were inserted on the top of the branch the operation would result in
failure, as the birds would devour them.
Mitella Diphylla.--A hardy perennial which bears slender racemes of
white flowers in April. It makes a pretty rock plant, delights in a
peat soil, and is increased by division of the root. Height, 6 in.
Moles.--These pests may be destroyed by placing in their runs worms
that have been kept for some time in mould to which carbonate of
barytes has been added.
Monardia Didyma (Oswego Mint, or Horse Balm).--See "Bergamot."
Monetia Barlerioides.--An ornamental shrub, suitable for the
greenhouse or stove. It requires to be grown in loam and peat, and
may be increased by cuttings planted in sand, under glass, in a
bottom-heat. Height, 3 ft.
Monkey Flower.--See "Mimulus."
Monkey Puzzle.--See "Araucaria."
Monk's-hood.--See "Aconite."
Montbretia.--Very graceful and showy plants. The flowers, which are
like small Gladioli, are produced on long branched spikes and are
excellent for cutting. Plant 3 in. deep and 2 in. apart in sandy loam
and leaf-mould. The corms should never be kept long out of the ground,
as they shrivel, and weak growth and few flowers are the result.
Though they are hardy it is well to give them a covering of litter in
winter. They may also be grown in pots. Height, 2-1/2 ft.
Moraea Iridioides.--These plants flower in May, and require the same
treatment as Ixias.
Morina (Whorl Flower).--An ornamental hardy perennial, which is
seldom met with. It forms rosettes of large, deep green, shiny foliage
and stout spikes of rose-coloured flowers in whorls, which make it one
of the most attractive of Thistles. It likes a rich, light soil, is
increased by seed sown in the autumn, also by division in August, and
flowers in July. Height, 21/2 ft.
Morisia Hypogaea.--This is a pretty hardy perennial for rock-work. It
flowers in May, and is raised from seed sown as soon as it is ripe.
Height, 2 in.
Morna Elegans.--Beautiful half-hardy annuals. For early flowering sow
the seed in September: for later blooms sow in February in slight
heat, pot off, affording good drainage to the plants. They are very
sensitive to cold, and should not be placed out of doors before the
end of May. Avoid over-watering, as this would prove fatal to them.
The soil should be light and sandy. Those sown in September will bloom
in the greenhouse in May; those sown in February will flower in the
