Lepechinia rossii is a rare species of flowering plant in the mint family known by the common name Ross' pitcher sage.

Contents

It is endemic to the Transverse Ranges of California on the north edge of the Greater Los Angeles Area. This species was first described to science only in 2006. [2]

Distribution

The plant is known from four occurrences, two in the Topatopa Mountains of Ventura County near Fillmore, and two in the Sierra Pelona Mountains east of Castaic Lake in Los Angeles County. [1] The former location spans about 3 kilometres (1.9 mi), and the latter location contains no more than about 1000 individual plants. [1]

Its habitat is chaparral of the California chaparral and woodlands ecoregion. [2]

Description

Lepechinia rossii is a perennial herb or shrub with hairy, glandular herbage. The leaves have toothed or serrated oval blades measuring up to 13 centimeters long.

The inflorescence is an open raceme of flowers with large, leaflike bracts at the base. The flowers have bell-shaped calyces of reddish or purple-tinged sepals and bell-shaped white or purplish corollas.

Conservation

Threats to this rare species include off-road vehicles, power line maintenance activity, petroleum drilling and exploration, introduced plant species such as brome grasses, and alterations in the fire regime in the southern California chaparral where it grows. [1] [2]

<i>Lepechinia fragrans</i> Species of shrub

Lepechinia fragrans is a flowering herbaceous shrub known by the common names island pitchersage and fragrant pitchersage. It is a member of the Lamiaceae, or mint family, but like other Lepechinia, the flowers are borne in racemes instead of in mintlike whorls.

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

Lepechinia is a genus of plants in the mint family, Lamiaceae. It includes several species of plants known commonly as pitchersages. Plants of this genus can be found in Central and South America, Mexico, California, Hispaniola, and Hawaii, although the species in Hawaii is probably a human introduction. Many of them bear attractive pitcher-shaped flowers, often in shades of purple. The genus was named for the Russian botanist Ivan Ivanovich Lepechin. Recently, the two monotypic genera Chaunostoma and Neoeplingia were shown to be part of Lepechinia.
