Phytomorphology is the study of the physical form and external structure of plants. [1] This is usually considered distinct from plant anatomy, [1] which is the study of the internal structure of plants, especially at the microscopic level. [2] Plant morphology is useful in the visual identification of plants.
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 ...
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.
Sempervivum (/ s ɛ m p ə ˈ v aɪ v əm / [1] [2]) is a genus of about 40 species of flowering plants in the family Crassulaceae, commonly known as houseleeks.Other common names include liveforever (the source of the taxonomical designation Sempervivum, literally "always/forever alive") and hen and chicks, a name shared with plants of other genera as well.
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.
