Flora of north america.
Of the angiospermous trees of North America, Platanus occidentalis is one of the tallest (to 50+m) and reaches the greatest trunk diameter (to 4+m). Trees with smaller and broader-than-long leaf blades, with lobes mostly entire, have been called P. occidentalis var. glabrata (Fernald) Sargent, especially in the western range of the species from ...
Genera 184, species ca. 2500 (19 genera, 29 species in the flora): worldwide, especially abundant in Central America, South America, se Asia. Although palms appeared in various taxonomic schemes since the time of Linnaeus, the first attempt at a modern phylogenetic classification of the palms was published by H. E. Moore Jr. (1973).The Calymperaceae are defined by clasping leaf bases with cancellinae, absence of stem central strand, usually thickened and toothed leaf margins, mainly tropical-subtropical range, corticolous habitat, and common production of uniseriate leaf-tip gemmae. Plants of the family are specialized for water capture and retention by their sheathing ...An atlas and annotated list of the vascular plants of Arkansas, 2d ed.. TEX.

Genera 15, species ca. 500 (12 genera, 93 species in the flora). Bryaceae is a large family of acrocarpous mosses with a global distribution. Many species are adapted to disturbed soil and somewhat weedy. Species exhibit a remarkable array of specialized asexual reproductive structures, perhaps more than in any other bryophyte family.

Species ca. 50 (2 in the flora). Although the taxonomy of Rhinanthus in the Old World is complex, the taxa found in North America are reasonably distinct. The subapical teeth on the adaxial corolla lip have been described as galea or nipples; the term teeth is used in this account.Family List Total: 31 records Taxon Id: Name # Lower Taxa : 10042: Anemiaceae : 1: 10072: Aspleniaceae : 1: 10085: AzollaceaeDiscussion. Varieties 2 (2 in the flora). The infraspecific taxonomy of Phytolacca americana has been disputed since J. K. Small (1905) recognized P. rigida as distinct from P. americana on the basis of its "permanently erect panicles" [sic] and "pedicels…much shorter than the diameter of the berries." J. W. Hardin (1964b) separated P. rigida from P. americana by the length of the ...Etymology: Classical Latin for the English oak, Quercus robur, from some central European language.

Leaves: stipules deciduous and inconspicuous (except in Quercus ...
Species ca. 12 (8 in the flora): North America (including Mexico), South America, Europe, Asia, Africa. Chromosome number and habit traditionally have been used to separate Fallopia (x = 10; climbing or sprawling, fibrous-rooted annuals and perennials) from Reynoutria (x = 11; erect, rhizomatous perennials).

It treats 923 species classified among 125 genera in 11 families; the larger families covered in Volume 7 include Brassicaceae (Mustard family), Cleomaceae (Spiderflower family), and Salicaceae (Willow family).Curtopogon dichotomus (Michx.) P.Beauv. Aristida dichotoma, known as churchmouse threeawn, [2] fork-tip three-awn, [3] pigbutt three-awn, [4] and poverty grass, [5] is a species of grass from eastern North America. [1] It is native to the Eastern and Midwestern United States and Ontario, Canada. It has been introduced in California. [1]In part on this basis, H. A. Gleason and A. Cronquist (1991, 2004) included T. spectabile Dahlstedt (Bot. Not. 1905: 159) in the northeastern North American flora, from southern Ontario and New York state. Apart from an old specimen from New York state, I have been unable to locate vouchers of the species for New York or Ontario.
Statements of economic uses supplied and documented by the author(s), Native American medicinal plants based on D. E. Moerman (1986), and weed status determined in consultation with weed specialist Robert H. Callihan are given in order to make this information more easily available to users of the Flora of North America North of Mexico.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.Trees, winter-deciduous. Terminal buds present, long, tapered in maturity, all scales imbricate. Leaves: stipules prominent on new growth, soon deciduous. Leaf-blade thin, secondary-veins unbranched, ± parallel, extending to margin, each vein ending in acute or obscure tooth.Inflorescences unisexual, axillary in new growth leaves; staminate inflorescence lax, loosely capitate cluster of ...Flora of North America : Taxon Id: Name # Lower Taxa : Volume: 10931: Urticaceae: eFlora Home | People Search | Help | ActKey | Hu Cards | Glossary |Species 18 (11 in the flora).

Trillium is traditionally divided into two subgenera, which overlap in some characters. Botanists consider subg. Trillium to be the more primitive group, because the genera considered closest to Trillium all have pedicellate flowers, as does subg.
Discussion. Species 60(-2000) (15 in the flora). The type of the genus, Taraxacum officinale, is conserved.This name is linked to the (very general) description of Leontodon taraxacum Linnaeus. A. J. Richards (1985) typified T. officinale, via L. taraxacum, on a specimen that is apparently referable to T. campylodes Haglund, a microspecies of sect. Crocea restricted to Lapland, which thus ...Welcome.

Click on a volume # for individual families, genera, contributors names and email addresses, and if the manuscript has been received.The erect habit, bright green and usually glabrous foliage, and dark involucres of Mirabilis melanotricha are distinctive in combination. Once collected and pressed, M. melanotricha becomes yet another "difficult" Mirabilis. In 1911, P. C. Standley noted that this species (as Allionia melanotricha) was one of the most variable in the genus ...Genera 7, species 59 (2 genera, 17 species in the flora). The fruit in Juglandaceae superficially resembles a drupe, with a hard "stone" surrounded by a soft, often fleshy husk. The husk, however, is not part of the fruit wall (it develops from the involucre and calyx), and the fruit is actually a nut (T. S. Elias 1972; W. E. Manning 1978).Plants annual, biennial, or perennial; mericarps: dehiscent part 10-75% of height, indehiscent part ± equaling to usually wider than dehiscent part > 2: 1 Plants perennial; mericarps: dehiscent part 50-85% of height, indehiscent part usually not notably wider than dehiscent part > 9: 2 Leaf blade surfaces silvery stellate-lepidote.Discussion. Species ca. 100 (77 in the flora). Solidago is found primarily in North America with some South American and Eurasian species (8 in Mexico, 4 in South America, 6-10 in Europe and Asia).Discussion. The taxonomy of Viola is often considered difficult partly because of hybridization; more than 100 named hybrids occur in the flora area. Hybrids among the blue-flowered, acaulescent species in eastern North America and among other species are well known (E. Brainerd 1924; N. H. Russell and M. Cooperrider 1955; G. L. Stebbins et al. 1963; T. S. Cooperrider 1986; L. E. McKinney 1992 ...Species 24 (3 in the flora): North America, Mexico, South America, Eurasia, Pacific Islands (Hawaii); introduced nearly worldwide.

Rubus ulmifolius can be distinguished, especially from the closely related R. bifrons and R. vestitus, by its strongly pruinose stems, finely serrate leaflets, and lack of glands throughout.Unlike R. ulmifolius, strongly pruinose native Rubus species lack relatively large and showy pink petals. Some new stems developing from tip-rooting, and early leaves on such stems (especially ...Discussion. Subspecies 3 (3 in the flora). Populus deltoides hybridizes with P. fremontii, the other native species of sect. Aigeiros, in the Colorado Plateau region (Arizona, New Mexico, and Utah) and trans-Pecos Texas.These hybrids involve P. deltoides subsp. wislizeni with both subspecies of P. fremontii and are difficult to distinguish because the parent species are so similar.Species 20 (9 in the flora): temperate North America and eastern Asia. About 35 isoquinoline alkaloids have been isolated from Fumariaceae, and such compounds are present in the tissues of all species. Some of these alkaloids have been used medicinally, mostly in the past. The drug complex corydalis, which contains several alkaloids extracted ...
