The leaves are smooth, soft, linear in shape, 10–35 mm (0.4–1 in) long, and 1 mm (0.04 in) wide. They are also rich in oil with the glands prominent. Flowers occur in white or cream-colored masses of spikes 3–5 cm (1–2 in) long over a short period, mostly spring to early summer, and give the tree an appearance of looking fluffy.
Chart illustrating leaf morphology terms. 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 leaves are simple, feather-veined, and typically linear-lanceolate. Usually they are serrate, rounded at base, acute or acuminate. The leaf petioles are short, the stipules often very conspicuous, resembling tiny, round leaves, and sometimes remaining for half the summer. On some species, however, they are small, inconspicuous, and caducous ...
Pinus, from a Latin plant name [39] [40] [41] 11 genera, [42] scattered widely in the Northern Hemisphere [43] 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 ...
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.
The leaves are thick and stiff-textured, broad, palmately lobed, superficially maple-like, the leaf blade 10–20 cm (4–8 in) long and 12–25 cm (5–10 in) broad, with a petiole 3–10 cm (1–4 in) long. The young leaves in spring are coated with minute, fine, stiff hairs at first, but these wear off and by late summer the leaves are ...
Vriesea hieroglyphica develops green leaves with irregular dark cross banding and recurved tips. The plant develops 30-40 shiny, bright green leaves measuring 3 feet (0.91 m) long and 3 inches wide. It typically blooms in spring, and can bloom repeatedly in cultivation, with branching yellow, cream, or white flowers on a tall branched spike.
The leaves emerge in mid-spring, but the flowers require day lengths of approximately 14 hours and 30 minutes to form, hence T. americana's range is limited to north of the 35th parallel. Time of flowering varies by several weeks depending on the latitude; early May in Canada and early June in the extreme southern extent.
