Fritillaria ojaiensis is a rare species of fritillary lily known by the common name Ojai fritillary.

Contents

This wildflower is endemic to California, with a discontinuous distribution in northwestern and west-central parts of the state. It occurs in the western Transverse Ranges of Monterey, San Luis Obispo, Santa Barbara, and Ventura Counties, including the Santa Ynez Mountains, and the southern Santa Lucia Mountains. [1] Additional populations have been found along the coast of Mendocino County approximately 400 miles to the north. [2]

Endemism ecological state of being unique to a defined geographic location or habitat

Endemism is the ecological state of a species being unique to a defined geographic location, such as an island, nation, country or other defined zone, or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. The extreme opposite of endemism is cosmopolitan distribution. An alternative term for a species that is endemic is precinctive, which applies to species that are restricted to a defined geographical area.

California State of the United States of America

California is a state in the Pacific Region of the United States. With 39.6 million residents, California is the most populous U.S. state and the third-largest by area. The state capital is Sacramento. The Greater Los Angeles Area and the San Francisco Bay Area are the nation's second and fifth most populous urban regions, with 18.7 million and 9.7 million residents respectively. Los Angeles is California's most populous city, and the country's second most populous, after New York City. California also has the nation's most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The City and County of San Francisco is both the country's second-most densely populated major city after New York City and the fifth-most densely populated county, behind only four of the five New York City boroughs.

Disjunct distribution Ecology

In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species range.

The plant is named for the City of Ojai in Ventura County. [3]

Ojai, California City in California, United States

Ojai is a city in Ventura County in the U.S. state of California. Located in the Ojai Valley, it is northwest of Los Angeles and east of Santa Barbara. The valley is about 10 miles (16 km) long by 3 miles (5 km) wide, surrounded by hills and mountains. The population was 7,461 at the 2010 census, down from 7,862 at the 2000 census.

Ventura County, California County in California, United States

Ventura County is a county in the southern part of the U.S. state of California. As of the 2010 census, the population was 823,318. The largest city is Oxnard, and the county seat is the city of Ventura.

Description

Fritillaria ojaiensis produces an erect stem reaching maximum heights near 0.5 metres (1.6 ft). The long, straight, very narrow leaves grow in whorls on the lower stem and in pairs near the top. [4]

Flowers are produced at intervals. Each nodding flower has six tepals one to three centimeters long and greenish yellow to purple in color with purple mottling. At the center is a large nectary surrounded by stamens with large yellow anthers. [4]

Tepal

A tepal is one of the outer parts of a flower. The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated, as in Magnolia, or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another. The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal".

Gynoecium collective term for all carpels in a flower

Gynoecium is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of pistils and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes, the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells.

Stamen floral organ

The stamen is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium.

This plant is similar to Fritillaria affinis and is sometimes considered the same species. [4]
