The simple leaves resemble Mango leaves, and have a scattered, alternate or subopposite arrangement. [5] They measure up to 15 by 3 cm, [2] and are paler below than above. They are glabrous and leathery in texture, and linear-oblong to narrowly elliptic in shape. [6] The leaf margins may be frilled or wavy and are tightly rolled under. [5] [7]
Leaves of most plants include a flat structure called the blade or lamina supported by a network of veins, a petiole and a leaf base; [1] but not all leaves are flat, some are cylindrical. [ citation needed ] Leaves may be simple, with a single leaf blade, or compound, with several leaflets .
habit leaves and flowers. Kunzea ericifolia, commonly known as spearwood, native tree or yellow kunzea, or as kitja boorn, poorndil or condil by the Noongar people, [1] is an erect woody evergreen shrub that is endemic to Western Australia. It has soft green linear leaves and spherical heads of usually yellow flowers in spring.
Evergreen and deciduous conifers, mostly trees and some shrubs, with heavily scented resin. Leaves are needle-shaped or linear. Pinus pinea is grown commercially for pine nuts. Many species are grown as ornamentals, especially for winter holidays. [8] Pinales
Female strobili emerge and receive pollen in the first year spring and become conelets. The conelet goes through another winter rest and, in the spring of the second year archegonia form in the conelet. Fertilization of the archegonia occurs by early summer of the second year, so the pollination-fertilization interval exceeds a year.
The berries and leaves often persist into late winter. Smilax rotundifolia is a very important food plant in the winter while there are more limited food choices. Examples of wildlife that will eat the berries and leaves in the late winter and early spring are Northern Cardinals, white throated sparrows, white tailed deer, and rabbits. [10]
The leaves appear relatively late in spring, and turn a clear pale yellow in autumn. The leaflets fold together in wet weather and at night , as some change of position at night is a habit of the entire leguminous family. Young trees are often spiny, especially on root suckers and branches near the ground; mature trees often lack spines.
Younger leaves are light green in colour and sticky to the touch, maturing to darker green leaves with a glabrous, resiny adaxial surface, and a lighter grey, densely hairy abaxial surface with a glabrescent midrib. [1] [3] [4] They are flat, fine and spreading, 2-7cm long and linear to lanceolate in shape, with pointed tips and slightly wavy ...
