THE DICTIONARY OF GARDENING, 
Hypoderris—continued. 
these Ferns are well adapted for the decoration of the 
warm rockery, where their foliage, of a massive nature, 
forms a crane contrast to that of plants with more 
finely-divided fronds. H. Brownii (Fig. 458) is an un- 
common and distinct species. 
HYPOGENOUS. Growing upon the under-surface of 
anything. (Not to be confounded with Hypogynous.) 
HYPOLEPIS. All the species of 2a ea og require 
either stove or greenhouse temperature. ney: are highly 
ornamental when planted in the rockery, for which purpose 
they are most aseful, as they thrive best when associated 
with stones, over and amongst which their creeping rhizomes 
delight to run, although they do not cling to the stones. 
All are of easy culture, and when kept in pots should be 
grown in rough peat with a good sprinkling of small stones 
and silver-sand, as they require an abundant supply of 
water at the roots at all times of the year. that 
account also it is indispensable that the drainage of either 
the pots or the part of the rockery in which they are 
planted should be perfect, any deficiency in this respect 
producing most disastrous results. Hypolepises should be 
grown in a fairly shaded position, as the rays of the sun are 
hurtful to their foliage, which in most instances is of a 
soft, papery texture. All the species may be propagated 
from spores, which in most cases vegetate freely ; but they 
are usually increased by the division of their rhizomes, this 
being a quicker and less troublesome mode of repro- 
duction. H. repens produces spores so freely that when 
once obtained it becomes a troublesome weed, covering 
every Fern-pan, to the exclusion of less robust kinds. 
H. Bergiana is singularly prolific, and the way in which 
it reproduces itself most readily is very peculiar, and 
confined to this species: from its tiny fibrous roots spring 
a quantity of small, seedling-like plants, which form 
pooleaiaed subjects much more quickly than seedlings 
proper. 
To the species described on p. 
following should be added : 
H. amaurorachis (having a dark rachis).*

fronds handsome, very hairy, elongated-triangular, 3ft. long, 
2ft. broad at base; pinne distinctly stalked, those at the base 
opposite, the others alternate; pinnules undulated and notched. 
sori abundant and conspicuous, solitary in the notches of the

H. anthriscifolia (Anthriscus-leayed), of Presl. rhiz. stout,

deeply-pinnatifid divisions. sort two to four together in the

Hypolepis—continued. 
H. anthriscifolia (of gardens). This hardy plant is quite dis- 
tinct from the previous species. rhiz. small, wiry. sti. slender, 
short, aia hairy. fronds quadripinnatifid, resembling 
those of the Lace Fern (Cheilanthes elegans), 6in. to Tin. long, 
2hin. to 3in. broad. Syns. Cheilanthes anthriscifolia and 
Microlepia anthriscifolia (of gardens). 
H. millefolia (Milfoil-like). rhiz. stout, wide-creeping. sti. 
erect, about 6in. long, ies brown. fronds broadly triangular, 
lft. or more in length, 4in. to 6in, broad, stalked, slightly hairy 
below; pinnz having their stalks slightly winged; ultimate 
segments sharply toothed. sori placed in the lower sinuses 
only. New Zealand. Greenhouse. 
H. radiata (rayed). A garden name for Cheilanthes radiata. 
So IE (remarkable). A synonym of Cheilanthes chloro- 
phytta, 
HYPOLYTRUM. Syns. Albikia, Beera, Hypzx- 
lyptum (in part), Hypelytrwm, Tunga. Spikes panicled, 
the branches rigid; bracts long and leaf-like. Leaves flat, 
somewhat thin, three-nerved, gradually narrowed to each 
end. Stem with some nodes far above the base. To the 
species described on p. 170, Vol. II., the following should 
be added : 
H. Schraderianum (Schrader’s). J. tufted, 24ft long, 2in. 
broad, entire, green with purple margins. Brazil, 1893. A 
stout, Grass-like plant. (I. H. 1895, p. 25, f. 5.) 
HYPONOMEUTA PADELLA (Small Ermine 
Moth). This insect, described and illustrated under 
Hawthorn Caterpillars, is a great pest to the Apple- 
grower; it is also found upon the Blackthorn, but so far 
it does not appear to have been destructive to cultivated 
Plums, though it is, nevertheless, a most undesirable 
orchard visitor. Feeding, as the larve do, in a common 
web, they should be readily destroyed by holding 
underneath the nest a pail containing boiling water, into 
which the cut-out colony should be thrown. 
HYPOPHYLLANTHUS LINDENI. This is the 
correct name of LErythrochiton Hypophyllanthus, which 
is now classed as a distinct, monotypic genus. 
HYPOTHRONIA. A synonym of Hyptis (whic 
see). 2 
HYPOXIS. Of this genus fifty-one species have been 
enumerated ; they are found in tropical Asia, Australia, the 
Mascarene Islands, tropical and South Africa, and tropical 
and North America. Perianth tube none, the segments 
six, sub-equal, spreading; stamens six; ovary three-celled. 
To the species described on p. 171, Vol. II., the following 
should be added : 
H. colchicifolia (Colchicum-leaved), jl., perianth Ijin. in 
diameter, the segments bright yellow inside, greenish-yellow 
and slightly hairy on the back, oblong-lanceolate; peduncle 
slender, three- or four-flowered. Autumn. J. in a tuft about lft. 
high; produced ones six to eight, oblong or oblong-lanceolate, 
the largest 6in. to 8in. long, 1din. to 2in. broad, glabrous. Corm 
globose, 2in. in diameter. Cape of Good Hope, 1884. 
H. hemerocallidea (lemerocallis-like), The correct name of 
H,. elata. 
H. Baurit and H. villosa (SYN. H. pannosa) have also been 
introduced. 
HYPTIS (from hyptios, resupinate: the limb of the 
corolla is turned on its back). Syns. Brotera (of Sprengel), 
Hypothronia, Rhaphiodon, Schaueria. Orv. Labiate, A 
huge genus (about 250 species) of mostly stove herbs, 
under-shrubs or shrubs, of polymorphous habit and 
inflorescence, natives of the warmer parts of America. 
Calyx teeth five, usually acute or subulate; corolla sub- 
bilabiate, the lowest lobe abruptly deflexed ; stamens four, 
didynamous. Only one species calls for mention here. It 
is a greenhouse or half-hardy annnal, requiring ordinary 
treatment. 
H. suaveolens (sweet-smelling). Fis pale blue, rather pretty; 
corolla shortly exserted ; heads few-flowered, racemose-paniculate 
and axillary. J. petiolate, ovate, or the lower ones cordate, 
doubly serrated or almost sinuate. West Indies, &c., 1889. 
Syn. Ballota suaveolens.
