Loch Lomond Vernal Pool Ecological Reserve - Other Rare Plants

Other Rare Plants

• Many-flowered navarretia (Navarretia leucocephala ssp. plieantha)

The many-flowered navarretia is state (1979) and federal (1997) listed as endangered. It grows in wetland habitats near Ponderosa pine woodlands. An annual wildflower of the Phlox family (Polemoniaceae) that has only been found in the California counties of Lake, Sonoma and Napa. The plant form is a prostrate mat, flowers are clusters of white or blue with the bloom period in May through June. Identification is difficult as the many-flowered navarretia closely resembles the few-flowered navarretia and Baker's navarrettia and will hybridize with few-flowered navarretia.

• Few-flowered navarretia (Navarretia leucocephala ssp. pauciflora)

The few-flowered navarretia is state (1990) and federal (1997) listed as endangered. Very similar to many-flowered navarretia, differences include smaller white or blue flowers and the plant stems are white with purple streaks. The species account from US Fish and Wildlife Service, Sacramento reports that only Napa County has a population of few-flowered navarretia remaining. Historically, there were populations at the Loch Lomond reserve, Boggs Lake reserve, and in Sonoma County.
