Subspecies: V. lanceolata ssp. lanceolata; V. lanceolata ssp. vittata; V. lanceolata ssp. occidentalis[2]
Description
Viola lanceolata is a dioecious perennial forb/herb.[2]
Distribution
This species occurs from New Brunswick, westward to Minnesota, and southward to Florida and eastern Texas.[1]There have also been reports along the Pacific coast in British Columbia, Washington, Oregon, and California.[2]
Ecology
Habitat
V. lanceolata is found in boggs, seepage slopes, pitcher plant seepage bogs, streamheads and their margins, small swamp forests, depression ponds, interdune swales and ponds, and other wet habitats.[1]
Phenology
In the southeastern and mid-Atlantic United States, flowering occurs from February through May.[1] On the Florida panhandle, flowering has been observed from November through May, peaking in March and April.[3]
Seed bank and germination
At an Ontario lake, the frequency of V. lanceolata was 97 at 0.2-0.8 m below the maximum water level and 100 and 13 at 0.8-1.3 m and 1.3-1.5 m, respectively. The mean number of collected seeds that germinated from this lake was 17.4 seeds dm-2.[4]
