LYTHRARIEZ. A natural order of herbs, shrubs, 
or trees, with variable habit, natives chiefly of tropical 
America. Flowers hermaphrodite, very rarely unisexual, 
regular or rarely irregular, solitary in the axils of the 
leaves, or fascicled or cymose, sometimes spiked or 
racemed, and accompanied by floral bracteiform leaves, 
rarely panicled ; calyx very often free, persistent, tubular 
or campanulate, rarely urceolate. Leaves opposite or 
whorled, rarely opposite and alternate on the same plant, 
simple, penninerved, entire, petioled or sessile, sometimes 
glandular dotted, always exstipulate. There are about 
thirty genera and 250 species. ‘Illustrative genera are: 
Cuphea, Grislea, Lythrum. a 
LYTHRUM (from lythron, black blood; alluding to 
the colour of the flowers in some species). Loosestrife. 
ORD. Lythrariee. A genus comprising about twelve 
species of hardy or nearly hardy herbaceous plants or 
small shrubs. Flowers pink, purple, or rarely white, in 
the axils of the leaves, solitary, or in few-flowered, aggre- 
gate cymes. Leaves opposite, rarely verticillate or alter- 
nate, linear-oblong or lanceolate, entire. The species are 
of easy culture in ordinary garden soil, and may be freely 
increased by divisions. L. Grefferi is a very ornamental 
trailing plant, well adapted for cultivating in hanging 
pans or baskets for greenhouse. decoration in summer. 
It may readily be increased by cuttings. 
L. alatum (winged). f. of a beautiful purple, almost sessile, 
erect, six-petaled, furnished with two minute bracts. Summer 
and autumn. J. opposite, ovate-oblong, acute, rather cordate at 
the base, sessile, or nearly so. Branches twiggy, tetragonall 
winged. h. lft. to Aft. North America, 1812. An elegant half- 
shrubby plant, thriving best in sandy soil. (B. M. 1812.) 
L. Greefferi 8 ji. solitary in the axils of all the upper 
leaves, shortly pedicelled; calyx zin. long; tube slender ; 1 
twelve; petals longer than the calyx, bright pink. Summer 
and autumn. J. jin. to lin, long, all alternate, or the lower ones 
opposite, more or less oblong, or linear-oblong. A. lft. to Ift. 
South Europe. (B. M. 6499.) 
L. roseum (rose-coloured). A variety of L. Salicaria. 
L. Salicaria (Willow-like).* Common Purple Loosestrife. fl. 
reddish-purple, in whorled leafy spikes, almost sessile; petals 
six or seven. July. J. opposite, lanceolate, cordate at the base. 
h. 2ft. to 5ft. England. A handsome native pere rowing 
freely on the margins of streams and Its varieties are 
frequently very desirable, especially roseum and superbum.

MABA (its native name in the Tonga Islands). In- 
cluding Ferreola. ORD. Ebenacee. A genus comprising 
fifty-nine species of (mostly) hard-wooded, stove, ever- 
green trees or shrubs, dispersed over the warmer 
regions of the globe. Flowers diccious, rarely mone- 
cious or polygamous, axillary, or at the nodes of the 
year-old or older branches, solitary or shortly cymose; 
calyx campanulate; corolla campanulate or tubular; 
three, rarely four to six, contorted. Leaves alter- 
nate, often smaller than in Diospyros, rarely large. 
Mabas thrive in a peat and loam compost. Propagated, 
during May, by cuttings of half-ripened shoots, placed 
in sand, under a glass, and in à very gentle bottom 
heat. Probably the undermentioned are the only species 
introduced.

MACADAMIA (named after John Macadam, M.D., 
Secretary of the Philosophical Institute of Victoria). 
ORD. Proteacee. A small genus (two species) of green- 
house evergreen trees or tall shrubs, confined to Eastern 
Australia. Flowers pedicellate, in pairs, in simple, ter- 
minal or axillary racemes; perianth regular or slightly 
irregular. Leaves verticillate, entire or serrated. For 
culture, see Hakea. 
M. ternifolia (ternate-leaved).* fl. not showy, in a long-stalked 
raceme. fr. a kind of drupe, with a fleshy exterior, encircling a 
hard shell, like a Walnut ; it contains, at maturity, a kernel of a 
remarkably rich and agreeable flavour, resembling, although much 
superior to, the Filbert. L. in whorls of three or four, short- 
stalked, leathery, shining, oblong or ee og 
dentate at the margin, from 4in, to 12in. long. A. 
Tree. (G. C. 1870, 1181.) 
MACHZEIRANTHERA. This genus is now included 
under Aster, ~ 
MACHÆRIUM (from machaira, a sabre; in allusion 
to the pods ending in a sabre-shaped wing, which is longer 
than the fruit). ORD. Leguminose. A genus comprising 
nearly sixty species of stove erect trees or tall climbing 
shrubs, natives of tropical America. Flowers purple, 
violet, or white, small or mediocre, disposed in short, 
side-flowering racemes, fasciculate in the axils, or in ter- 
minal crowded panicles; calyx truncate, obtuse at base, 
shortly toothed; standard broadly ovate or orbiculate, 
exappendiculate, often silky outside; wings oblong, fre- 
quently falcate; keel incurved, the petals connate at back; 
pedicels short, sometimes very short. Pod compressed, 
samara-like, indehiscent. Leaves impari-pinnate; leaflets 
mostly alternate, exstipellate; stipules sometimes hard- 
bristly ; bracts small; bracteoles persistent. Some of the 
species are supposed to yield a part of the rosewood 
of commerce. Machæriums grow well in a compost of 
loam and peat. Propagation may be effected by cuttings, 
made of the ripened wood, and inserted in sand, under a 
glass, in heat. The undermentioned are probably the 
only species introduced; they are usually, but erroneously, 
classed as Nissolias. Both are climbing shrubs.

MACKAYA (named after Dr. J. F. Mackay, author of 
the “Flora Hibernica”). ORD. Acanthacee. A mono- 
typic genus, now included, by Bentham and Hooker, 
under Asystasia. M. bella is a beautiful greenhouse 
plant, which grows very freely, but requires special 
treatment to induce it to flower profusely. A know- 
ledge of its habit and mode of flowering is of material 
assistance, if not indispensable, for attaining success in 
its cultivation. Essential points are the encouragement of 
throughout the summer, in an airy, light 
structure, and the allowance of a season of rest in winter, 
during which time no water should be applied to the roots, 
or overhead. The plant is nearly, or quite, deciduous, 
and the racemes of flowers are produced from the 
points of nearly all well- ripened shoots. Cuttings root 
readily, during summer, in any close frame; and 
thus obtained, should be grown on as 
Taide presser the approach of winter. An 
occasional pinching will encourage a bushy habit, and 
cause new shoots to proceed from the base of the plant. 
Plenty of water, and frequent syringings, should be 
applied in the growing season, and a position afforded,
