possess. It has a 'wide geographical 
range, as in it are found both stove and 
greenhouse plants, along with others 
perfectly hardy, or natives of our own 
country. The tender species should be 
grown in pots of any rich soil, and must 
be frequently topped to keep them at all 
within bounds. The hardy kinds may 
be placed in shrubbery borders were 
little else will thrive. 
MALVAYISCUS (De Candolle.) 
Nat. Ord. Malvaceae. Handsome stove 
plants, bearing large rich scarlet flowers. 
They grow freely in peat and loam, with 
ordinary attention. 
M AMMILL ARI A (Haworth.) Nat. 
Ord. Cadacece. The name employed to 
designate this interesting group of suc¬ 
culents is very expressive of their singular 
conformation, as they are readily distin¬ 
guished from Echino and Melo-cactus 
by their protruding tubercles, which 
resemble teats. Mammillaria being de¬ 
rived from mamma , the nipple. Eor 
culture, they may be referred to Echi- 
nocactus, being precisely similar in 
habit. It is quite unnecessary to select 
from this genus, for all are interesting, 
and well deserve the little attention re¬ 
quisite to grow them well. 
MANETTIA (Metis.) Nat. Ord. 
Cinchonaceae. An elegant family of stove 
climbers, suitable for training, over wire 
trellis attached to the pots in which the 
plants grow. The species delight in 
peat and loam, with a moderately warm 
and moist atmosphere when they are 
growing, and in the case of having tube¬ 
rous roots, like glabra or cordata , are all 
the better for a decided drying through 
the winter; the other species, from hav¬ 
ing only fibrous roots, will not bear a 
reduction of the same extent. M. bicolor 
is a winter flowering plant; it should be 
grown freely through the summer, and 
afterwards be placed in a dry warm po¬ 
sition to induce it to flower freely, and 
to preserve its foliage from mildew, to 
which it is very subject; the flowers of 
this species are yellow and crimson, 
those of the others are scarlet, except 
Lygistum , which has pink blossoms. 
MARICA (Schreber.) Nat. Ord. 
Iridacece. Beautiful South American 
plants, requiring ordinary greenhouse 
treatment with which they usually 
flower freely; their blossoms resemble 
those of the Iris, and are blue, yellow, 
white, or striped. M. coelestis, ccerulea , 
humilis paludosa, and Northiana are very 
desirable 
MARSHALLIA (Schreber.) Nat. 
Ord. Composite. Pretty half-hardy plants, 
producing purple flowers. They grow 
well in peat and loam, and are easily 
increased by cuttings treated in the 
usual manner of such plants. 
MARTYNIA (Linn.) Nat. Ord. Pe- 
daliacece. These annuals are remarkable 
for the very large size and rich colour 
of then flowers, especially the species 
fragrans. The seed should be sown in 
March, on a brisk hot-bed, and their 
after-management may be assimilated 
with that of the Balsam and similar 
tender annuals. 
MATHIOLA (R. Brown.) Nat. Ord. 
Crucifer (B. In this genus we have the 
well-known Stock in all its multifarious 
varieties ; these for the purposes of cul¬ 
ture are classed in two divisions: the 
biennial kinds, as the Brompton, Queen, 
&c., and the annual or ten-week stocks. 
The former require to be sown the season 
previous to that in which they flower; 
they do best when sown in April in the 
open air, allowing them to grow up 
strong, and when about two inches high 
they should be potted singly into small 
pots; this is for the purpose of protect¬ 
ing them through the winter, as in very 
severe weather, or a long continuance of 
wet, they perish; but potted and placed 
in a frame they are perfectly safe, and 
in the succeeding spring may be placed 
where they are to bloom; when the 
convenience of a frame cannot be af¬ 
forded them, and the winter is likely to 
be severe, the pots should be placed 
closely together, and hoops being bent 
over them, protection may be afforded 
with mats, &c. The other class, includ¬ 
ing all those which bloom the same 
year they are sown, require much less 
trouble; if the seed is sown on a pre¬ 
pared border, having a southern aspect, 
about the end of Eebruary, and it is 
covered with a common hand-glass, the
