[citation needed] Leaves may be simple, with a single leaf blade, or compound, with several leaflets. Compound leaves may be pinnate with pinnae (leaflets) on both sides of a rachis (axis), or may be palmate with multiple leaflets arising from a single point. [1] Leaf structure is described by several terms that include:
A bundle or structure of stamens forming one unit in an adelphous flower; for example, the stamen tube around the pistil of Hibiscus. adelphous Having organs, particularly filament s such as stamen s, connected into one or more adelphiae, whether in the form of bunches or tubes, such as is commonly seen in families such as Malvaceae. Usage of ...
The leaves are simple, pinnate, or bipinnate, and arranged in opposite pairs. The flowers are produced in a capitulum with a ring of broad ray florets and a center of disc florets; flower color varies noticeably between the different species.
The two main classes of compound leaf morphology are palmate and pinnate. For example, a hemp plant has palmate compound leaves, whereas some species of Acacia have pinnate leaves. The ultimate free division (or leaflet) of a compound leaf, or a pinnate subdivision of a multipinnate leaf is called a pinnule or pinnula.
The leaves are arranged alternately along the stems and are simple or pinnate. The flowers have three to seven sepals but that fall of as the flowers mature, but no petals. There are six to sixteen stamens (except in female flowers), the filaments shorter than the anthers, the style is threadlike and the ovary in female flowers has two to six ...
Bract – the leaf- or scale-like appendages that are located just below a flower, a flower stalk, or an inflorescence; they usually are reduced in size and sometimes showily or brightly colored. Calyx – the whorl of sepals at the base of a flower, the outer whorl of the perianth.
An evergreen woody vine. Stems with swollen nodes. Leaves opposite, stalked, simple, pinnately veined, margin entire. Flowers unisexual, borne in whorled, spike-like cones, arranged in lax, cymes. Male spikes have collars closely arranged and ± hiding axis (less often somewhat laxly arranged), each collar with 20–80 flowers, often also with ...
This is a list of plants organized by their common names. However, the common names of plants often vary from region to region, which is why most plant encyclopedias refer to plants using their scientific names , in other words using binomials or "Latin" names.
