Penstemon Utahensis
''Penstemon utahensis'' is a species of penstemon known by the common names Utah beardtongue and Utah penstemon. It is native to the southwestern United States, where it grows in scrub, woodland, and canyons. It is a perennial plant, perennial herbaceous plant, herb growing erect to a maximum height near half a meter. The thick leaves are located around the base of the plant and in opposite pairs along the stem. The upper leaves are lance-shaped and often folded lengthwise, measuring up to 5.5 centimeters long. The showy inflorescence bears many bright red-pink flowers up to 2.5 centimeters in length. They are cylindrical, tubular, or funnel-shaped with wide, lobed mouths, and mostly hairless to slightly hairy and glandular.

Alice Eastwood
__NOTOC__ Alice Eastwood (January 19, 1859 – October 30, 1953) was a Canadian American botanist. She is credited with building the botanical collection at the California Academy of Sciences in San Francisco. She published over 310 scientific articles and authored 395 land plant species names, the fourth-highest number of such names authored by any female scientist. There are seventeen currently recognized species named for her, as well as the genera '' Eastwoodia'' and ''Aliciella''. Biography Alice Eastwood was born on January 19, 1859, in Toronto, Canada West, to Colin Skinner Eastwood and Eliza Jane Gowdey Eastwood. Her father worked at the Toronto Asylum for the Insane. When she was six her mother died; Eastwood and her siblings were cared for by various relatives, and for a time, Alice and her sister were placed at the Oshawa Convent in Toronto. In 1873, Eastwood and her siblings were reunited with their father and moved to Denver, Colorado. In 1879, she graduated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penstemon
''Penstemon'' , the beardtongues, is a large genus of roughly 280 species of flowering plants native to North America from northern Canada to Central America. It is the largest genus of flowering plants endemic to North America. As well as being the scientific name, penstemon is also widely used as a common name for all ''Penstemon'' species alongside beardtongues. Formerly placed in the family Scrophulariaceae by the Cronquist system, new genetic research has placed it in the vastly expanded family Plantaginaceae. The total number of species is uncertain due to on going research into if some of the named species are actually subspecies or misidentifications of already identified species. Description 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 it is typically a long stra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial Plant
In horticulture, the term perennial (''wikt:per-#Prefix, per-'' + ''wikt:-ennial#Suffix, -ennial'', "through the year") is used to differentiate a plant from shorter-lived annual plant, annuals and biennial plant, biennials. It has thus been defined as a plant that lives more than 2 years. The term is also loosely used to distinguish plants with little or no woody growth (secondary growth in Tree girth measurement, girth) from trees and shrubs, which are also technically ''perennials''. Notably, it is estimated that 94% of plant species fall under the category of perennials, underscoring the prevalence of plants with lifespans exceeding two years in the botanical world. Perennials (especially small flowering plants) that 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 plant, herbaceous perennials. However, depending on the rigours of the loca ... [...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, th ...

Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), 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. General characteristics Inflorescences are described by many different charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
