Carex Nigricans
''Carex nigricans'' is a species of sedge known by the common name black alpine sedge. Distribution This sedge is native to western North America from Alaska to the Sierra Nevada in California, to Colorado, where it grows in wet areas in mountain, taiga, and tundra habitat. Description ''Carex nigricans'' produces thick mats and loose clumps of stems up to 30 centimeters tall from a network of short rhizomes. The pistillate flowers have dark bracts and the fruit is covered in a dark colored, long beaked perigynium In botany, a perigynium (plural: perigynia), also referred to as a utricle, typically refers to a sac that surrounds the achene of plants in the genus ''Carex'' (Cyperaceae). The perigynium is a modified prophyll, also known as a glume, which is t .... External linksJepson Manual Treatment - ''Carex nigricans''USDA Plants Profile

Carl Anton Von Meyer
Carl Anton von Meyer (in Russian: Карл Анто́нович фон Ме́йер, ''Karl Antonovich von Meyer'') (1 April 1795 – 24 February 1855) was a Germans, German, Russified botanist and explorer. Meyer was born in Vitebsk. He received his education at the University of Dorpat (1813–14) as a student of Karl Friedrich von Ledebour, with whom he later embarked on a scientific journey to the Crimean Peninsula, Crimea (1818). In 1826, with Ledebour and Alexander G. von Bunge, he took part in an expedition to the Altay Mountains and the Kirghiz Steppe (Kazakhstan). Plants collected on the trip formed the basis of "Flora Altaica" (four volumes issued between 1829 and 1833).JSTOR

Flora Of The West Coast Of The United States
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Flora Of California
California native plants are plants that existed in California prior to the arrival of European colonialism, European explorers and colonists in the late 18th century. California includes parts of at least three Phytochorion, phytochoria. The largest is the California Floristic Province, a geographical area that covers most of California, portions of neighboring Oregon, Nevada, and Baja California, and is regarded as a "world hotspot" of biodiversity. Introduction In 1993, ''The Jepson Manual'' estimated that California was home to 4,693 native species and 1,169 native subspecies or varieties, including 1,416 endemic species. A 2001 study by the California Native Plant Society estimated 6,300 native plants. These estimates continue to change over time. Of California's total plant population, 2,153 species, subspecies, and varieties are endemism, endemic and native to California alone, according to the 1993 Jepson Manual study. This botanical diversity stems not only from the si ...

Perigynium
In botany, a perigynium (plural: perigynia), also referred to as a utricle, typically refers to a sac that surrounds the achene of plants in the genus ''Carex'' (Cyperaceae). The perigynium is a modified prophyll, also known as a glume, which is tissue of leaf origin that encloses the dry, one-seeded achene. In liverworts, "perigynium" refers to a tube-shaped structure which encases the archegonium and the developing sporophyte. The location, size, shape, hairiness, color, and other aspects of the perigynium are important structures for distinguishing ''Carex'' species. They are often subtended by a scale, which may also aid in identification. Dispersal Features of the perigynium may aid in seed dispersal, such as a surface that clings to fur or skin or a shape that enables dispersion via wind or water. Seed dispersal by animals such as ants (myrmechory) has been recorded, as some species of sedges have developed elaiosomes at the base of the perigynia. Ants carry the perigynium ...

Carex
''Carex'' is a vast genus of over 2,000 species of grass-like plants in the family (biology), family Cyperaceae, commonly known as sedges (or seg, in older books). Other members of the family Cyperaceae are also called sedges, however those of genus ''Carex'' may be called true sedges, and it is the most species-rich genus in the family. The study of ''Carex'' is known as caricology. Description All species of ''Carex'' are perennial plant, perennial, although some species, such as ''Carex bebbii, C. bebbii'' and ''Carex viridula, C. viridula'' can fruit in their first year of growth, and may not survive longer. They typically have rhizomes, stolons or short rootstocks, but some species grow in tufts (caespitose). The culm (botany), culm – the flower-bearing stalk – is unbranched and usually erect. It is usually distinctly triangular in section. The leaf, leaves of ''Carex'' comprise a blade, which extends away from the stalk, and a sheath, which encloses part of th ...
