Micranthes Ferruginea
''Micranthes ferruginea'' is a species of flowering plant known by the common names russethair saxifrage and rusty saxifrage. It is native to western North America from Alaska and northwestern Canada to northern California to Wyoming Wyoming () is a state in the Mountain West subregion of the Western United States. It is bordered by Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the sou ..., where it can be found in moist, rocky habitat in mountainous areas. It is a perennial herb growing from a caudex and rhizome system and producing a basal rosette of leaves. Each leaf is up to 6 centimeters long, thick and fleshy with large teeth along the edges. The inflorescence arises on a slender, hairy peduncle (botany), peduncle up to 40 centimeters tall. Thin branches bear flowers and reproductive bulbils. Each flower has spade-shaped white petals, the upper ones dotted with gold. External links ...

Robert Graham (botanist)
Robert Graham (3 December 1786 – 7 August 1845) was a Scottish physician and botanist. Life Graham was born in Stirling the son of Dr Robert Graham, physician. After studying at Stirling Grammar School he continued first to the University of Glasgow and then to the University of Edinburgh where he graduated around 1806, and completed his MD in 1808. He trained further at St Bartholomew's Hospital, London, where he qualified as a surgeon. He then returned to Scotland to practice at Glasgow Royal Infirmary 1812-3 and 1816–19. In 1816 he began lecturing in botany at the University of Glasgow, taking over from Thomas Brown of Lanfine and Waterhaughs following his resignation. He was a major figure in the creation of Glasgow Botanic Gardens, and was the inaugural Chair of Botany at the Glasgow in 1818. In 1820 he moved to Edinburgh to take up the position of Professor of Botany and Medicine at the University of Edinburgh, a role he continued until 1845. He was also physi ...

Bulb
In botany, a bulb is structurally a short stem with fleshy leaves or leaf basesBell, A.D. 1997. ''Plant form: an illustrated guide to flowering plant morphology''. Oxford University Press, Oxford, U.K. that function as food storage organs during dormancy. (In gardening, plants with other kinds of storage organ are also called " ornamental bulbous plants" or just "bulbs".) Description The bulb's leaf bases, also known as scales, generally do not support leaves, but contain food reserves to enable the plant to survive adverse conditions. At the center of the bulb is a vegetative growing point or an unexpanded flowering shoot. The base is formed by a reduced stem, and plant growth occurs from this basal plate. Roots emerge from the underside of the base, and new stems and leaves from the upper side. Tunicate bulbs have dry, membranous outer scales that protect the continuous lamina of fleshy scales. Species in the genera ''Allium'', '' Hippeastrum'', ''Narcissus'', and '' ...

Flora Of The Cascade Range
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurma ...

Micranthes
''Micranthes'' is a genus of flowering plants in the saxifrage family. It was formerly included within the genus '' Saxifraga'' until recent DNA evidence showed the members of what is now ''Micranthes'' are more closely related to ''Boykinia'' and ''Heuchera'' than to other members of the genus ''Saxifraga''. All members of this genus are herbaceous, with prominent basal leaves. They are found in north-temperate, arctic, and alpine regions. Species The following species are recognised in the genus ''Micranthes'': *''Micranthes apetala'' *''Micranthes aprica'' – Sierra saxifrage *''Micranthes astilboides'' *''Micranthes atrata'' *''Micranthes brachypetala'' *''Micranthes bryophora'' *''Micranthes californica'' *''Micranthes calycina'' *''Micranthes careyana'' *''Micranthes caroliniana'' *''Micranthes cismagadanica'' *''Micranthes clavistaminea'' *''Micranthes clusii'' *''Micranthes davidii'' *''Micranthes davurica'' *''Micranthes divaricata'' *''Micranthes dung ...

Peduncle (botany)
In botany, a peduncle is a stalk supporting an inflorescence or a solitary flower, or, after fecundation, an infructescence or a solitary fruit. The peduncle sometimes has bracts (a type of cataphylls) at nodes. The main axis of an inflorescence above the peduncle is the rachis. There are no flowers on the peduncle but there are flowers on the rachis. When a peduncle arises from the ground level, either from a compressed aerial stem or from a subterranean stem (rhizome, tuber, bulb, corm), with few or no bracts except the part near the rachis or receptacle, it is referred to as a scape. The acorns of the pedunculate oak ''Quercus robur'', commonly known as common oak, pedunculate oak, European oak or English oak, is a species of flowering plant in the beech and oak family, Fagaceae. It is a large tree, native to most of Europe west of the Caucasus. It is wid ... are borne on a long peduncle, hence the name of the tree. See also * Pedicel (botany) * Scape (botany) ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ...

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 ...

Rhizome
In botany and dendrology, a rhizome (; , ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs underground horizontally. A stolon is similar to a rhizome, but a stolon sprouts from an existing stem, has long internodes, and generates new shoots at the end, such as in the strawberry plant. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes appli ...
