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.
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]
Chart illustrating 61 morphological terms describing leaf shape, margins and venation. While Diliff's mega-panoramas are a hard act to follow, I thought I would throw the metaphorical hat into the ring with this illustration. I created it with the desire to make a richly encyclopedic image/poster with lots of information about leaf morphology.
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.
Leaf vegetables, also called leafy greens, pot herbs, vegetable greens, or simply greens, are plant leaves eaten as a vegetable, sometimes accompanied by tender petioles and shoots. Leaf vegetables eaten raw in a salad can be called salad greens .
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.
Duration of leaves: Deciduous – leaves are shed after the growing season. Evergreen – leaves are retained throughout the year, sometimes for several years. Fugacious – lasting for a short time: soon falling away from the parent plant. Marcescent – dead leaves, calyx, or petals are persistent and retained. Persistent – see Marcescence ...
Articles relating to leaf vegetables, plant leaves eaten as a vegetable, sometimes accompanied by tender petioles and shoots. Although they come from a very wide variety of plants, most share a great deal with other leaf vegetables in nutrition and cooking methods.
