Definition
Viola bakeri, commonly known as Baker’s violet, is a species of flowering plant in the family Violaceae. It is a perennial herbaceous violet native to parts of western North America.
Overview
Viola bakeri occurs in mountainous regions of the western United States, primarily within the Sierra Nevada, the Cascade Range, and adjacent foothills. The species typically inhabits moist alpine and sub‑alpine meadows, forest edges, and streambanks at elevations ranging from roughly 1,500 to 3,000 m (5,000–10,000 ft). It is a relatively low‑growing plant that forms part of the seasonal flora of these habitats.
Etymology / Origin
The specific epithet bakeri honours the British botanist John Gilbert Baker (1834–1920), who made significant contributions to the taxonomy of the Violaceae. The name was formally published by Edward Lee Greene in 1885.
Characteristics
- Growth habit: Perennial herb arising from a short rhizome; typically 5–15 cm tall.
- Leaves: Basal rosette of simple, ovate to lanceolate leaves with toothed margins; leaf surfaces are slightly pubescent.
- Flowers: Solitary, five‑petaled blooms borne on short peduncles. Petals are generally white to pale violet with a darker violet vein or blotch on the lower petal. Flowering occurs from late spring through midsummer.
- Reproductive structures: After pollination, the plant produces a small, dehiscent capsule containing numerous tiny seeds equipped with elaiosomes for ant dispersal (myrmecochory).
- Ecology: The species is adapted to cold, moist environments and can tolerate light snow cover. Its low stature and early flowering period enable it to complete its reproductive cycle before the onset of the short alpine summer.
