- Latin peltātus, armed with a small shield, from Latin pelta, small shield, from Greek peltē. (American Heritage® Dictionary of the English Language, Fourth Edition)
Examples
“I have written of a lake, but no water was visible, for it was concealed by thousands and thousands of the peltate leaves of the lotus, nearly round, attaining a diameter of eighteen inches, cool and dewy-looking under the torrid sun, with a blue bloom upon their intense green.”
“The stems are green or reddish-green and the leaves show a considerable variation in form, but are normally 5-20 cm long, peltate, with 3-5 lobes.”
“The leaves are heart-shaped, 20 - 50 cm long, with rounded basal lobes; the leaf stalk joins the blade some distance inward from the notch between the lobes (ie the leaf is peltate - a feature which distinguishes the plant from the rather similar Xanthosoma).”
“Leaves are peltate, 60-90 cm in diameter on very long petioles and are often raised 1-2 m above the surface of the water.”
“_Tropæolum majus_, in which the ovules were replaced by perfect peltate leaves, is that the ovules are foliar productions springing, not directly from a prolonged floral axis, as in _Primulaceæ_, but from branches of the axis arising from the axils of the carpellary leaves.”
Vegetable Teratology An Account of the Principal Deviations from the Usual Construction of Plants
“= -- The leaves of Hazels may often be found with their margins coherent at the base, so as to become peltate, while in other cases, the disc of the leaf is so depressed that”
Vegetable Teratology An Account of the Principal Deviations from the Usual Construction of Plants
“From this point of view, peltate leaves like those of _Tropæolum_ or _Nelumbium_ become very significant.”
Vegetable Teratology An Account of the Principal Deviations from the Usual Construction of Plants
“Between such cases and that of a peltate leaf with a depressed centre, such as often occurs, to some extent, in _Nelumbium_, there is but little difference.”
Vegetable Teratology An Account of the Principal Deviations from the Usual Construction of Plants
“As the specific name implies, the leaves are peltate or umbrella-shaped, deeply lobed, each lobe being deeply cut, and all unevenly toothed and hairy at the edges, with a fine down covering the under sides; the upper surface is of a lively, shining green colour, and finely veined.”
“The leaves are nearly round in outline, sub-peltate, five, but sometimes only three-lobed; lobes entire, sometimes notched, smooth and glaucous; the leaf-stalks are long and bent, and act as tendrils.”
