Potentilla Verna In Flora Of North America @ Efloras.Org

Di: Ava

Draba verna represents a highly variable and taxonomically difficult complex within which species, subspecies, varieties, and forms have been named (O. E. Schulz 1927); only those synonyms The earliest North American collection of Potentilla recta seen by the authors was gathered by C. W. Short as a weed in a garden in Montreal in 1852 (MO). It was encountered initially as a Subspecies 2 (2 in the flora): North America, Eurasia. The name Potentilla arenosa is now used for most arctic and subarctic plants previously treated as P. hookeriana or P. nivea subsp.

Potentilla vahliana is treated here as a geographically restricted species, most probably from cross (es) between P. nivea in the narrow sense (probably the Atlantic race, often 2 n = 70)

Potentilla norvegica Calflora

Variety concinna is the compact phase of Potentilla concinna with strictly palmate, short-toothed leaves that are often prominently bicolored. The variety occurs primarily in vernally wet

Flowering May–Sep. Rocky slopes, open ground, in pine-oak and mixed conifer woodlands; of conservation concern; 1800–3200 m; Ariz. Potentilla albiflora grows on the Pinaleño (Graham) Potentilla anglica probably was introduced even in Newfoundland (A. Kurtto et al. in J. Jalas et al. 1972+, vol. 13), contrary to the view expressed by M. L. Fernald (1950). The name Potentilla The distinction between Potentilla simplex and P. canadensis is subtle, and the former is often misidentified as the latter; additional features to distinguish the two species are provided by M.

Species 25–30 (15 in the flora): North America, nw Mexico, Eurasia; mostly temperate areas. The convergence of morphologic (J. Soják 1985 [1989]) and molecular (T. Eriksson et al. 1998; M.

Dasiphora fruticosa is circumboreal, encompassing significant variation, some of which has often been given taxonomic recognition on the basis of ploidy level, sexuality, vestiture, leaflet 10. Potentilla supina Linnaeus, Sp. Pl. 1: 497. 1753. Subspecies 7 (1 in the flora): North America, Mexico, Eurasia, Africa; introduced in Australia. The status of Potentilla supina in North Some of these states consider it a species of conservation concern (as Potentilla arguta, tall cinquefoil), and the sparsely hairy nature of some of these populations suggests that further

Subspecies 3 (2 in the flora): North America, n Eurasia; circumpolar. Southern arctic and subarctic plants differ from the northern arctic ones in presumably independent features. Potentilla subgorodkovii constitutes about half of what previously has been considered P. uniflora in Alaska and Yukon and is the only such entity fully confirmed south of northern British 54a. Potentilla subviscosa Greene var. subviscosa Stems 0.2–1 (–1.5) dm. Basal leaves often notably seasonally dimorphic, (1–)2–6 (–18 in late-season) cm; petiole (0.5–)1–4 (–10 in late

Potentilla hippiana is most common and distinctive in the Colorado Plateau and southern Rocky Mountains, with outliers in the mountains of Arizona, Nevada, and New Mexico.

Flowering late spring–summer. Leymus-Potentilla sand dunes, coastal gravel bars, beach ridges; 0–10 m; Alaska; e Asia (Russian Far East). Recent collections of Potentilla fragiformis in Although included here, Potentilla erecta is questionably extant as a naturalized species in North America and is not currently known from Newfoundland where historically reported. It is a Flowering summer. Herb meadows, alluvial meadows and flats, open shrub thickets, Salix – Dryas tundra; 10–600 m; Greenland; Alaska; Eurasia. The occurrences of Potentilla stipularis in

The optimum taxonomic disposition of var. pseudocalabra, and whether any North American plants are properly included, remains to be determined. Potentilla argentea has been reported

Potentilla crinita occurs mainly in the upper foothills and mountains from southern Nevada to south-central Utah, northern Arizona, and northwestern New Mexico and is disjunct to Molecular evidence (B. Eriksen and M. H. Töpel 2006) indicates that populations of Potentilla nivea in the Atlantic regions, including Greenland and eastern Canada, differ from those in the 1 „Potentilla verna Linnaeus in Flora of North America @ efloras.org“ eFlora.
