Viola lyallii is one of three New Zealand native species of Viola. This small tap-rooted perennial grows throughout the North and South Islands, but it is uncommon north of the Waikato. Its habitat is wetlands and damp areas within riparian forests from coastal to subalpine altitudes.
The green leaves (>4cm) are kidney-shaped and have spaced shallow notches on their margins. 
Flowering occurs from November to January. The small flowers that appear above the plant on weak stems have white petals that have purple veins radiating from the flowers centre.
