Membranous, net-veined wings, those of the two pairs closely alike.
The principal entrance, reached by a flight of 23 steps, is ornamented with a portico supported by four black-veined marble columns.
Wings usually well developed, net-veined; the forewings of firmer texture than the hind-wings, whose anal area folds.
A remarkable fossil from the Scottish Coal-measures (Lithomantis) had apparently small wing-like structures on the prothorax, and in allied genera small veined outgrowths - like tracheal gills - occurred on the abdominal segments.
The prevailing formations appear to be granites which are veined with white quartz, and underlie old sedimentary brown sandstone and limestone formations.
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.
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 leaves, which show great variety in size and form, are generally broad and net-veined, but in sweet-flag (Acorus Calamus) are long and narrow with parallel veins.
The Comanchean system contains the oldest known remains of netted-veined leaved plants, which mark a great advance in the vegetable world.
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.
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.
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.
High, and white flowers tinted and veined with lilac, 3 to 5 in.
In vascular acotyledonous plants there is frequently a tendency to fork exhibited by the fibro-vascular bundles in the leaf; and when this is the case we have f ork-veined leaves.
These primary divisions may be again subdivided in a similar manner, and thus a feather-veined leaf will become bipinnatifid or bipinnatipartite; still further subdivisions give origin to tripinnatifid and laciniated leaves.
The stem is bushy, with numerous and very leafy branches; the leaves are alternate, leathery in texture, elliptical, obtusely serrated, strongly veined and placed on short channelled footstalks.
Their geological formation is metamorphic gneiss, veined with felspar and quartz, and interspersed with reddish porphyrite.
In some cases such as Delesseria, Neurymenia, Fucus, Alaria, the leaf-like structure is provided with a strengthening mid-rib, and when as in Delesseria it is also richly veined the resemblance to the leaf of a flowering plant is striking.
Among the chief edifices are the old church of St Martin; the town hall, with a Gothic facade; the law courts and the government offices, constructed, like many of the other buildings, of a peculiar veined brown sandstone found in the district.
Curiously veined veneers are obtained from the roots; and the root-shoots are largely employed in the making of crates, coalcorves or baskets, hurdles, withs and bands, whip-handles and other objects.
It is compact, of a fine grain, sometimes beautifully veined, and takes a high polish.
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 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.
SiK-rvov, a net, and the termination -rye pis, produced), a botanical name proposed by John Lindley for a class including certain families of Monocotyledons which have net-veined leaves.
The flowers have an urn-shaped calyx which persists around the fruit and is strongly veined, with five stiff, broad, almost prickly lobes; these, when the soft matter is removed by maceration, form very elegant specimens when associated with leaves prepared in a similar way.
The long, parallel-veined leaves of the Cordaiteae, which were commonly referred to Monocotyledons before their structure or connexion with other parts of the plant was known, have been shown by Renault to have essentially the same anatomy as a single leaflet of a Cycad such as Zamia.
For the architectural embellishment of the city the finest building material was procurable without difficulty and in abundance; Pentelicus forms a mass of white, transparent, blue-veined marble; another variety, somewhat similar in appearance, but generally of a bluer hue, was obtained from Hymettus.
