Viola emarginata [phasmatifolia variant]

Common names:

None.

Synonyms:

None.

Description:

Growth form, foliage and peduncle color and indument same as the species; petioles prominently winged; leaf blade outline broadly oblong, leaf blades of some plants resembling a walkingstick insect (Diapheromera femorata), the central axis narrowly oblong-linear, each margin with 2–4 long slender variously bent processes; chasmogamous flowers same as the species, cleistogamous fruits and seeds unknown.

Ecology:

Somewhat acidic, well-drained sandy soils in oak and oak-pine forests, and open sites along forest borders and roadsides adjacent to open woodlands.

Distribution:

Piedmont of s.-c. VA south to c. NC.

Rarity:

None.

Phenology:

Same as V. emarginata sensu lato.

Affinities:

Same as V. emarginata sensu lato.

Comments:

This narrow regionally endemic variant is highly distinctive vegetatively. It should be sought in mature cleistogamous fruit to document capsule and seed morphology. Needs further study.

Literature Cited:

None.
