Jepsonia Parryi
''Jepsonia parryi'' is an uncommon species of flowering plant in the saxifrage family known by the common names coast jepsonia and Parry's jepsonia. It is a small geophytic plant that flowers briefly during fall, and often only has a single leaf that may appear above the ground after or during flowering. It is native to the coast and inland hills chaparral of southern California and Baja California. Description This plant is a small perennial herb emerging from an enlarged underground stem, referred to as a caudex. The caudex is unbranched, shaped ovoid or rarely spherical. Typically, only one leaf is produced per plant on average, but if this leaf is injured another one may develop to replace it. The leaf is round or kidney-shaped and has a ruffled, lobed edge. Flowering is from October to February, producing a naked brown peduncle that is generally 3 to 28 cm tall, which holds a small inflorescence of fewer than four flowers. The tiny flower has tan to purplish-veined peta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jepsonia Malvifolia
''Jepsonia malvifolia'' is an uncommon species of flowering plant in the saxifrage family known by the common name island jepsonia or island button-saxifrage. It is found only on the Channel Islands of California and Guadalupe Island off Baja California. It grows in exposed rock and clay soils on the chaparral and scrub slopes of the islands. This is a small perennial herb growing up to tall. It produces two or three leaves from a flat caudex. The green leaves are round or kidney-shaped and edged with ruffled lobes. The plant flowers in fall, producing an inflorescence on a tall peduncle Peduncle may refer to: *Peduncle (botany), a stalk supporting an inflorescence, which is the part of the shoot of seed plants where flowers are formed *Peduncle (anatomy), a stem, through which a mass of tissue is attached to a body **Peduncle (art .... The tiny flowers have red-veined white, yellowish, or pinkish petals. The fruit is a tan-striped greenish capsule. Its chromosome number is 2n=1 ...

Jepsonia Heterandra
''Jepsonia heterandra'' is an uncommon species of flowering plant in the saxifrage family known by the common name foothill jepsonia. It is endemic to the foothills of the central section of the Sierra Nevada in California, where it grows in woodland and forest. This is a small perennial plant growing two or three leaves from a branching caudex. The flat, green leaves are round or kidney-shaped with frilly lobes along the edges. Flowering occurs in fall. The plant produces an inflorescence of several pinkish flowers on a tall peduncle Peduncle may refer to: *Peduncle (botany), a stalk supporting an inflorescence, which is the part of the shoot of seed plants where flowers are formed *Peduncle (anatomy), a stem, through which a mass of tissue is attached to a body **Peduncle (art ....

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] |
John Kunkel Small
John Kunkel Small (January 31, 1869 – January 20, 1938) was an American botanist. Born on January 31, 1869, in Harrisburg Pennsylvania, Kunkel studied botany at Franklin & Marshall College and Columbia University. He was the first Curator of Museums at The New York Botanical Garden, a post in which he served from 1898 until 1906. From 1906 to 1934 he was Head Curator and then from 1934 until his death he was Chief Research Associate and Curator. Small's doctoral dissertation, published as ''Flora of the Southeastern United States Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. Et ...'' in 1903, anrevised in 1913and 1933, remains the best floristic reference for much of the South. Assisted by the patronage of Charles Deering, Small traveled extensively around Florida recording p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corm
A corm, bulbo-tuber, or bulbotuber is a short, vertical, swollen underground plant stem that serves as a storage organ that some plants use to survive winter or other adverse conditions such as summer drought and heat ( perennation). The word ''cormous'' usually means plants that grow from corms, parallel to the terms ''tuberous'' and ''bulbous'' to describe plants growing from tubers and bulbs. Structure A corm consists of one or more internodes with at least one growing point, generally with protective leaves modified into skins or tunics. The tunic of a corm forms from dead petiole sheaths—remnants of leaves produced in previous years. They act as a covering, protecting the corm from insects, digging animals, flooding, and water loss. The tunics of some species are thin, dry, and papery, at least in young plants, however, in some families, such as ''Iridaceae'', the tunic of a mature corm can be formidable protection. For example, some of the larger species of '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caudex
A caudex (plural: caudices) of a plant is a Plant stem, stem, but the term is also used to mean a rootstock and particularly a basal stem structure from which new growth arises.pages 456 and 695 In the strict sense of the term, meaning a stem, "caudex" is most often used with plants that have a different stem Morphology (biology), morphology from the typical flowering plant, angiosperm dicotyledon stem: examples of this include Arecaceae, palms, ferns, and cycads. The related term caudiciform, literally meaning stem-like, is sometimes used to mean pachycaul, thick-stemmed. Etymology The term is from the Latin language, Latin ''caudex'', a noun meaning "tree trunk".

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk ...
