 et 3 mm lata, utrinque irregulariter dentibus obtusis 1 — 2 notata, juvenilia basi dilatata, 

 obtusa, pilis stellatis vel simplieibus minute farinoso-cinerascentia. Scapus 2 — 6-fiorus, 

 1 — 3 cm longus, pilis stellatis farinoso-cinerascens. Bracteae ovato-lanceolatae, acutae, 

 cum calycis laciniis pube stellari obteetae. Pedicelli brevissimi, demum ad 5 mm longi, 

 bracteis minores, summum eas subaequantes. Calycis usque ad medium partiti tubus 

 glaber, pallidus, 3 mm longus; laciniae lanceolatae, acutae; corollae violaceae tubus

Nota. Species meo sensu certe cum D. Dieckeana congruit. Specimina typica D. dentatae 

 non vidi; nequaquam autem D. Dieckeana cum D. nivali conjungenda est.
