=A. Douglasii= (Douglas). Synonymous with _A. glabrum_.
=A. eriocarpon= (hairy-fruited). Synonymous with _A. dasycarpum_.
=A. Ginnala= (Ginnalian).* _fl._ on compound, crowded, erect
racemes. Amur River. This is generally classed as a variety of _A.
tartaricum_, but its habit is much more graceful, and in this form
the leaves are prettily cut and lobed, whilst the leafstalks and
midrib are more deeply coloured.
=A. glabrum= (smooth).* _fl._ corymbose, on short two-leaved
branchlets, greenish-yellow. June. _l._ roundish-cordate, deeply
three to five-lobed, or partite; the lobes biserrate, of a

_l._ many-lobed, in early spring very light green. _h._ 20ft.
Japan, 1863. The varieties of this species, although not well fixed
in many cases, rank amongst the most handsome of the deciduous
small shrubs grown, but often change in character as they attain
any considerable size. Plants from 1-1/2ft. to 3ft. high are very
useful in cool conservatories, and in the highly kept grounds
surrounding the house.
=A. laurifolium= (laurel-leaved). Synonymous with _A. oblongum_.

oblong, acuminated, deeply serrated. _h._ 30ft. Japan, 1845.
=A. p. ornatum= (beautiful).* Very ornamental, having finely cut
deep red leaves, with lighter midribs. Japan, 1871. This variety is
also known as _dissectum_.
=A. p. palmatifidum= (palmatifid).* _l._ very finely palmately
divided, the lobes cut down quite to the midrib, of a beautiful
light green colour. 1875.
=A. p. reticulatum= (netted).* _l._ palmately seven-lobed; lobes
unequal, sharply serrate, emerald green, with dark green veins.
Japan, 1875. A very elegant variety, with slender branches.
=A. p. roseo-marginatum= (rose-margined).* _l._ freely divided, the
lobes deeply cut, light green, margined with rose. Japan, 1874. A
very distinct and charming variety.
=A. p. sanguineum= (blood-red).* _l._ deeply five-lobed, the lobes
serrated, of a deep reddish-crimson colour, much brighter than
the variety _atropurpureum_. 1874. This presents a very striking
contrast to the last.
=A. p. septemlobum= (seven-lobed).* _fl._ purplish, on numerous
flowered umbels. Spring. _l._ varying much, from palmately
five-lobed, with toothed undivided lobes, to deeply seven to
nine-lobed, with more or less finely cut divisions. Japan, 1864.
There are numerous beautiful forms of this variety.
There are many varieties of this much varying species, but we have only
mentioned those best known; many are only known by their native names,
and there is some doubt as to their distinctive characteristics. They
are all extremely handsome.
=A. pennsylvanicum= (Pennsylvanian).* _fl._ in long drooping,
simple racemes. May. _l._ cordate, three-lobed, acuminated, finely

(converging), _A. p. marmoratum_ (spotted), _A. p. rubrum_ (red),
and _A. p. variegatum_ (variegated), are varieties differing
principally in the colouring of the leaves. All are very desirable.
=A. platanoides= (plane-like).* The Norway Maple. _fl._ on nearly
erect stalked corymbs. May, June. _l._ cordate, smooth, five-lobed;
lobes acuminated, with a few coarse acute teeth. _h._ 50ft. Europe,
1683. A very ornamental hardy tree, growing with great rapidity
when young. It prefers a deep, well-drained soil.
=A. p. aureo variegatum= (golden-variegated).* _l._ variegated with
yellow. Europe, 1383. This, to retain the variegation, requires to
be propagated by budding or grafting. The same remarks are equally
applicable to the other varieties.
=A. p. laciniatum= (cut-leaved).* _l._ deeply and variously cut,
green and yellow.
=A. p. Schwedleri= (Schwedler's).* _l._ very large, deep
bronzy-red. A vigorous grower, and most effective.

There are several other varieties, but of less importance than the
foregoing.
=A. Pseudo-platanus= (Mock-plane tree).* Sycamore. _fl._ on rather
compound pendulous racemes. May. _l._ cordate, with five acuminated
unequally-toothed lobes. _h._ 30ft. to 60ft. Europe. There are
few deciduous trees so well adapted for standing singly in rough
exposed situations. A deep, soft, dry soil is most suitable for it,
but it will grow in soils of very opposite qualities.
=A. P. albo variegata= (white-variegated).* A very beautiful form,
in spring especially. _l._ white and green.
=A. P. flavo variegata= (yellow-variegated). _l._ variegated with
yellow.

when slightly ruffled by the wind, alternately appearing clothed
in purple and pale green. Numerous other varieties of more or less
excellence are grown.
=A. rubrum= (red).* Scarlet Maple. _fl._ scarlet, handsome,
conglomerate, corymbose. _l._ cordate at the base, deeply and
unequally toothed, palmately five-lobed, with acute recesses.
Branches and fruit also scarlet. _h._ 20ft. Canada, 1656. A variety
with leaves splashed with yellow is rare. An excellent species,
thriving well in damp, swampy situations, and is commonly increased
by layers.
=A. rufinerve= (red-nerved).* "The leaves vary both in size and
outline, from 2-1/2in. to 4in. each way; three to five-lobed, with
irregularly toothed margins, glabrous above, but with reddish
hairs along the nerves beneath. The young branches are conspicuous
on account of the bluish-grey glaucescence with which they are
covered."
=A. r. albo-limbatum= (white-margined).* differs only from the
species in having a very distinct white margin--not always
constant. Japan, 1869.
=A. saccharinum= (Sugar Maple).* _fl._ yellow, on drooping corymbs,

Buds, fruit, and young leaves, silky, villous. _l._ cordate,
five-lobed, villous beneath as well as the petioles; lobes ovate
acute. _h._ 50ft. Himalaya, at high elevations. Not hardy.
=A. virginianum= (Virginian). Synonymous with _A. dasycarpum_.
=ACERACEÆ.= An order of very ornamental hardy trees, of which the
sycamore and maple are well-known representatives.

spur). ORD. _Orchidaceæ_. An interesting genus of terrestrial orchids.
Calyx of three ovate, equal, converging sepals; petals two, narrow,
oblong; lip spurless, much longer than the calyx, narrow, oblong, with
four linear lobes. The most interesting species is the native one.
Indigenous to dry, chalky pastures in the south-east of England, and it
will only thrive in similar soils when grown in gardens. Propagated by
careful divisions of tubers only.
[Illustration: FIG. 10. FLOWER OF ACERAS ANTHROPOPHORA.]

a long spike, lip longer than the ovary; lip and petals often
margined with red. June. _l._ lanceolate. _h._ 1ft. See Fig. 10.
=ACERATIUM= (from _a_, not, and _keras_, a horn; the stamens being
destitute of the terminal bristles so conspicuous in its near ally,
_Elæocarpus_). ORD. _Tiliaceæ_. An interesting stove evergreen tree,
very closely allied to _Tilia_. It thrives well in a mixture of loam
and peat, and is increased by ripe cuttings, which root readily if
placed in sand, under a hand glass, in heat.
=A. oppositifolium= (opposite-leaved).* _fl._ white, on terminal
three-flowered peduncles. June. _l._ opposite, elliptic-oblong,

ternate, simple or compound. All the species are easily cultivated in
ordinary garden soil. _A. Eupatorium_ and other large-growing kinds are
well suited for borders or groups, whilst the alpine section should be
planted on the rockery. A great number of species, although excellent
for naturalising in rough shrubberies, are totally unfitted for garden
culture. Propagated, during spring, by root divisions, cuttings, and
seeds.

Eupatorium_.
=A. Herba-rota= (Herba-rota).* _fl.-heads_ white, in lax corymbs,
on slender stems. May. _l._ lanceolate, serrated. _h._ 6in. France,
1640. When touched, this pretty little plant gives off an agreeable
aromatic perfume. To attain full beauty it requires sandy loam and
a sunny position.
_A. macrophylla_ (large-leaved). _fl.-heads_ white. July. _l._ long
and broad pinnate; leaflets horizontal. _h._ 3ft. Italy, 1810.

=ACHIMENES= (from _cheimaino_, to suffer from cold; alluding to
the general tenderness of the species). Including _Scheeria_. ORD.
_Gesneraceæ_. A large genus of handsome, stove or warm greenhouse,
branched, generally hairy, herbaceous perennials, with scaly,
catkin-like stolons underground (see Fig. 14), and sometimes from
the axils of the leaves. Corolla funnel-shaped; tube rather oblique,
gibbous behind at the base; pedicels one-flowered, axillary, solitary
or fasciculated, bracteated. Leaves opposite, or three in a whorl,
serrated.
[Illustration: FIG. 14. ROOT OF THE ACHIMENE, showing Tubercles.]
[Illustration: FIG. 15. BOUQUET OF VARIOUS ACHIMENES.]
To be successfully cultivated, they must be started and grown in stove
heat till they commence flowering, when they may be removed to the
conservatory or greenhouse, there to remain till after flowering.
Batches of tubercles should be started in heat from February till
the end of April, so as to give a succession of blossom. Shake each
variety out of the old compost and insert separately in light, sandy
soil; water sparingly at first, but when active they may receive
more frequent supplies. When the shoots are about 2in. high, the
tubercles may be transplanted to the pots, pans, or baskets in which
it is intended to grow them, using as potting compost fibrous peat and
leaf-soil in equal proportions, with about a sixth part of sheep's or
rotten cow manure, and sufficient silver sand to make the whole porous
and of a whitish appearance. Thorough drainage is indispensable, and
a layer of the rougher soil, or sphagnum, should be placed over the
potsherds, to prevent the loose soil stopping the drainage. Place the
pans as near the glass as possible, and shade from bright sunshine.
Give liberal supplies of water, with occasional doses of liquid manure;
and, as the shoots lengthen, they may be pinched, to induce sturdy
growth and a larger number of flowering branches. Place neat stakes to
each stem, and keep well tied, arranging the stakes as symmetrically
as possible, so as to ensure an even outline, but do not allow them
to be seen. Light syringing with clear water, morning and evening, is
beneficial. After the plants have done flowering, they should gradually
have less water as the foliage and stems decay; a light airy situation
is needed to mature and ripen the tubers. When the tops are quite dead,
they may be removed, and the pots stored on the sides in any warm dry
corner where the temperature will not fall below 50deg., keeping
the plants quite dry until the time of starting again. Achimenes are
liable to attacks of thrips, red-spider, and green-fly, especially if
the atmosphere is kept dry; these are easily destroyed by fumigation
with tobacco. This must only be done when the foliage is quite dry,
otherwise the plants will suffer. Achimenes are especially beautiful
when well arranged, especially if two or three varieties are mixed
together, as white, red, and purple (Fig. 15). There are several
methods of increasing these:--(1) By cuttings; these need not be cut
off at a joint, as they will root from any portion of the stem. Insert
them thickly in well-drained pots of sandy soil--say a mixture of equal
parts of peat and sand--and place in bottom heat. (2) By leaves, which
should be severed from the stems, and pricked in pots of similar soil
to the cuttings, placing all the petiole below the surface; stand the
pots in bottom heat. (3) By scales from the corms, which should be
carefully rubbed off and sown, like seeds, in pots or pans of the same
compost, barely covered with sand, and placed in bottom heat. (4) By
seeds, which are very small, and, consequently, require to be carefully
sown. The pans must be thoroughly drained and filled nearly to the
rim, levelled, and well watered with a fine rose, after which the seed
should be thinly scattered, covered very lightly with sand, and placed
in a shady position. Keep nicely moist, and apply water very lightly,
or the tiny germs will be disturbed. Place a sheet of glass over the
seed-pans. When the seedlings are large enough to handle, they may be
pricked off and afterwards treated like rooted cuttings. The best time
for all modes of propagating is early spring.
