Plagiobothrys mollis is a species of flowering plant in the borage family known by the common name soft popcornflower. It is native to Oregon, Nevada, and the Sierra Nevada of California, where it grows in scrub and grassy habitat, especially in moist and wet areas.

Boraginaceae Family of plants

Boraginaceae, the borage- or forget-me-notfamily, includes a variety of shrubs, trees, and herbs, totaling about 2,000 species in 146 genera found worldwide.

Oregon State of the United States of America

Oregon is a state in the Pacific Northwest region on the West Coast of the United States. The Columbia River delineates much of Oregon's northern boundary with Washington, while the Snake River delineates much of its eastern boundary with Idaho. The parallel 42° north delineates the southern boundary with California and Nevada. Oregon is one of only three states of the contiguous United States to have a coastline on the Pacific Ocean.

Nevada State of the United States of America

Nevada is a state in the Western United States. It is bordered by Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast and Utah to the east. Nevada is the 7th most extensive, the 32nd most populous, but the 9th least densely populated of the U.S. states. Nearly three-quarters of Nevada's people live in Clark County, which contains the Las Vegas–Paradise metropolitan area where three of the state's four largest incorporated cities are located. Nevada's capital, however, is Carson City.

Description

It is a perennial herb producing small, decumbent stems running along the ground and rooting at nodes. It is very hairy in texture, the hairs soft and long. The leaves on the stem may be arranged alternately or oppositely. The inflorescence is a series of tiny white flowers up to 1 centimeter wide.

Inflorescence Term used in botany to describe a cluster of flowers

An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. Inflorescence can also be defined as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern.

Varieties

There are two varieties of this plant. Most incidences are var. mollis.
The other variety, var. vestitus, is known only from the type specimen collected in the 19th century near Petaluma, California. It has not been seen since, and is presumed extinct.

Type (biology) Specimen(s) to which a scientific name is formally attached

In biology, a type is a particular specimen of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralize the defining features of that particular taxon. In older usage, a type was a taxon rather than a specimen.

Petaluma, California City in California, United States

Petaluma is a city in Sonoma County, in California's Wine Country, part of the North Bay sub-region of the San Francisco Bay Area, located 37 mi (60 km) north of San Francisco. Its population was 57,941 according to the 2010 Census.

Extinction Termination of a taxon by the death of the last member

In biology, extinction is the termination of an organism or of a group of organisms (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" after a period of apparent absence.
