Walter’s Violet (Viola walteri)
DESCRIPTION: Upright or creeping perennial herb to 1 dm.; flowering April, May; fruiting May, June.
SIMILAR SPECIES: Viola walteri is similar in appearance and closely related to V. conspersa. V. walteri is separated by its overall pubescence and stoloniferous nature. However, Russell (1965) states that where these species come in contact (i.e. southern Ohio and southeastern Tennessee), they intergrade and many specimens from these areas are difficult to assign to either species.
TOTAL RANGE: FL to TX, n. to WV, s. OH, KY, and AR.
STATE RANGE: Post-1990 record from Adams, Highland and Ross counties. There is a 1916 specimen from Franklin County.
HABITAT: Open woods and rocky ledges, usually in calcareous substrates; frequently collected on dolomite outcrops and promontories.
THREATS: Overshading by woody species as a result of succession; trampling of outcrop and promontory populations
RECOVERY POTENTIAL: Perhaps good due to its tolerance of moderate disturbance.
INVENTORY GUIDELINES: Mature flowering material is needed for positive identification; avoid over-collecting.
COMMENTS: This species may be more frequent in Ohio than current records indicate. It may be overlooked due to its creeping habit and small flowers. It should be sought in the proper habitat throughout the southwestern part of the state.
