stipule

The stipule was cut and had an entire central lobe.

They are simple, opposite leaves, with aromatic glands and no stipule.

Each is accompanied by a small, pointed stipule.

Each leaf has a large stipule which forms a wide, membranous ochrea.

In some older botanical writing, the term "stipule" was used more generally to refer to any small leaves or leaf-parts, notably prophylls.

The family is characterized by opposite leaves that may be simple or compound (either pinnate or ternate), without stipule.

Each reddish leaf has a funnel-shaped stipule that wraps around the leaf base to form an ochrea.

It bears a stipule up to half the petiole length which hosts many simple straight hairs in addition to some glandular hairs.

A stipule, present on the leaves of many dicotyledons, is an appendage on each side at the base of the petiole resembling a small leaf.

The crowding of the leaves results in a pattern of stacked, inverted cones due to the overlapping of the stipule sheaths.

Psychotria; other subgenera of Psychotria lack the well developed reddish brown trichomes inserted above the stipule scars].

The opposite-leaved appearance of some species is unusual in that one stipule is enlarged giving the appearance of opposite ["paired"] leaves.

Mr. Scanniello's face said no. "Look at the stipule," he said, showing us a little green wing at the base of one of the leaf stalks.

Stuckenia vaginata is 1-4 metres long and has longer stipule sheaths than e.g. Stuckenia pecinata and Stuckenia filiformis.

Pistil- late flowers are borne in pairs at the nodes one on each side of the petiole behind the stipule of bracts (reduced leaves) which conceal the flowers.

Ficus triradiata, commonly known as the red stipule fig is a hemiepiphytic fig that is endemic to the wet tropical rainforests of northeastern Queensland, Australia.

Étroubles [Estroble], /Ettruglie/, (Etroble, Stipule)

On the upper stems of Psychotria viridis these features are obscured by a stipule (see below), which covers the trichomes; the scar actually marks the point where this structure has fallen off.

The first sign of flowering in Cannabis is the appearance of undifferentiated flower primordia along the main stem at the nodes (intersections) of the petiole, behind the stipule (leaf spur).

However, stipule shape and size is quite variable among different plants, and also depends on the stipule's developmental stage and other factors such as whether the stem that produced it is reproductive or vegetative.

Stipules may be lasting and not be shed (a stipulate leaf, such as in roses and beans), or be shed as the leaf expands, leaving a stipule scar on the twig (an exstipulate leaf).

The main difference from other narrow-leaved pondweeds is that the stipule joins the leaf base, when it is pulled the sheath and stipule comes away, similar to a grass sheath and ligule.

While Nothofagus shares a number of common characteristics with the Fagaceae, such as cupule fruit structure, it differs significantly in a number of ways, including distinct stipule and pollen morphology, as well as having a different number of chromosomes.

Most species, however, are shrub or tree-like, ranging in height from 5 m or less to as much as 12 m. All species save one have spines on their branchlets, which are a modified form of stipule; some species have spines in other locations as well.

The majority of species are succulent shade-loving herbs or shrubs, which are easily distinguished from other Urticaceae by the combination of opposite leaves (with rare exceptions) with a single ligulate intrapetiolar stipule in each leaf axil and cymose or paniculate inflorescences (again with rare exceptions).
