‘ARAGEe or AROIDEZ.. An extensive order of her- 
baceous plants, with tuberous rhizomes. Flowers on a spadix, 
unisexual or hermaphrodite, protected by a spathe. Leaves 
large, radical. Well known genera belonging to this order 
are: Alocasia, Arum, Caladium, Colocasia, and Dieffenbachia. 
ARACHIS (from a, without, and rachis, a branch; 
plant branchless). Ground or Earth Nut. ORD. Legumi- 
nose. A stove annual, of economical value. Corolla resu- 
pinate ; calyx a long tube, with a bilabiate limb; ovary 
stipitate, inclosed in the tube of the calyx; the stipe 
at first short, but afterwards becoming elongated. Sandy 
ʻ loam is the soil most suitable for their cultivation. Seeds 
should be sown in heat; and, when the plants have grown. 
to-a sufficient size, they should be potted off singly, and 
placed among other stove annuals. After the plant has 
finished flowering, and the pods begin to lengthen, the pe- 
pes force them into the earth, where they ripen their seeds.

ARALIA (meaning unknown). ORD. Araliacew. This 
widely-grown genus includes stove, greenhouse, and hardy 
herbaceous and shrubby plants. Flowers inconspicuous, 
- umbellate, the umbels usually disposed in panicles; petals 
five, inserted on the margin of the disk; stamens five. 
See Fig. 142, Leaves usually compound. These plants are 
of moderately free growth, and the majority are easy to 
manage. Those requiring indoor treatment thrive well 
under the ordinary routine of management. One most im- 
portant requirement, however, is that they must be kept 
well supplied with water at the roots. The finer, or stove 
varieties, should be potted in a mixture mainly composed of 
sandy loam and peat, with the addition of a little leaf soil of 
a fibrous description, and sufficient sand to keep the whole 
porous. The stronger growing kinds thrive in a richer com- 
post, therefore a moderate portion of well decomposed dung 
may be added to the mixture given above. Propagation 
by cuttings of the roots is a common and very successful — 
method. To obtain the roots, one of the strongest plants 
should be turned out of the pot, and the roots should 
be cleared of soil by shaking or washing it out; the 
requisite number of pieces should then be selected. 
As each piece is removed, it should have the end nearest 
the stem cut horizontally, to distinguish it from the other 
‘or furthermost end. In planting cuttings of the roots, 
it is best to place the end nearest the stem uppermost. 
The. pieces may ae ee ae we onl be

inserted in pots, well drained, and filled with sandy suil, 
leaving the tops of the cuttings about level with the surface 
of the soil. A square of glasssmust be placed over the top 
of each pot, plunging them in moderate bottom heat. The 
stems of the plants from which the roots have been taken 
may be cut into pieces lin. or 1}in. long, leaving an eye or 
bud near the top; a slice of half the shoot may be taken off 
opposite the bud. When prepared, these pieces should be — 
pressed into pots of sand or sandy soil, and plunged into

turbing the roots; in that case, if the pots are plunged in 
bottom heat, and kept moderately supplied with water, 
they will probably throw up several suckers or shoots from 
the roots. These, if taken off with a portion of root to 
each, and placed in small sized pots, will, with a little 
care, soon make useful plants. All the hardy species and 
most of the greenhouse ones are propagated readily by
