THE DICTIONARY OF GARDENING, 
HELONIAS. According to the ‘Index Kewensis,” 
fonr species, natives of North America and Tropical 
Africa, are referred to this genus, which is closely allied 
to Tofieldia. Several plants formerly included hereunder 
are now referred to Chamelirium, Melanthium, 
Stenanthium, Veratrum, Xerophyllum, and Zy- 
gadenus. 
HELONIOPSIS (from Helonias, and opsis, resem- 
blance; alluding to the affinity of the genera). SYN. 
Sugerokia. OnpD. Liliacew. A small genus (four species) 
of greenhouse or hardy perennials, natives of Japan and 
Formosa. Flowers solitary or few at the tip of the scape, 
rather large, slightly nodding: perianth segments distinct 
or scarcely connate at base, oblong or narrow, sub-equal, 
snreading; stamens six; scape erect, simple. Leaves 
radical, petiolate, oblong or lanceolate, scarious-sheathed 
at base. Rhizome short, horizontal. H. japonica, the 
only species in cultivation, thrives in any fairly good 
garden soil, and may be increased by divisions in autumn. 
H, japonica (Japanese). /., perianth rose-coloured, five to six 
lines long, the segments free, narrow; stamens very shortly 
exserted; pedicels usually longer than the flowers; raceme 
short, two- to ten-flowered. April. J. oblanceolate, at the 
flowering period 3in. to 4in. long and lin. broad, brownish 
towards the tips. Japan, 1881. Wrongly called H. umbellata 
in G. C. ser. iii., vol. i., p. 711. (B. M. 6986.) 
HELOSPORA. A synonym of Timonius (which 
see). 
HELWINGIA. 
H. ruscifolia. 
HELYGIA. A synonym of Parsonsia (which see). 
HEMEROBIUS. See Lacewing Flies. 
H, rusciflora is the correct name of 
Fic. 442. FLOWER OF HEMEROCALLIS AURANTIACA MAJOR. 
HEMEROCALLIS. This genus embraces five 
species, natives of Central Europe and temperate Asia, 
Japan especially. 
These very accommodating plants should be freely used 
in the mixed borders and in the shrubbery. The flowers 
are yery useful for cutting if picked in the bud state, 
those of H. flava and H. Thunbergii being especially so. 
In moist or in dry soils the plants seem to do equally 
well, providing they are not often disturbed. They may 
be planted in either autumn or spring, at which time, 
too, they should be divided for purposes of increase. 
To those described on p. 134, Vol. II., the followimg 
should be added : 
H. aurantiaca (orange-coloured). //l. six to eight in a corymb; 
perianth bright orange-yellow, the segments above Sin. long, 
~ Leaves opposite, entire or toothed. 
Hemerocallis—continued. 
crisped ; main petite about lin. long. July. 7. six to eight 
to a stem, ensiform, 3ft. long, lin. broad, acutely keeled. Stem 
3ft. long. Habitat uncertain, but probably Japan or Eastern 
Siberia, 1890. 
H. a. major (larger). //l. bright orange, firm; perianth tube Zin. 
long, the limb 4in. long. 7. lin. to lin. broad, firm, strongly 
ribbed. Japan, 1895. (G. C. 1895, xviii., pp. 62, 71, f. 14; Gn. 1895, 
xlviii., p. 400, t. 1041.) See Fig. 442. 
H. citrina (Citron-yellow). 1. Lemon-yellow. China, 1897. This 
species differs from H. minor in having much larger flowers and 
leaves twice as broad; and from H. Dumortierii in the flowers 
being twice the size, with a longer tube and scape, and in the 
leaves being thrice as long. 
H. flavo-Middendorfii (hybrid). 7. Citron-yellow, the outer 
pean segments brick-red on the exterior. A garden hybrid 
Cee the species indicated in the name. 1897. (R. H. 1897, 
p. 247.) 
H. fulva angustifolia (narrow-leaved). /l. orange-yellow, the 
slender tubular portion of the perianth half as long as the 
segments. Japan, 1885. Syn. H. f. longituba (R. G. 1187), © 
H. f. maculata (spotted). . having a deltoid, reddish-purple 
blotch on the inside of the perianth. North-Western China, 
H. Thunbergii (Thunberg’s). A. 
sweet-scented. July. A. 14ft. Japan. 
HEMICARPURUS. A synonym of Pinellia (which 
see). 
HEMIGENIA (from hemi, half, and genea, to beget; 
in reference to the absence of the two upper stamens). 
Including Atelandra. Orp. Labiatey. A genus embracing 
about twenty-two species of greenhonse shrubs or under- 
shrnbs, all Australian; closely allied to Hemiandra. Two 
of them have been introduced, but they are probably no 
longer grown. 
HEMIGRAPHIS (from hemigraphos, half-written ; 
in allusion to the shape of the corolla). Orp. Acanthacex. 
A genus embracing about a score species of stoye or 
greenhonse, annual or perennial herbs, inhabiting the East 
Indies, the Malayan Archipelago, China, and Japan. 
Flowers rather small, solitary or rarely twin, spicate ; 
calyx deeply five-cleft or five-parted, the segments often 
more or less connate below the middle; corolla tube 
slender, shortly enlarged above, the limb of five rounded, 
spreading lobes; stamens four, didynamous, included ; 
bracts often imbricated; bracteoles minute or wanting. 
For culture of the 
species described below, see the allied genus Ruellia. 
H. colorata (coloured). 1. white; corolla narrow, six to seven 
lines long ; spikes terminal, tetragonal, pedunculate. J. cordate- 
ovate, crenate, bullate, 23in. long, 1gin. broad, tinted silvery-grey 
on the upper surface, purple beneath ; petioles l4in. long. Stem 
creeping, and, as well as the petioles, loosely hairy. India, 1885. 
Stove perennial. 
H. latebrosa (secret). The correct name of the plant described 
on p. , Vol. TIL., as Ruellia latebrosa. \ 
rich clear yellow, very 
HEMIMERIS. One or two species formerly included 
hereunder are now referred to Alonsoa. 
HEMIONITIS. Ivy-leaved Fern. Although some 
eight or nine species of Hemionitis are known and 
described, only three or four of them are usually grown ; 
these are easily-grown plants of dwarf habit. When grown 
in pots, all these singular Ferns require is a mixture of two 
arts of fibrous, soft peat, and one part of sand, or where 
the peat obtainable is of a somewhat close nature, the 
mixtnre is benefited by the addition of one part of chopped 
sphagnum. It is essential, on account of the few roots 
which they produce, that these plants shonld be kept in 
pots of comparatively small dimensions, and that the 
drainage should be perfect. All are liable to the depreda- 
tions of Aphides, which are easily destroyed by slight 
fumigations; occasionally, also, Thrips may make their 
appearance on the foliage, in which case the most efficacious 
treatment consists in a dip in a slight solution of lemon 
oil. H. cordata (Fig. 443) is one of the most distinct 
species. 
Propagation is readily effected by spores, which germinate 
freely, and also by means of the young plants that most 
kinds produce at the base and at the notches of the 
segments of the fronds, which, for that purpose, should be 
firmly laid on the surface of the soil recommended above.
