    Watson, J.M. and Flores, A.R. 2020. Queen of all she surveys. A remarkable and distinct new rosulate viola (section Andinium W. Becker), a single-site endemic from the central Andes of Chile. International Rock Gardener 122:



Distribution and habitat

Only known from an east-west spur of the central temperate Andes south of the Aconcagua River as a diffuse population of several dispersed colonies of variable sizes. (Watson & Flores 2020a). Occurs at the subnival zone just over 3000 m, forming colonies of scattered individuals on shallow rocky slopes and gently rounded to flat-topped ridge crests almost devoid of other vegetation (Watson & Flores 2020a).

Key characteristics

This is a very distinctive as it differs from most others of the alliance (section Andinium) by its usually wide, frequently dome-shaped rosettes, and from all others by its large, heavily and densely black or inky blue-veined corolla, the lateral petals bearded with long, flattened, translucent white, clavate hairs. The flowers are set as a corona on and within the face of the rosette, a character otherwise only found in Viola coronifera and Viola comberi, both of which have smaller-sized yellow or orange flowers and lateral petals short-bearded at the base only (Watson & Flores 2020a)
