Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Seep Monkeyflower - (Monkeyflower species) Seep

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This small community is known from California''s Coast Ranges, Sierra Nevada below 1220 m (4000 feet) elevation, and northeastern California, as well as central and southern Utah and Colorado. Mimulus guttatus is a small, delicate herb growing within the splash zone of small first-order streams, seeps, springs and hanging gardens. It occurs from 300 to 2390 m (1000-7840 feet) in elevation. This community is often found in narrow linear strips, occasionally broadening into small hollows, often overlooked for sampling, but universally recognized. It can occur on very steep cascades and waterfalls, on flat to steep seeps, or along gentle streams and floodplains (3-5%). The floristic composition is variable; several different species of Mimulus (Mimulus guttatus, Mimulus lewisii, Mimulus moschatus) may be the most dominant present. Generally mosses are present, as well as several other water-dependent herbaceous plants such as Stellaria media, Collinsia heterophylla, Cardamine spp., Eleocharis spp., Epilobium spp., Equisetum arvense, Carex spp., Salix spp., Juncus spp., Veronica americana, Nasturtium officinale, Cardamine spp., and Nasturtium spp. Graminoid species are usually present as well, often less abundant than the forb component, but usually very mesic.

Floristics: The floristic composition is variable; several different species of Mimulus (Mimulus guttatus, Mimulus lewisii, Mimulus moschatus) may be the most dominant present. Generally, mosses are present, as well as several other water-dependent herbaceous plants such as Stellaria media, Collinsia heterophylla, Cardamine spp., Eleocharis spp., Epilobium spp., Equisetum arvense, Carex spp., Salix spp., Juncus spp., Veronica americana, Nasturtium officinale (= Rorippa nasturtium-aquaticum), Cardamine spp., and Nasturtium spp. Graminoid species are usually present as well, often less abundant than the forb component, but usually very mesic. Occasionally, the graminoid component may be more abundant, and the Mimulus spp. component serves as an indicator species to this community.

Environmental Description:  Mimulus guttatus is a small, delicate herb growing within the splash zone of small first-order streams, seeps, springs and hanging gardens. It occurs from 300 to 2390 m (1000-7840 feet) in elevation. This small community is often found in narrow linear strips, occasionally broadening into small hollows, often overlooked for sampling, but universally recognized. It can occur on very steep cascades and waterfalls, on flat to steep seeps, or along gentle streams and floodplains (3-5%) often bordered by a wet meadow community (graminoid- or forb-dominated). Substrates include mixed alluvium, serpentinite, and volcanics.

Geographic Range: This small community is known from California''s Coast Ranges, Sierra Nevada below 1220 m (4000 feet) elevation, northeastern California, the Cascades of Oregon, central and southern Utah, and Colorado.
