory decoration in early spring, but 
it is not advisable to subject it to very hard forcing. 
To the species and yarieties described on pp. 162-3, 
Vol. II., the following should be added : 
H. altissima (very tall). j., buds conical, acute, but the 
calyptrate corolla becoming hemispheric before falling, owing 
to the rapid swelling of the ten stamens. J. 3in. to 6in. long, 
ovate-lanceolate, cordate, or narrow-lanceolate, serrated or 
entire except near the apex. A. 8ft. to 15ft. Temperate 
Himalayas. A spreading, hardy shrub. 
H. aspera (rough).* /l., barren ones white, large and numerous, 
disposed in a hairy corymb; sepals serrated or entire. 7. long- 
lanceolate, acuminate, 6in. to 8in. long, 2in. to 3in. road 
sometimes elongated to the petioles, the upper surface slightly, 
the lower densely, hairy. h. sometimes 20ft. Temperate 
Himalayas, 1889. Hardy. This somewhat resembles H. panicu- 
lata in habit. 
H. Belzonii (Belzoni’s). A form of H. Hortensia. 
H. chinensis (Chinese). 7. having the enlarged sepals almost 
fleshy, and nearly equal, remaining till the fertile flowers have 
matured ; cymes much larger. J, 3in. to Sin. long. Habit stouter. 
Otherwise closely resembling H. virens. North China. Hardy. 
H. cordata (heart-shaped). A synonym of H. arborescens. 
H. hirta (hairy). #. white, disposed in numerous terminal (not 
radiating) umbels; stigma bilobed; peduncles and petioles 
fl. tubular, jin. long, in 
hairy. /. ovate, serrated, villous, Nettle-like, becoming nearly 
glabrous with age. Branches slender, at first hairy. dh. 
Sit. to 4ft. Mountains of Japan. Hardy. 
H. Hortensia (Hortensia). The correct name of H. hortensis. 
H. H. acuminata (taper-pointed). #. blue. Syn. H. japonica 
ceerulescens. Of this there are forms with white and pink 
flowers. 
H. H. Belzonii (Belzoni’s). /., inner sterile ones deep blue; 
sterile ones white or tinged with blue, and having entire 
sepals. There is a variegated leaved form of this. 
H. H. Lindleyana (Lindley’s). #7, outer ones of the umbel 
white or bluish, irregularly spotted with red on the borders; 
central flowers small. A stout variety. Syn. H. H. roseo-alba 
(Gn. 1894, ii., p. 467, t. 990). 
H. 4H. ramulus-coccinea (having scarlet branchlets).* 
jl. tinted with rose, large; peduncles translucent red. Young 
shoots and petioles of a dark plum-red. 1890.
