Noctua, Plusia); hence, it is unnecessary to repeat 
here what is to be found under these headings, as to 
the form and habits of the moths. The larve are long 
and worm-like (see Fig. 266), not hairy, and generally 
dull green, brown, or yellowish in colour, with longi- 
tudinal lines and black dots, though sometimes orna- 
mented with brighter colours. They live hidden between 
the leaves of their food-plants, or underground upon 
roots of Turnips and other plants, and, unless looked 
for, are very seldom to be seen. Owing to their mode 
of life, they are apt to remain in Cabbages and other 
vegetables till cooked and sent to the table. It is hardly 
‘possible to get rid of them entirely, and the more so, 
since most of them feed largely on weeds, as well as on 
garden produce. Hadena oleracea sometimes gets the

are reddish-brown; there is a nearly white line parallel 
to the hind margin, and bent so as form a W nearly 
in the middle; the stigmas near the middle of the wing 
are margined with white scales, and the one nearer the 
tip (the reniform stigma) is of a dull ochreous colour. 
The hind wings are grey-brown, paler towards the

ORD. Aroideœ (Aracee). Of this genus, about forty species 
have been enumerated, but, according to the “ Genera 
Plantarum,” not more than twenty are really distinet. 
They are much-branched, tall, stove, climbing shrubs, with 
the lower branchlets rooting, and those at the summit 
spreading, and inhabit Asia, Australia, the Pacific Islands, 
and (one species) Madagascar. Spathe small, ovate or 
conchoid, rarely elongated, reflexed, green, accrescent or 
persistent; spadix shorter than the spathe, long-stipitate, 
clavate, globose, or ovoid, often decurved, sometimes 
twisted or flexnous, clothed with perfect flowers, each of 
which has a perianth of six segments, fornicate at apex; 
- peduncles leafy, sheathed, or naked. Leaves distichous, 
obliquely linear or ovate-lanceolate, the blade sometimes 
deficient; petioles winged or widened, and leafy. The 
species described below are the only ones worth growing, 
the others being more curious than ornamental. For 
culture, see Anthurium.

POTS AND POTTING. Pots are amongst the 
most essential of garden utensils, and on the proper 
execution of P depends materially the sunecess 
attained in plant culture. Potting is a general term 
meant to imply that a plant is being first placed in a 
Pot, or transferred from one size to another for providing 
additional rooting space. Pots are generally made of clay, 7 a — 
and as this varies in different localities, so do the articles 
made from it; from different potteries, too, the sizes and 
shapes vary considerably. In making Pots, a certain 
quantity of clay is called a “ cast”; this is worked to make 
the number by which the sizes are in many places dis- 
tinguished—thus, 48’s, 32’s, 24’s, &c.—the two lesser 
numbers taking respectively the same quantity of clay 
to the cast as the other, Soll eon inal eget
