English: Cross section of the stem of a herbaceous dicot (garlic mustard Alliaria petiolata), showing the vascular bundles at left (with purple xylem cells and dusky grey phloem cells) that fringe the cortex, and (parenchyma, or thin-walled) pith cells to the right (turquoise blue), which are available as storage tissue for water, carbohydrates and other nutrients, which will sustain future ...
The basal eudicots are a group of 13 related families of flowering plants in four orders: Buxales, Proteales, Ranunculales and Trochodendrales. [1] [a] Like the core eudicots (the rest of the eudicots), they have pollen grains with three colpi (grooves) or other derived structures, [4] and usually have flowers with four or five petals (sometimes multiples of four or five, sometimes reduced or ...
A forb or phorb is a herbaceous flowering plant that is not a graminoid (grass, sedge, or rush). The term is used in botany and in vegetation ecology especially in relation to grasslands [1] and understory. [2] Typically, these are eudicots without woody stems.
Basal eudicot is an informal name for a paraphyletic group. The core eudicots are a monophyletic group. [11] A 2010 study suggested the core eudicots can be divided into two clades, Gunnerales and a clade called Pentapetalae, comprising all the remaining core eudicots. [12] The Pentapetalae can be then divided into three clades: [citation needed]
A caudex (pl.: caudices) of a plant is a stem, [1] but the term is also used to mean a rootstock [2] and particularly a basal stem structure from which new growth arises. [ 3 ] In the strict sense of the term, meaning a stem, "caudex" is most often used with plants that have a different stem morphology from the typical angiosperm dicotyledon ...
Floral diagram. Adonis annua. Ranunculaceae are mostly herbaceous annuals or perennials, but some are woody climbers (such as Clematis) [3] or shrubs (e.g. Xanthorhiza). Most members of the family have bisexual flowers which can be showy or inconspicuous. Flowers are solitary, but are also found aggregated in cymes, panicles, or spikes.
Aconitum columbianum is an herbaceous perennial that grows from a large tuber-like root with a spindle shape. [2] [3] The stems can be from 20-300 centimeters tall and be either erect or trailing. [4] Leaves. The leaves that are attached to the stems have as many as 7 deep divisions almost reaching the base of the leaf, but most often 3–5 ...
In botany, a cortex is an outer layer of a stem or root in a vascular plant, lying below the epidermis but outside of the vascular bundles. [1] The cortex is composed mostly of large thin-walled parenchyma cells of the ground tissue system and shows little to no structural differentiation. [ 2 ]
