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 ...
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 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.
There are 27 families of flowering plants whose earliest ancestors diverged from what became the two most prominent groups of flowering plants, the eudicots and monocots. [1] [a] They are quite diverse, with woody and non-woody plants, evergreen and deciduous shrubs and trees, and plants that grow in soil, in water and on other plants.
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 divisions. There are most often about 2 millimeters of leaf tissue between the stem attachment to the leaf and the deepest point of each leaf division. [4] The edges of each leaf segment are toothed or cleft. [2]
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.
Helianthus stem in section. The cells of the vascular cambium (F) divide to form phloem on the outside, located beneath the bundle cap (E), and xylem (D) on the inside. Most of the vascular cambium is here in vascular bundles (ovals of phloem and xylem together) but it is starting to join these up as at point F between the bundles.
