Springville Clarkia

Clarkia springvillensis

Clarkia springvillensis is a rare species of flowering plant in the evening primrose family known by the common name Springville clarkia. It is endemic to central Tulare County, California, where it is known from fewer than 20 occurrences around Springville. It is a federally listed threatened species. A few populations of this plant are located on private land, but several others grow on land at least partially protected by the California Department of Fish and Game, the Bureau of Land Management, and the US Forest Service within the bounds of Sequoia National Forest. Threats to the species include non-native plant species, road maintenance, grazing and trampling by livestock, and development; the population growing on the type locality near Springville was extirpated when the land was made into a mobile home park. Clarkia springvillensis is an annual herb growing erect to approach a maximum height near 1 metre (3. 3 ft). The lance-shaped leaves are up to 9 centimeters long. The herbage is hairless and waxy in texture. The inflorescence bears open flowers and hanging, closed flower buds. The deep red sepals remain fused together as the petals bloom from one side. Each petal is a diamond-shaped blade at the end of a long claw. It is pinkish-lavender with a purple spot at the base. There are 8 stamens, some with large, red anthers and some with smaller, paler anthers. The stigma protrudes from the center. Clarkia springvillensis was first described by Frank Charles Vasek in a 1964 issue of Madroño, the journal of the California Botanical Society.

Temblor Range Clarkia

Clarkia tembloriensis

Clarkia tembloriensis is a rare species of flowering plant in the evening primrose family, known by the common name Temblor Range clarkia. The wildflower is endemic to California, where it is native to the San Joaquin Valley, and into the adjacent Inner South California Coast Ranges on its west, including the namesake Temblor Range, and occasionally into the Sierra Nevada foothills on its southeast. It is found in chaparral scrub and grassland habitats, at 100-500 metres (330-1,640 ft) in elevation. Clarkia tembloriensis is an erect annual herb exceeding 0. 5 metres (1. 6 ft) in maximum height. The lance-shaped leaves are gray-green in color and waxy, reaching 7 centimeters long. The inflorescence has open flowers and hanging closed buds. The fuzzy greenish sepals stay fused together as the petals bloom from one side. The herbage may be tinted with red. The flower petals have diamond-shaped blades at the end of long claws. They are pinkish-lavender, sometimes with a large purple spot near the base. There are 8 stamens, some with large red or purple anthers and some with smaller, paler anthers. Subspecies. Hybrids between subspecies have low fertility. The two current subspecies are: Clarkia tembloriensis ssp. calientensis - Vasek's clarkia - found at only three sites near Caliente Creek in the Caliente Hills, at ~500 feet (150 m) in an ecotone of the Sierra Nevada foothills and San Joaquin Valley, in Kern County. The most rare of the subspecies, it is considered vulnerable to extinction with such small populations located on privately owned land. Clarkia tembloriensis ssp. tembloriensis (syn: Clarkia tembloriensis subsp. longistyla) - Temblor Range clarkia - distribution along the western San Joaquin Valley into the eastern Inner South California Coast Ranges, from the Diablo Range to the Temblor Range and Carrizo Plain areas.
