The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1] The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or ...
This is an incomplete list of plants with trifoliate leaves. Trifoliate leaves ... [2] Aspalathus spp. [1] B
A plant that loses all of its leaves only briefly before growing new ones, so that it is leafless for only a short time, e.g. approximately two weeks. bristle A straight, stiff hair (smooth or with minute teeth); the upper part of an awn (when the latter is bent and has a lower, stouter, and usually twisted part, called the column ).
The leaves and stems of the plant can be cooked as a leaf vegetable if gathered before the fruits harden. [9] However, the numerous small hooks which cover the plant and give it its clinging nature can make it less palatable if eaten raw. [27] [28] Cleavers are in the same family as coffee.
Alternate distichous leaves will have an angle of 1/2 of a full rotation. In beech and hazel the angle is 1/3, [citation needed] in oak and apricot it is 2/5, in sunflowers, poplar, and pear, it is 3/8, and in willow and almond the angle is 5/13. [6] The numerator and denominator normally consist of a Fibonacci number and its second successor ...
Leaf of Pyrus calleryana with petiole. In botany, the petiole (/ ˈ p iː t i. oʊ l /) is the stalk that attaches the leaf blade to the stem. [1]: 87 [2]: 171 It is able to twist the leaf to face the sun, producing a characteristic foliage arrangement (spacing of blades), and also optimizing its exposure to sunlight.
The spadix is around 2/3 as long as the spathe; with A. maculatum it is only 1/2 as long. The spadix of A. cylindraceum is never yellow, which it can be with A. maculatum. A. cylindraceum never has spotted leaves (except when hybridizing with A. maculatum). Note that A. maculatum, despite the name, does not always have spotted leaves (e.g.
A broad-leaved, broad-leaf, or broadleaf tree is any tree within the diverse botanical group of angiosperms that has flat leaves and produces seeds inside of fruits. It is one of two general types of trees, the other being a conifer, a tree with needle-like or scale-like leaves and seeds borne in woody cones. [1]
