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 subsp. caucasica. Figure 14, p. 261. Syn: A. albida sensu Boiss., Fl. Or. 1: 174-5 (1867) pro maj. parte, excl. var. brevifolia; A. alpina var. flavescens Gris., Spic. 1: 241 (1843); A. alpina subsp. flavescens (Gris.) Hayek, Prodr. Fl. Balc. 1: 404 (1925); A. flaviflora Bunge, PL Abich., No. 26(1858). Fl. 3-8. Rocks, cliffs, slopes, 350-2900 m.   Described from a plant cultivated in the Berlin Botanic Garden.   Widespread, mainly in N. & E. Anatolia. A2 Bursa: Ulu Da., 2000-2180 m, Moore 7264!

C9 Hakkari: Cilo Da., 3300 m, D. 24219!   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.
