A. caucasica Willd., Enum. Hort. Berol. Suppl. (1813). Syn: A. albida Stev. ex Bieb., Fl. Taur.-Cauc. 3: 446 (1819) sensu lato; A. alpina L. subsp. caucasica (Willd.) Briq., Prodr. Fl. Corse, 1: 48 (1913).
Perennial herb. Stems ascending to erect. Rosette leaves variable, usually obovate, petiolate or sessile, dentate with rather obtuse teeth. Stem leaves usually oblong, auriculate; all densely to sparsely stellate-canescent. Petals white, frequently drying yellowish, 12-16(-18) mm. Siliquae strongly compressed, somewhat strangulate between the seeds, strict to spreading. A complex species which can be further divided (cf. Cullen in Notes R.B.G. Edinb. 26: 188 (1965)).
1. Lower leaves tapering, without distinct petioles, usually with more than 4 teeth; pedicels straight, erect or spreading  subsp. caucasica
1. Lower leaves clearly petiolate, entire to 2-4-toothed; pedicels arcuate-incurved  subsp. brevifolia

Balkans, Caucasia, W. Syria, Iran. A very variable taxon; plants from the east of the range tend to have rather strict siliquae, whereas those from the west have them spreading - a correlation which breaks down fairly often. The numerous varieties accepted by Boissier and other workers seem to be no more than habitat modifications.
