Sidalcea keckii is a rare species of flowering plant in the mallow family, known by the common names Keck's checkerbloom and Keck's checkermallow. [1] [2]
The plant is endemic to California, where it is known from the Inner Northern California Coast Ranges and Southern Sierra Nevada foothills.
Three recent occurrences in the southern Sierra, all of which may have been extirpated by now. [3]
The plant was thought extinct in the southern Sierra until it was rediscovered at one site in Tulare County in 1992. This site, which was located on private land, has since been converted for orange groves, possibly eliminating the plant. [4] The owner of the land has not allowed any searches for the plant since then, but the area is considered critical habitat for this federally listed endangered species. [4]
Sidalcea keckii is an annual herb growing up to 35 centimeters tall which is bristly from top to base. The leaves have blades shallowly edged or deeply divided into lobes, the upper blades with toothed edges.
The inflorescence is a dense cluster of a few flowers with deep pink petals measuring 1 to 2 centimeters long. Each flower has a calyx of pointed green sepals which may be streaked with pink. The bloom period is April and May.
Sidalcea pedata, also called birdfoot checkerbloom or Big Bear checkerbloom, is a rare and endangered perennial herb of California. It blooms between May and July. However, it is an endemic species of California and only occurs in few places in the San Bernardino Mountains, primarily at Bear Valley, Bluff Lake. It grows at 1500–2100 m elevation in moist meadows to open woodlands and the unique pebble plain habitat of the area. Since Big Bear Valley is a resort destination, the birdfoot checkerbloom is threatened by development, vehicles and grazing.
