Betulaceae In Flora Of North America @ Efloras.Org

Di: Ava

Species ca. 45 (16 in the flora): North America, Mexico, South America, Eurasia, Africa, Pacific Islands (New Zealand), Australia; temperate and arctic-alpine regions. The most distinctive feature of many members of Geum is their geniculate-jointed style. The style has two parts, a persistent proximal segment and a deciduous distal segment.

Corylus avellana is widely grown as an ornamental shrub in temperate North America, and it sometimes persists following cultivation, although it seldom becomes established. Corylus avellana is similar to C . americana in habit, leaves, and fruit characteristics, although it 1. Betula alleghaniensis Britton, Bull. Torrey Bot. Club. 31: 166. 1904.

Various preparations of Alnus serrulata were used medicinally by Native Americans to alleviate pain of childbirth, as a blood tonic, an emetic and purgative, for coughs and fevers, to stimulate kidneys, to bathe hives or piles, for eye troubles, indigestion, biliousness, jaundice, heart trouble, mouth soreness in babies, and toothaches, to Three subfamilies occur in North America: Pereskioideae, Opuntioideae, and Cactoideae. The fourth subfamily, Maihuenioideae, is restricted to South America (Argentina and Chile). The Cactaceae maintain an unusually complete representation of their phylogenetic history. It is a frequent component of streamside vegetation throughout the Rocky Mountains and other mountainous parts of western North America. Native Americans used alnus incana subsp. tenuifolia medicinally for pains in the lungs or hips, for scrofula, as a laxative, and as a diuretic for gonorrhea (D. E. Moerman 1986).

North American Eleocharis includes some extremely difficult species complexes that need taxonomic revision: (1) The E. palustris complex (species 1–7) is discussed under 1. E. palustris. (2) The E. tenuis complex (species 16–21) is discussed under 21. E. tenuis. (3) The four species (species 57–60) of 8c. Eleocharis subg.

Species ca. 25 (1 in the flora): mostly north temperate zone; Europe, Asia (s to India, Iran). In the flora, Carpinus consists of a single native species, C . caroliniana , which is composed of two fairly distinctive geographic races (J. J. Furlow 1987, 1987b), treated here as subspecies. 1 John J. Furlow „Betulaceae Gray in Flora of North America @ efloras.org“ eFlora. Missouri Botanical Garden, St. Louis, MO & Harvard University Herbaria, Cambridge, MA., 2003. Rhododendron, with centers of diversity in the Himalayas, New Guinea, and eastern North America, and Erica, diverse in southern Africa and Europe, are the largest genera in the family. The largest genus in the flora area is Arctostaphylos, with most species endemic to California and bordering states.

In North America, most authors have followed K. K. Mackenzie’s (1931–1935) arrangement of the genus, in which he did not recognize subgenera and instead divided the North American Carex into 71 sections. The sections were narrowly defined, for the most part consisting of groups of species that were very similar morphologically.

Maxillaria sanguinea Rolfe has reportedly become naturalized, but naturalization of the species in the flora area is dubious (C. McCartney 1997; P. M. Brown 2000). Restrepiella ophiocephala (Lindley) Garay & Dunsterville was reported to occur in North America. Apparently, it has not become naturalized in the flora area (P. M. Catling, pers. comm.). Alnus incana subsp. rugosa is an important shoreline and meadow colonizer in boreal and north temperate areas of the Canadian Shield, and a weedy successional species in damp areas along roadsides throughout its range.

The Vascular Plant families included in the Flora are listed alphabetically and by volume (taxonomically). The Bryophyte families follow that and are also listed alphabetically and partially by volume (taxonomically). Families listed in green

Carpinus caroliniana subsp. virginiana is the familiar hornbeam of the Appalachians and interior forested northeastern North America. The leaves are distinctive in that they bear scattered dark glands on the abaxial surface.

Most North American firs are major components of vegetation, especially in the boreal, Pacific Coast coniferous, and western montane coniferous forests, where they are important for watershed management. They are cut for pulpwood and lumber and, largely from plantations, for Christmas trees. Alnus oblongifolia is closely related to the Mexican and Central American A . acuminata , with which it has sometimes been confused. It is found only in scattered populations in the temperate deciduous forest vegetation zone of high mountains in the arid Southwest. Species 250–1000+ (36 in the flora): North America, Mexico, Central America, South America, Europe, Asia, Africa. Most plants referable to Hieracium are apomictic (reproducing from asexually produced seeds). Apomictic reproduction often results in perpetuation of morphologic variants at populational and regional levels.

In most instances, circumscriptions of species have turned out to be conventional. So far as practicable, recently named species from North America have been accounted for within relevant treatments herein. With 418 genera and 2413 species (Table 1), Asteraceae is, numerically, the largest family in the flora of North America north of Mexico. Alnus viridis subsp. crispa grows across much of the continent in the far North; widely disjunct populations occur in the Appalachians in Pennsylvania and on the summit of Roan Mountain on the North Carolina–Tennessee border (R. B. Clarkson 1960; E. T. Wherry 1960).

1 „Betula nigra Linnaeus in Flora of North America @ efloras.org“ eFlora. Missouri Botanical Garden, St. Louis, MO & Harvard University Herbaria, Cambridge, MA., 2003. In the flora area, var. gronovii is the third most wide­spread dodder after Cuscuta campestris and C. indecora. Rarely, some plants may have capsules apically narrowed into a neck to 1 mm, reminiscent of C. rostrata. Its progenitor, E. graminea, is introduced in the flora area and appears mainly associated with plantings in several southern states. In addition to several herbaceous European species that have become naturalized in North America, several others that have been recorded in the flora area in the past appear not to be persistent.

Infructescences erect, nearly cylindric, shattering with fruits in fall. Samaras with wings much narrower than body, broadest near center, not extended beyond body apically. Subspecies 3 (2 in the flora): subarctic and arctic of North America, Europe, and Asia. Native Americans used Ostrya virginiana medicinally to treat toothache, to bathe sore muscles, for hemorrhages from lungs, for coughs, kidney trouble, female weakness, cancer of the rectum, consumption, and flux (D. E. Moerman 1986).

The name was based on a mixture of Siberian and North American material and has never been lectotypified. Betula neoalaskana Sargent is known to hybridize with B . papyrifera Marshall, producing B . × winteri Dugle, and with B . glandulosa , producing B . × uliginosa Dugle. 3.

The Eurasian weeping birch ( Betula pendula ) is extensively cultivated throughout the temperate range of the flora, and it has been known to persist or to become locally naturalized in several areas, particularly in the Northeast. Betula glandulosa is the characteristic dwarf birch of upland habitats throughout much of the mountainous west, occurring as well in dry open areas across the north. 12.
