AN ENCYCLOPEDIA 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 Sin. ; 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, 9in. or more long ; two outer segments of corolla limb 

 linear, patent ; of the three inner, two are pale yellow, the third 

 pure white ; b.mina deeply cut into two segments ; filaments red. 

 October. I. broadly lanceolate, with an almost filiform point, 

 glabrous above, slightly silky beneath, h. 3ft. to 5ft. East 

 Indies, 1820. (B. M. 2969.) ' 



H. angustifolium (narrow-leaved).* fl. dull red, small, generally 

 four to a fascicle, expanding in succession ; corolla tube slender, 

 cylindric, about lin. long ; calyx same length, superior, cylindric ; 

 spikes terminal, erect, rigid, open, 6in. to 18in. long, smooth. 

 June. I. linear-lanceolate, lOin. to 14in. long, lin. to 2in. broad, 

 bifarious, sessile on their smooth sheaths, pointed, smooth on 

 both sides. Stems erect, 3ft. to 6ft. high. India, 1815. (B. M. 

 2078.) 



_i (flesh-coloured), fl. flesh-coloured, scentless ; bracts 

 ciliated, one-flowered, convolute ; calyx sub-tomentose. August. 

 1. bifarious, over 1ft. long, very slender, acuminate. A. 3ft. to 4ft. 

 East Indies, 1823. (B. M. 2637.) 



H. chrysoleucum (gold and white), fl. pure white, with a 

 bright orange-coloured blotch on the lip, very fragrant ; filaments 

 long, very deep orange. August. A. 5ft. East Indies. (B. M. 

 4516.) 



H. coronarium (garland).* fl. snow-white, sweet-scented; lip 

 nearly 2in. wide. May. A. 5ft. East Indies, 1791. (B. M. 708.) 



H. flavosum (yellow).* fl. yellow, numerous, fragrant ; corolla 

 tube slender ; lacinise linear ; lip erect, large, obcordate ; spike 

 terminal, solitary, erect, 6in. to Sin. long. July. I. lanceolate, 

 very fine-pointed, pubescent and pale beneath ; sheaths slightly 

 pubescent. A. 2ft. to 3ft. Silhet, Bengal (B. M. 2373, under 

 name of H. flavum.) 



H. flavum (yellow).* /. bright orange, large, fragrant. 

 July. I. 12in. to 14in. long. A. 3ft. Nepaul, 1822. In 

 many Cornish gardens, this handsome species has proved 

 nearly hardy. (B. M. 2039.) 



Hedycnium continued. 



in two rows. A. 3ft. to 5ft. East Indies, 1819. This very fine 

 species is nearly hardy in England, if provided with a slight win- 

 ter protection. The crowns, may, however, be lifted and stored 

 similar to those of the Dahlia or Canna. See Fig. 193. (B. B. 774.). 



H. gracile (slender), fl. white, with the filament red; calyx 

 tubular, membranous ; corolla tube fin. to jin. long ; lobes three, 

 filiform ; staminodes linear, acute ; lip linear-oblong, two-lobed ; 

 spike 5in. to 7in. long. September. I. Sin. to 9in. long, 2in. to 

 3m. broad, finely acuminate ; base acute, narrowed into a petiole 

 iin. to Jin. broad. A. 2ft. to 3ft. Sikkim-Himalaya and 

 Khasia Mountains, 1820. (B. M. 6638.) 



H. spicatum (spike-flowered), fl. yellowish; corolla-tube ex- 

 tending lin. beyond the sheath ; lip two-lobed, emareinate. 

 October. I., spathe erect, one-flowered, two-valved. A. 3ft. 

 India, 1810. (B. M. 2300.) 



HEDYOTIS CAMPANULIFLORA. See Cocco- 

 cypselum campanuliflorum. 



HEDYSARUM (Sedysaron, the Greek name used 

 by Dioscorides). OBD. Leguminosce. 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 bear, 

 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 racemes ovate, crowded. Summer. I. with three to 

 five pairs of elliptic or roundish leaflets, which are clothed with 

 pubescence beneath and on the margins. Stems diffuse. A. 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. 

 H. Mackenzii (Mackenzie's), fl. red, large, disposed in long 

 racemes. Summer. I., leaflets oblong, clothed on both surfaces 

 with hoary pubescence. North America, 1878. Plant decumbent 

 Perennial herb. (B. M. 6386.) 



H. obscurum (obscure), fl. purple, hi long spikes. Summer. 

 1. with five to nine pairs of ovate-glabrous leaflets. Stems erect. 

 A. 6m. Europe, 1640. Perennial herb. (B. M. 282.) 

 H. sibiricum (Siberian), fl. purple ; racemes long, axillary ; 

 bracts shorter than the peduncles. June and July. I. pinnate, 

 ovate-lanceolate, smooth. A. 4ft. Siberia, 1798. Perennial herb. 

 (B. M. 2213 ; B. B. 808, under name of H. alpinum.)
