Caulis erectus vel aseendens, rarissime simplex, plerumque in 

 parte inferiore ramosus 40 cm. altus, viridis vel rubescens vel 

 fuscescens pilis crispulis reversis albidis et ad nodos, hinc inde 

 etiam in internodiis pilu longis glandnliferis piibescens, ramis sub- 

 oppositis ascendentibus hinc inde iterum ramosis. Folia caulina 

 infima cuueata obtusa dentibus utrinque paucis obtusis, media et 

 superiora ovata, breviter acuminata, dentibus utrinque 3-6 acutis sed 

 non aristatis. BractefB suboppositfe, foliis caulinis similes sed latiores 

 et breviores sensim diminutse et ad apicem inflorescentije Sc-epe basi 

 cuneattc, dentibus acutioribus sed non aristatis. Folia omnia viridia 

 rarius rubescentia, in regione alpina hinc inde nigro-marginata, 

 subtus plicato-striata setulis albidis eglandulosis et (saltern bracteffi ad 

 basin) pilis lon^/is f/landuliferis plus minus dense obsita. Spica initio 

 condensata, mox elongata. Flores subsessiles. Calyx indumento ei 

 foliorum conformi obtectus, semper (jlandulosus, fructifer non accretus. 

 Corolla magna, initio in dorso circa 9-11, fine anthesis 11-14 mm. 

 longa, tubo fine anthesis elongato calycem conspicue superante, 

 labio superiore bilobo, lobis emarginatis vel bilobis reflexis, labio 

 inferiore trilobo lobis profunde emarginatis. Corolla plerumque 

 alba labio superiore violaceo, labio inferiore macula lutea et striis 

 violaceis picto, fauce luteo ; hinc inde tota plus minus violascens ; 

 rarius etiam superiore albo. Capsula elliptica emarginata, calycis 

 denies nou vel parum superans, margine longe erecto-ciliata,caeterum 

 breviter pilosa.
