Ribes Ciliatum
''Ribes'' is a genus of about 200 known species of flowering plants, most of them native to the temperate regions of the Northern Hemisphere. The various species are known as currants or Ribes uva-crispa, gooseberries, and some are Horticulture, cultivated for their edible fruit or as ornamental plants. ''Ribes'' is the only genus in the family Grossulariaceae. Description ''Ribes'' species are medium shrublike plants with marked diversity in strikingly diverse flowers and fruit. They have either palmately lobed or compound leaves, and some have thorns. The sepals of the flowers are larger than the petals, and fuse into a tube or saucer shape. The Ovary (botany), ovary is inferior, maturing into a berry with many seeds. Taxonomy ''Ribes'' is the single genus in the Saxifragales Family (biology), family Grossulariaceae. Although once included in the broader Circumscription (taxonomy), circumscription of Saxifragaceae ''sensu, sensu lato'', it is now positioned as a sister group ...

Ribes Divaricatum
''Ribes divaricatum'' is a species in the genus ''Ribes'' found in the forests, woodlands, and coastal scrub of western North America from British Columbia to California. The three accepted varieties have various common names which include the word "gooseberry". Other common names include coast black gooseberry, wild gooseberry, Worcesterberry, or spreading-branched gooseberry. Description ''Ribes divaricatum'' is a shrub sometimes reaching in height with woody branches with one to three thick brown spines at leaf nodes. The leaves are generally palmate in shape and edged with teeth. The blades are up to long and borne on petioles. The inflorescence is a small cluster of hanging flowers, each with reflexed purple-tinted green sepals and smaller, white to red petals encircling long, protruding stamens. The fruit is a sweet-tasting berry up to wide which is black when ripe. It is similar to ''Ribes lacustre'' and '' R. lobbii'', but the former has smaller, reddish to mar ...

Saxifragaceae
Saxifragaceae is a family of herbaceous perennial flowering plants, within the core eudicot order Saxifragales. The taxonomy of the family has been greatly revised and the scope much reduced in the era of molecular phylogenetic analysis. The family is divided into ten clades, with about 640 known species in about 35 accepted genera. About half of these consist of a single species, but about 400 of the species are in the type genus '' Saxifraga''. The family is predominantly distributed in the northern hemisphere, but also in the Andes in South America. Description Species are herbaceous perennials (rarely annual or biennial), sometimes succulent or xerophytic, often with perennating rhizomes. The leaves are usually basally aggregated in alternate rosettes, sometimes on inflorescence stems. They are usually simple, rarely pinnately or palmately compound. Their margins may be entire, deeply lobed, cleft, crenate or dentate and petiolate with stipules. The infloresc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glabrousness (botany)
Glabrousness (from the Latin '' glaber'' meaning "bald", "hairless", "shaved", "smooth") is the technical term for a lack of hair, down, setae, trichomes or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabres ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between org ...

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have t ...
