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 ...

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] |
Penstemon Ambiguus
''Penstemon ambiguus'', commonly known as the bush penstemon, pink plains penstemon, or gilia beardtongue is a species of ''Penstemon'' that grows in the shortgrass prairies and deserts of the western United States and northern Mexico. This bush-like penstemon grows in sandy, loose, and creosote soils and is particularly known for the spectacular flowering show it produces, sometime seasons turning whole hillsides bright pink–white. Description ''Penstemon ambiguus'' is a perennial, somewhat bushy species with stems that are woody at their base (Glossary of plant morphology#Plant habit, suffrutescent). The stems are generally 30–40 cm tall, but will sometimes be as short as 20 cm or as tall as 60 cm, and are either smooth or somewhat rough near the base. They have paired leaves that taper from base to the tip, most often 5–30 mm long and only 0.5–1 mm wide, but occasionally as wide as 2.5 mm and as short as 3 mm or as long as 40 mm. ...

Penstemon Albomarginatus
''Penstemon albomarginatus'' is a rare species of penstemon known by the common name white-margined penstemon. It is native to the deserts of southern Nevada, western Arizona, and southern California. Description ''Penstemon albomarginatus'' is a perennial plant that grows from a relatively deep taproot that may measure long. The herbaceous stems are tall and usually have lower ends that resemble rhizomes and are buried in the sandy soil. They are hairless and somewhat waxy in texture. The leaves are cauline, attached to the stems, rather than being attached to the base of the plant. The leaves are attached by short petioles, leaf stems, or directly by the leaf base. Their surface is a glossy green and have edges without teeth, but are rough and white. Lower leaves can be reduced and resemble scales, while upper leaves may range from in length and in width. The inflorescence produces several purplish-pink tubular flowers between long surrounded at the bases by toothed, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Penstemon Albifluvis
''Penstemon albifluvis'', the White River penstemon, is a disputed species or variety of ''Penstemon'' that grows in a small area in eastern Utah and western Colorado. It grows mainly on broken shale and rock formations in desert habitats. White River penstemon is very rare. Description ''Penstemon albifluvis'' is a moderate sized herbaceous plant that usually grows between 15 and 45 centimeters tall, but may rarely be as short as 10 cm or as tall as 50 cm. Most often it has 5 to 20 stems that grow straight upwards or grow outwards a short distance before curving to grow upright, but occasionally it may have just one flowering stem. The stems sprout from a branched caudex, a persistent woody structure atop the plant's taproot. Early in development ''Penstemon albifluvis'' will have basal leaves, ones that sprout directly from the caudex, but by the time of flowering they are seldom still present. The leaves on the flowering stems are hairless with edges that are e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
