Most Apiaceae are annual, biennial or perennial herbs ( frequently with the leaves aggregated toward the base ), though a minority are shrubs or trees.

Their leaves are of variable size and alternately arranged, or alternate with the upper leaves becoming nearly opposite.

The leaves are 3 – 5 inches long, with a serrated margin and a petiole.

The flowers are white to pale pink, diameter with five petals, produced singly or in pairs and appearing before the leaves in early spring.

With a few exceptions, alders are deciduous, and the leaves are alternate, simple, and serrated.

" They lived in unwalled villages, without any superfluous furniture ; for as they slept on beds of leaves and fed on meat and were exclusively occupied with war and agriculture, their lives were very simple, and they had no knowledge whatever of any art or science.

The leaves are usually alternate or whorled, simple and without stipules, and hermaphrodite flowers.

The leaves of Polygonaceae are simple, and arranged alternately on the stems.

Asimina is a genus of eight species of small trees or shrubs with large simple leaves and large fruit, native to eastern North America, collectively referred to as Pawpaw.

The leaves are alternately arranged, simple, 2 – 12 cm long, glossy green on some species, densely silvery-hairy in some others ; leaf shape varies from broad oval to narrow lanceolate.

# Every simple path from a given node to any of its descendant leaves contains the same number of black nodes.

Gun salute by aircraft, primarily displayed during funerals, began with simple flypasts during World War I and have evolved into the missing man formation, where either a formation of aircraft is conspicuously missing an element, or where a single plane abruptly leaves a formation.

In a simple genus, containing only two species, it was easy to distinguish them apart with a one-word genus and a one-word specific name ; but as more species were discovered the names necessarily became longer and unwieldy, for instance Plantago foliis ovato-lanceolatus pubescen tibus, spica cylindrica, scapo tereti ( Plantain with pubescent ovate-lanceolate leaves, a cylindric spike and a terete scape ), which we know today as Plantago media.

The leaves are simple ovate-lanceolate, long,, and are attached to short petioles.

Most have simple leaves, but the genera Aruncus and Sorbaria have pinnately compound leaves.

The leaves are evergreen, alternate, simple, long and broad ; when the leaves are young they are orange-pink, rapidly changing to a dark, glossy red, then dark green as they mature.

The nest consists of a simple scrape in the ground, lined with grass and leaves.

The leaves are simple and alternate, without stipules.

The leaves are opposite ( rarely in whorls of three ), and mostly pinnately compound, simple in a few species.

Typha leaves are alternate and mostly basal to a simple, jointless stem that eventually bears the flowering spikes.

Clubmosses are thought to be structurally similar to the earliest vascular plants, with small, scale-like leaves, homosporous spores borne in sporangia at the bases of the leaves, branching stems ( usually dichotomous ), and generally simple form.

Selaginellas are creeping or ascendant plants with simple, scale-like leaves on branching stems from which roots also arise.

The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate.

The alternate, simple, spiral leaves have serrate or entire margins.

The leaves are alternate, simple, with a dentate margin and a long petiole.

This root gives off at the surface of the ground a rosette of ovate-oblong to ovate, wrinkled, crisp, sinuate-dentate to entire leaves, long, somewhat resembling those of the tobacco-plant.

The leaves are ovate, long and wide, with a rounded base, a pointed tip and a finely serrated margin.

The leaves are evergreen, alternately arranged, ovate to lanceolate, long and broad, with an entire margin, dark green to grey-green in colour.

Basal leaves are ovate or oblong-lanceolate, upper leaves and bracts are ovate-lanceolate and sheathing.

The leaf morphology of the species within the genus is extremely varied, ranging from the sessile ovate leaves of D. erythrorhiza to the bipinnately divided acicular leaves of D. binata.

The leaves are alternate, simple, ovate to triangular-based, very variable in size from about 2 – 30 cm long and 1 – 15 cm broad, with larger leaves at the base of the plant and small leaves higher on the flowering stem.

Guavas are typical Myrtoideae, with tough dark leaves that are opposite, simple, elliptic to ovate and long.

The leaves are opposite, simple, ovate, 6 – 13 cm long and 4 – 6 cm broad, with an apparently entire margin ( actually very finely toothed, under a lens ); they turn a rich red-brown in fall.

The crabapple has ovate leaves which are three to four inches long.

Plants grow to tall with long ovate leaves.

The leaves are alternate, ovate to lanceolate, often with a toothed or lobed margin.

The leaves are opposite, ovate, pinnate, 3 – 10 cm long, and emerald green when new, maturing into a dark green.

The leaves are variably deciduous to evergreen ( with D. barbara tending to be more often deciduous, D. sinensis more evergreen ), 3-10 cm long, ovate with an acute apex, and a smooth to obscurely toothed margin.

The leaves are alternate, 4 – 8 cm long, ovate, and coarsely toothed.

The often hairy leaves can vary from ovate to elliptic or lanceolate, folded along their length.

In selected species, the short, ovate leaves grow alternately over the whole length of the stems, in others, the leaves are bunched towards the apex of the stem ( e. g. Dendrobium tetragonum ).

Scarlet pimpernel has weak sprawling stems growing to about 50 cm long, which bear bright green ovate sessile leaves in opposite pairs.

The shrubby plant is many-branched, with alternate leaves, thick and shiny, round to ovate in shape.

The juvenile leaves in all species are larger than the adult, more or less acute, varying among the species from ovate to lanceolate.
