AN ENCYCLOPÆDIİA -OF HORTICULTURE.

Hedychium— continued, 
Occasional supplies of liquid manure are beneficial in 
securing strength and vigour. These plants are also 
valuable for sub-tropical gardening, and for this purpose 
may be treated similar to Canna (which see). For pot 
culture, they may be placed in large pots or tubs, in 
spring, using rich soil, and applying plenty of water and 
liquid manure when established. When flowering is over, 
the spikes may be cut down. In spring, when the plants 
are repotted, the rhizomes can be divided. The second 
season, the spent earth can be partly removed, and the 
plants repotted into pots or boxes only an inch or two 
larger. Where a heated tank is used for growing tropical 
water plants, place the bottom of the pots or tubs, con- 
taining the Hedychiums, in the water to a depth of 2in. 
or 3in.; where such a convenience does not exist, water 
the plants two or three times daily during the season of 
growth. Of those now in cultivation, H. Gardnerianum 
is by far the commonest; and, with the exception of 
that species, and of H. flavum, the ones mentioned below 
are stove plants. 
H. acuminatum (taper-pointed). fl. handsome, fragrant ; spike 
loose, gin. or more long; two outer segments of corolla limb

une. Z. linear-lanceolate, 10in. to 14in. long, lin. to 2in, broad, 
bifarious, sessile on their smooth sheaths, pointed, smooth on 
aie Stems erect, 3ft. to 6ft. high. India, 1815. (B. M. 
H. carneum (flesh-coloured). M. flesh-coloured, scentless ; bracts

East Indies, 1823. (B. M. 2637.) 
H. chrysoleucum (gold and white). fl. pure white, with a 
bright orange-colored blotch on the lip, very fragrant ; filaments 
ee’) very deep orange. August. h. 5ft. East Indies. (B. M. 
H. coronarium (garland).* A. snow-white, sweet-scented ; lip 
nearly 2in. wide. May. h. 5ft. East Indies, 1791. (B. M. 708.)

very fine-pointed, pubescent and pale beneath; sheaths slightly 
pubescent. h. 2ft. to 3ft. Silhet, Bengal. (B. M. 2378, under 
name of H. flavum.) 
H. flavum (yellow).* fl. bright orange, large, fragrant. 
July. Z. 12in. to 14in. long. h. 3ft. Nepaul, 1822. In 
many Cornish gardens, this handsome species has proved 
nearly hardy. (B. M. 2039.) *

fragrant. — l. broadly lanceolate, stem-clasping,

in two rows. h. 3ft. to 5ft. East Indies, 1819. This very fine 
species is nearly hardy in England, if provided with a slight win- 
ter protection. he crowns, may, however, be lifted Hee stored 
similar to those of the Dahlia or Canna. See Fig. 193. (B. R. 774.). 
H. gracile (slender), jl. white, with the filament red; calyx

HEDYOTIS CAMPANULIFLORA. See Cocco- 
cypselum campanuliflorum. 
HEDYSARUM (Hedysaron, the Greek name used 
by Dioscorides). ORD. Leguminose. This genus includes 
about fifty species of elegant hardy perennial herbs or sub- 
shrubs, which are distributed throughout Europe, North 
Africa, and the temperate and mountainous parts of Asia, 
two species being North American. Flowers purple, 
white, yellowish-white, or rarely yellow; peduncles beare 
ing racemose spikes of large flowers. Leaves impari- 
pinnate; leaflets entire, often pellucid-dotted, exstipel- 
late. Very few species are grown in our gardens, with 
the single exception of H., coronarium. They are all of 
very easy culture in ordinary gardens, but open, sunny 
spots, and good deep soil, are most calculated to insure 
success. Increased by seeds. 
H, coronarium (garland).* French Honeysuckle. fl. deep red; 
spikes or —— ovate, crowded. Summer. /. with three to 
five pairs of elliptic or roundish leaflets, which are clothed with 
pubescence beneath and on the margins. Stems diffuse. h. 3ft. 
to 4ft, South-west Europe, 1596. Perennial herb. There is also 
a white-flowered variety. H. flexuosum, a closely allied species, 
from Southern Spain, has red flowers, tinged with blue.

—— mari l., leaflets oblong, clothed on both surfaces
