Penstemon Monoensis
''Penstemon monoensis'' is a species of penstemon known by the common name Mono penstemon. It is endemic to the White and Inyo Mountains of eastern California, where it grows in scrub, woodland, and sandy washes. It is a perennial herb growing erect to about 30 centimeters tall, gray-green in color from a dense coating of light hairs. The paired leaves are lance-shaped, sometimes toothed or wavy along the edges and up to 12 centimeters long. The glandular inflorescence bears cylindrical or funnel-shaped flowers in shades of bright to deep pink, measuring around 2 centimeters in length. The mouth of the flower may have a white or pale area on the floor with a patch of hairs, and the staminode In botany, a staminode is an often rudimentary, sterile or abortive stamen, which means that it does not produce pollen.Jackson, Benjamin, Daydon; ''A Glossary of Botanic Terms with their Derivation and Accent''; Published by Gerald Duckworth & Co. ... is usually hairy.

Amos Arthur Heller
Amos Arthur Heller (March 21, 1867 – May 19, 1944) was an American botanist. Early life Heller was born in Danville, Pennsylvania, Danville, Pennsylvania. In 1892, Heller received a Bachelor of Arts degree from Franklin & Marshall College. In 1897, he received a Master's degree in Botany from Franklin & Marshall College. Career From 1896 to 1898, Heller was a professor of Botany at the University of Minnesota.

Penstemon
''Penstemon'' , the beardtongues, is a large genus of roughly 250 species of flowering plants native mostly to the Nearctic, but with a few species also found in the North American portion of the Neotropics. It is the largest genus of flowering plants endemic to North America. Formerly placed in the family Scrophulariaceae by the Cronquist system, new genetic research has placed it in the vastly expanded family Plantaginaceae. They have opposite leaves, partly tube-shaped, and two-lipped flowers and seed capsules. The most distinctive feature of the genus is the prominent staminode, an infertile stamen. The staminode takes a variety of forms in the different species; while typically a long straight filament extending to the mouth of the corolla, some are longer and extremely hairy, giving the general appearance of an open mouth with a fuzzy tongue protruding and inspiring the common name beardtongue. Most penstemons are deciduous or semi-evergreen perennials, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Mountains (California)
The White Mountains of California and Nevada are a triangular fault-block mountain range facing the Sierra Nevada across the upper Owens Valley. They extend for approximately as a greatly elevated plateau about wide on the south, narrowing to a point at the north, with elevations generally increasing south to north. The range's broad southern end is near the community of Big Pine, where Westgard Pass and Deep Springs Valley separate it from the Inyo Mountains. The narrow northern end is at Montgomery Pass, where U.S. Route 6 crosses. The Fish Lake Valley lies east of the range; the southeast part of the mountains are separated from the Silver Peak Range by block faulting across the Furnace Creek Fault Zone, forming a feeder valley to Fish Lake Valley. The range lies within the eastern section of the Inyo National Forest. Ecology Ecologically, the White Mountains are like the other ranges in the Basin and Range Province; they are dry, but the upper slopes from hold open suba ...

Inyo Mountains
The Inyo Mountains are a short mountain range east of the Sierra Nevada in eastern California in the United States. The range separates the Owens Valley to the west from Saline Valley to the east, extending for approximately south-southeast from the southern end of the White Mountains, from which they are separated by Westgard Pass, to the east of Owens Lake. Geologically, the mountains are a fault block range in the Basin and Range Province, at the western end of the Great Basin. They are considered to be among the most important and best-known Late Proterozoic to Cambrian sections in the United States. Wilderness Most of the mountain range () is designated as the Inyo Mountain Wilderness, managed by the Bureau of Land Management in the south and the United States Forest Service in the north. The USFS manages of the wilderness all within Inyo National Forest. Wildlife in the area includes the endangered Inyo Mountains salamander and the desert bighorn sheep. Plant co ...

Arroyo (creek)
An arroyo (; from Spanish arroyo , "brook"), also called a wash, is a dry stream, creek, stream bed or gulch that temporarily or seasonally fills and flows after sufficient rain. Flash floods are common in arroyos following thunderstorms. ''Wadi'' (Arabic) is used in North Africa and Western Asia for similar landforms. The desert dry wash biome is restricted to the arroyos of the southwestern United States. Arroyos provide a water source to desert animals. Types and processes Arroyos can be natural fluvial landforms or constructed flood control channels. The term usually applies to a Grade (slope), sloped or mountainous terrain in xeric and desert climates. In addition: in many rural communities arroyos are also the principal transportation routes; and in many urban communities arroyos are also parks and recreational locations, often with linear multi-use bicycle, pedestrian, and equestrian trails. Flash flooding can cause the deep arroyos or deposition of sediment on flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the ''Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the parts o ...

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 is al ...

Staminode
In botany, a staminode is an often rudimentary, sterile or abortive stamen, which means that it does not produce pollen.Jackson, Benjamin, Daydon; ''A Glossary of Botanic Terms with their Derivation and Accent''; Published by Gerald Duckworth & Co. London, 4th ed 1928 Staminodes are frequently inconspicuous and stamen-like, usually occurring at the inner whorl of the flower, but are also sometimes long enough to protrude from the corolla. Sometimes, the staminodes are modified to produce nectar, as in the Witch Hazel ''( Hamamelis)''.jin lu mei shu. Hamamelis Linnaeus, Sp. Pl. 1: 124. 1753. Flora of China 9: 32. 2003 Staminodes can be a critical characteristic for differentiating between species, for instance in the orchid genus ''Paphiopedilum'', and among the penstemons. In the case of Cannas, the petals are inconsequential and the staminodes are refined into eye-catching petal-like replacements. A spectacular example of staminode is given by ''Couroupita guianensis'', a tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
