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] |
List Of Penstemon Species
Species in the genus ''Penstemon'' are commonly called penstemons or beardtongues in English, and they will often have a common name based on either. As the subgenuses have some taxonomic uncertainty, the species are arranged alphabetically by name in the lists. there are species and seven natural Hybrid (biology), hybrids, according to Plants of the World Online (POWO). The database World Flora Online (WFO) regards all the species listed by POWO as valid, but additionally lists two natural hybrids as species and four additional species as valid. ''Penstemon'' species These species of Penstemon are considered valid by both World Flora Online (WFO) and Plants of the World Online (POWO), with the exception of ''Penstemon grandiflorus''. In both POWO and WFO, it is regarded as a synonym of ''Penstemon bradburyi''. However, ''P. grandiflorus'' continues to be widely used as the correct species name in North America, including by the Flora of North America and the USDA Natura ...

Pennellianthus
''Pennellianthus'' is a monotypic genus of flowering plants belonging to the family Plantaginaceae. It only contains one known species, ''Pennellianthus frutescens'' (Lamb.) Crosswh. The genus is within the Tribe Cheloneae along with ''Penstemon'', from which ''Pennellianthus'' was separated from. Its native range is Russian Far East (within the regions of Kamchatka, Khabarovsk, the Kuril Islands, Magadan, Sakhalin) and also Japan. The genus name of ''Pennellia'' is in honour of Francis W. Pennell (1886–1952), an American botanist best known for his studies of the '' Scrophulariaceae''. The Latin specific epithet In Taxonomy (biology), taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin gramm ... of ''frutescens'' means shrubby (referring to the habit of the plant).

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 ''C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cheloneae
Plantaginaceae, the plantain family or veronica family, is a large, diverse family of flowering plants in the order Lamiales that includes common flowers such as snapdragon and foxglove. It is unrelated to the banana-like fruit also called "plantain". In older classifications, Plantaginaceae was the only family of the order Plantaginales, but numerous phylogenetic studies, summarized by the Angiosperm Phylogeny Group, have demonstrated that this taxon should be included within Lamiales. Overview The plantain family as traditionally circumscribed consisted of only three genera: '' Bougueria'', '' Littorella'', and ''Plantago''. However phylogenetic research has indicated that Plantaginaceae ''sensu stricto'' (in the strict sense) were nested within Scrophulariaceae (but forming a group that did not include the type genus of that family, '' Scrophularia''). Although Veronicaceae (1782) is the oldest family name for this group, Plantaginaceae (1789) is a conserved name under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scrophulariaceae
The Scrophulariaceae are a family of flowering plants, commonly known as the figwort family. The plants are annual and perennial herbs, as well as shrubs. Flowers have bilateral (zygomorphic) or rarely radial (actinomorphic) symmetry. The Scrophulariaceae have a cosmopolitan distribution, with the majority found in temperate areas, including tropical mountains. The family name is based on the name of the included genus ''Scrophularia'' L. Taxonomy In the past, it was treated as including about 275 genera and over 5,000 species, but its circumscription has been radically altered since numerous molecular phylogenies have shown the traditional broad circumscription to be grossly polyphyletic. Many genera have recently been transferred to other families within the Lamiales, notably Plantaginaceae and Orobanchaceae, but also several new families. - on linhere/ref> Several families of the Lamiales have had their circumscriptions enlarged to accommodate genera transferred from ...

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] |
Nectar Guide
Nectar guides are markings or patterns seen in flowers of some angiosperm species, that guide pollinators to their Pollination syndrome, rewards. These markings may appear as lines, spots, or "blotches". Such patterns are also known as "pollen guides" and "honey guides", though some authorities argue for the abandonment of such terms in favour of ''floral guides'' (see, for example, Dinkel & Lunau). Pollination Nectar guides serve as an Signalling theory, interspecific signal that the flower contains a reward. Rewards commonly take the form of nectar (plant), nectar, pollen, or both; however, plants may also produce oil, resins, Floral scent, scents, or waxes. Pollinator visitation can select for various floral traits, including nectar guides, through a process called pollinator-mediated selection. For example, nectar guides are thought to increase pollinator foraging efficiency by reducing handling time. These guides may also decrease nectar robbing, which leads more pollen to ...
