The tribe Smilacoideae, shrubby climbers with net-veined leaves and small unisexual flowers, bears much the same relationship to the order as a whole as does the order Dioscoreaceae, which have a similar habit, but flowers with am inferior ovary, to the Amaryllidaceae.
The genus is a member of the natural order Smiliaceae, and constitutes the tribe Smilacoidide, characterized by its climbing habit, net-veined leaves and dioecious flowers.
Smilacoideae are climbing shrubs with broad net-veined leaves and small dioecious flowers in umbels springing from the leaf-axils; the fruit is a berry.
Structurally the Neuroptera are distinguished by elongate feelers, a large, free prothorax, a labium with the inner lobes of the second maxillae fused together to form a median ligula, membranous, net-veined wings without hairy covering, those of the two pairs being usually alike, the absence of abdominal cerci, and the presence of six or eight Malpighian tubes.
Membranous, net-veined wings, those of the two pairs closely alike.
They are large perennial climbers growing from short thick underground stems, from which rise numerous semi-woody flexuous angular stems, bearing large alternate stalked long-persistent and prominently net-veined leaves, from the base of which spring the tendrils which support the plant.
The Myrmeleonidae are large insects with short clubbed feelers on their prominent heads, and two pairs of closely similar net-veined wings, with regular oblong areolets at the tips.
As first used by Linnaeus (1735) it included all insects with mandibulate jaws and two pairs of net-veined wings - dragon-flies, May-flies, stone-flies, lacewing-flies and caddis-flies - and it has been employed in the same wide sense by D.
