Flora of North America

Last updated

The Flora of North America North of Mexico (usually referred to as FNA) is a multivolume work describing the native plants and naturalized plants of North America, including the United States, Canada, St. Pierre and Miquelon, and Greenland. It includes bryophytes and vascular plants. All taxa are described and included in dichotomous keys, distributions of all species and infraspecific taxa are mapped, and about 20% of species are illustrated with line drawings prepared specifically for FNA. It is expected to fill 30 volumes when completed and will be the first work to treat all of the known flora north of Mexico; [1] in 2015 it was expected that the series would conclude in 2017. [2] Twenty-nine of the volumes have been published as of 2022. [3]


Soon after publication, the contents are made available online. [4] [5] [1]

FNA is a collaboration of about 1,000 authors, artists, reviewers, and editors from throughout the world. [5]


The series has been praised for "the comprehensive treatments [that] allow botanists to examine taxonomic and geographical traits of genera across the North American continent, rather than being limited by keys developed for one's own state or region". [6]

Reviewing volume 3, Paula Wolfe found the series worth recommending, and praised it for high standards. [1]

<i>Trillium</i> Genus of flowering plants

<i>Erythronium</i> Genus of flowering plants

Erythronium, the fawn lily, trout lily, dog's-tooth violet or adder's tongue, is a genus of Eurasian and North American plants in the lily family, most closely related to tulips. The name Erythronium derives from Ancient Greek ἐρυθρός (eruthrós) "red" in Greek, referring to the red flowers of E. dens-canis. Of all the established species, most live in North America; only six species are found in Europe and Asia.

<i>Trillium chloropetalum</i> Species of flowering plant

Trillium chloropetalum, also known as giant trillium, giant wakerobin, or common trillium, is a species of flowering plant in the family Melanthiaceae. It is endemic to the western U.S. state of California, being especially frequent in and around the San Francisco Bay Area.

<i>Trillium erectum</i> Species of flowering plant

Trillium erectum, the red trillium, also known as wake robin, purple trillium, bethroot, or stinking benjamin, is a species of flowering plant in the family Melanthiaceae. The plant takes its common name "wake robin" by analogy with the European robin, which has a red breast heralding spring. Likewise Trillium erectum is a spring ephemeral plant whose life-cycle is synchronized with that of the forests in which it lives. It is native to the eastern United States and eastern Canada from northern Georgia to Quebec and New Brunswick.

<i>Moringa</i> (genus) Genus of flowering plants

<span class="mw-page-title-main">Orobanchaceae</span> Family of flowering plants known as broomrapes

Orobanchaceae, the broomrapes, is a family of mostly parasitic plants of the order Lamiales, with about 90 genera and more than 2000 species. Many of these genera were formerly included in the family Scrophulariaceae sensu lato. With its new circumscription, Orobanchaceae forms a distinct, monophyletic family. From a phylogenetic perspective, it is defined as the largest crown clade containing Orobanche major and relatives, but neither Paulownia tomentosa nor Phryma leptostachya nor Mazus japonicus.

<i>Tiarella cordifolia</i> Species of flowering plant

Tiarella cordifolia, the heart-leaved foamflower, is a species of flowering plant in the family Saxifragaceae. The specific name cordifolia means "with heart-shaped leaves", a characteristic shared by all taxa of Tiarella in eastern North America. It is also referred to as Allegheny foamflower, false miterwort, and coolwort.

<i>Tiarella</i> Genus of flowering plants in the family Saxifragaceae

Tiarella, the foamflowers, is a genus of flowering plants in the family Saxifragaceae. The generic name Tiarella means "little turban", which suggests the shape of the seed capsules. Worldwide there are seven species, one each in eastern Asia and western North America, plus five species in eastern North America. As of October 2022, the taxonomy of Tiarella in eastern North America is in flux.

<span class="mw-page-title-main">Tofieldiaceae</span> Family of flowering plants

Tofieldiaceae is a family of flowering plants in the monocot order Alismatales. The family is divided into four genera, which together comprise 28 known species. They are small, herbaceous plants, mostly of arctic and subarctic regions, but a few extend further south, and one genus is endemic to northern South America and Florida. Tofieldia pusilla is sometimes grown as an ornamental.

<i>Trillium cuneatum</i> Species of flowering plant

Trillium cuneatum, the little sweet betsy, also known as whip-poor-will flower, large toadshade, purple toadshade, and bloody butcher, is a species of flowering plant in the family Melanthiaceae. It is a member of the Trillium cuneatum complex, a subgroup of the sessile-flowered trilliums. It is native to the southeastern United States but is especially common in a region that extends from southern Kentucky through central Tennessee to northern Alabama. In its native habitat, this perennial plant flowers from early March to late April. It is the largest of the eastern sessile-flowered trilliums.

<i>Flora of the Venezuelan Guayana</i>

Flora of the Venezuelan Guayana is a multivolume flora describing the vascular plants of the Guayana Region of Venezuela, encompassing the three states south of the Orinoco: Amazonas, Bolívar, and Delta Amacuro. Initiated by Julian Alfred Steyermark in the early 1980s, it was completed after his death under the guidance of Paul E. Berry, Kay Yatskievych, and Bruce K. Holst. The nine volumes were published between 1995 and 2005 by Timber Press and Missouri Botanical Garden Press.

<i>Dudleya cymosa <span style="font-style:normal;">subsp.</span> marcescens</i> Subspecies of deciduous succulent plant

Dudleya cymosa subsp. marcescens is a species of summer-deciduous succulent plant known commonly as the marcescent dudleya or marcescent liveforever. Throughout the months of spring, it is characterized by a bloom of small, bright-yellow flowers with 5 petals, tinged with orange or red. It is a leaf succulent with a basal rosette, with the foliage withering in summer, going completely leafless, a neotenous trait in the genus. This species is endemic to the exposed volcanic rock of the Santa Monica Mountains in California, being found on shady slopes and outcroppings. It differs from its local congeners with its deciduous habit, slender caudex, and narrower leaf shape, although it is superseded in some of these characteristics by Dudleya parva, growing 13 km to the north, which has even narrower leaves and is quicker to lose them. Because of its restricted distribution and small size, it is vulnerable to habitat degradation and disturbance from acts of graffiti and rock climbers. It is listed as threatened by the United States Fish and Wildlife Service.
