Diplacus douglasii

Diplacus douglasii is a species of monkeyflower known by the common names brownies and purple mouse ears. It is native to the mountains and foothills of California and Oregon, where it is often found on serpentine soils. M. douglasii was first described in a published flora by George Bentham, an English botanist who was considered "the premier systematic botanist of the nineteenth century,. " It was later described by Asa Gray, the father of North American botany. Diplacus douglasii occurs between 45 - 1200 meters elevation in the mountains and foothills of the Cascade and Sierra Nevada Ranges in California and Oregon. It is also found in Southwestern Oregon, Central Western California, and in the Warner Mountains of CaliforniaM. douglasii is classified as a serpentine indicator and hence is most commonly found serpentine soils, but can also be found on bare clay or granitic soils. As a hydrophyte, it is generally found along the upper banks of small creeks, and is classified as a facultative wetland species. However, It is important to note that M. douglasii is equally likely to be found in wetland and non wetland habitats, also occurring in chaparral and foothill woodland communities. Diplacus douglasii flowers between February and April. Growing on serpentine soils, it has adaptations to survive conditions most plants can"t tolerate. Serpentine soils are known to be deficient in essential nutrients for plants. In addition to being low in essential plant nutrients such as nitrogen, calcium, phosphorus, potassium and sulfur, serpentine soils also have high levels of magnesium and heavy metals including nickel, cobalt and chromium, which are toxic to most plants.

Hoover's Downingia

Downingia bella

Downingia bella, also known as Hoover's calicoflower or Hoover's Downingia, is a member of the Bellflower Family (Campanulaceae). The genus is named after A. J. Downing (1815-1852) a noted American horticulturist and landscape architect. This native annual herb is endemic to California and found in valley grassland communities. Its habitat is wetlands, generally vernal pools between 4600 and 5250 feet (1400 to 1600m). As approximately 90% of vernal pools in California have been lost, D. bella is uncommon. The range of D. bella is scattered from locations in Riverside County to areas in the Great Central Valley. Like all Downingia, the stem is decumbent to erect with leaves that are along the stem and often fall before the plant flowers. The flowers are sessile and in a spike inflorescence with individual flowers having a corolla length of 10 to 12 mm. The corolla is glabrous and has 2 distinct lips, the upper with 2 lobes and lower with 3 lobes. The upper lobes are narrowly triangular or elliptic in shape while the lower lobes are obtuse and abruptly toothed. The corolla is blue with the lower lip having a central white field which then has two yellow spots (can be joined) in its middle. At the throat D. bella has 2 raised nipples that generally have 3 alternating purple spots. The 5 fused stamens have anthers that are included in the corolla tube and are angled less than 45 degrees to filaments. The inferior ovary is pedicel-like and is 2 chambered. The fruits of D. bella are between 16 to 18 mm with tough lateral walls that are tardily dehiscent despite no noticeable translucent lines. The seeds within the fruit are longitudinally striate. Some areas in northern Sutter County have D. bella with a minute corolla horn similar to D. ornatissima. Wikimedia Commons has media related to Downingia bella.
