Being one of the more visible features, leaf shape is commonly used for plant identification. Similar terms are used for other plant parts, such as petals, tepals, and bracts. Oddly pinnate, pinnatifid leaves (Coriandrum sativum, coriander or cilantro) Partial chlorosis revealing palmate venation in simple leaves of Hibiscus mutabilis
It is a plant growing readily on arable land, meadows, waste ground, roadsides, ditches, shorelines, riverbanks, woodland margins, forest clearings, and orchards. [2] [7] Seedlings can be identified by the oval leaves with red stems and rolled leaves sprouting from the center of the plant. Regrowth from the rosette usually takes place in spring.
Plant identification is a determination of the identity of an unknown plant by comparison with previously collected specimens or with the aid of books or identification manuals. The process of identification connects the specimen with a published name. Once a plant specimen has been identified, its name and properties are known.
The plant produces rosettes of leaves and an inflorescence on a long rigid scape. The leaves are extremely variable, from 10–50 cm (4– 19 + 1 ⁄ 2 in) in length [10] and 1 to 2 cm (1 ⁄ 2 to 3 ⁄ 4 in) thin to wedge-shaped like those of S. cuneata. Spongy and solid, the leaves have parallel venation meeting in the
The plant morphologist goes further, and discovers that the spines of cactus also share the same basic structure and development as leaves in other plants, and therefore cactus spines are homologous to leaves as well. This aspect of plant morphology overlaps with the study of plant evolution and paleobotany.
The leaves are alternate, trifoliate (with three leaflets), each leaflet 15–30 mm (5 ⁄ 8 – 1 + 1 ⁄ 8 in) long and 8–15 mm (3 ⁄ 8 – 5 ⁄ 8 in) broad, green with a characteristic pale crescent in the outer half of the leaf; the petiole is 1–4 cm (1 ⁄ 2 – 1 + 1 ⁄ 2 in) long, with two basal stipules that are abruptly narrowed ...
This is an incomplete list of plants with trifoliate leaves. Trifoliate leaves (also known as trifoliolate or ternate leaves) are a leaf shape characterized by a leaf divided into three leaflets. Species which are known to be trifoliate are listed here.
The leaves of the plant reach out towards the sun and for this reason the plant is sometimes called the Compass Plant. Prickly Lettuce can grow to be from two to five feet tall but should be harvested early on when it is a few inches high. The young leaves of the plant are very tender and make an excellent salad green.
