THE DICTIONARY OF GARDENING, 
OREOPANAX (irom oreos, a mountain, and Punaz; 
ing to the relationship of the plants to Panaz, and 
their natural habitats). ORD. Araliacee. A genus of 
glabrous or tomentose, stove shrubs or trees, allied to 
Hedera. Sixty-four species have been enumerated, but 
this number may be reduced; they are natives of tropical 
America, mostly in the region of the Andes. Flowers 
capitate, racemose, or paniculate, sessile, each provided 
with two or three bracts; stamens equal in number to 
the valvate petals; ovary three to five (rarely six or 
seven) celled, surrounded by as many styles. Leaves 
entire, palmately lobed or digitately compound ; lobes or 
leaflets entire or argutely toothed. All the species thrive 
in good loam, and require abundance of water during 
the summer months. During the dull winter season, 
when the plants are at rest, but little water will be 
needed. Propagated by cuttings of the young shoots. 
The species here described are probably the only one 
yet introduced, ;

ORGYIA ANTIQUA, or VAPOURER MOTH. 
This is one of the most widespread of injurious 
insects, and is common even within the limits of 
London. Its larve are at times very hurtful to 
deciduous trees and shrubs of many kinds. The male 
moth is shown of the natural size in Fig. 774.
