ALISMACEZ. A small order of aquatic or marsh 
plants, with three-petaled flowers, on leafless scapes, and 
simple radical leaves. The genera best known are Alisma 
and Sagittaria.

ALLAMANDA (named in memory of Dr. Allamand, 
of Leyden, who first communicated seeds of this genus to 
Linnens). ORD. Apocynacee. Elegant climbing ever- 
green stove plants. Peduncles terminal and many-flowered; 
corolla funnel-shaped, with a narrow tube, gamopetalous, 
_ large, inflated, five-cleft at the apex. Leaves verticillate. 
_ This genus differs from all éthers of the same order, in the 
sin figure of the corolla. Of comparatiyely easy culture. To 
-~ Obtain their beauty df foliage and flowers, the shoots 
should be tied to wires placed within 8in. or Qin. of the 
aier that forms the roof of the structure in which the 
_ Plants are growing. Trained in this way, and the shoots 
_ allowed to ramble in a somewhat natural manner, the effect, 
when the plants are in flower, is grander and more pleasing 
r 
m i every respect than when the shoots are tied to a formal |

trellis, of whatever shape. When thoroughly established, 
they succeed admirably in a compost of three parts good 
fibry loam, and one part wood charcoal or coarse river 
sand, with some rotten cow manure added. When potting 
the plants, ‘make the fresh compost firm round the old 
balls of soil, and do nof fill the pots too full; leave 
room for plenty of water, as, when in ae growth, they 
require a liberal daily supply. They must be pruned 
annually in January or February, cutting the previous 
year’s shoots back to within a joint or two of the old wood. ~ 
Allamandas should be exposed to the light as much as’ pos- 
sible at all seasons of the year. In winter months they 
require but little water, but the drainage must always be 
perfect. They are remarkably free from insect attacks of 
any. kind. It may be also observed that the temperature 
should never fall below 55deg. This genus is easily pro- 
pagated by cuttings, which will root at any time of the 
year in a bottom heat of from 70deg. to 80deg. The usual 
time is, however, in spring, when the old plants are pruned 
ee Choose the tops of the shoots, retaining two or 
joints to each cutting; place these in a compost 
of sand and peat or leaf mould in equal proportions, 
singly, in small pots. Press the soil firmly around 
each cutting, and, when all are inserted, give a good. 
watering, and plunge the pots in the propagating bed. 
Attend to shading and watering, and in about three 
weeks’ time they will have emitted roots, and started to 
grow at the tops. The pots should now be raised out of 
the plunging material, and placed upon the surface thereof, 
and there allowed to remain two or three weeks longer; 
when the young roots will have, by this time, filled the 
little pots, and a shift into the larger ones will be necessary. 
Return the plants to the propagating bed, but do not 
plunge them therein. As soon as it is certain that the roots 
have commenced growth in the fresh soil, pinch the point 
of each plant that is intended to be grown on a trellis. This 
will cause the remaining buds to push out fresh shoots; 
and these, as soon as they have made two joints or 
whorls of leaves each, should have their points pinched out 
also. By repotting the plants as often as they fill their 
pots with roots during the first season of their growth, and 
pinching the points out of the shoots twice or thrice in the _ 
same time, a good foundation will be formed, from which 
the future specimens will spring. In the case of plants 
intended to be trained up rafters or pillars, they should 
not have their points pinched out until they attain to the 
height where it is desirable they should have more than 
-one shoot, and be repotted as recommended above, for 
the first year; but, after that, they will require to be 
repotted only once a year, and this should be done soon 
after the buds have started to grow afresh in the 
spring. i
