velvety and grey-green beneath. Calyx canipanulate, 

 inflated, whitish yellow ; teeth broadly ovate or triangular, 

 shortly acuminate. Corolla small, concave, egg yellow, 

 less commonly sulphur yellow. Capsule oval, only half as 

 long as the calyx. 



Ahnost everywhere throughout Europe, reaching to an 

 altitude of 4000 feet. 



Var. Paiinonica, Keruer. — Leaves oval or oblong, 

 generally contracted gradually into the winged petiole, 

 underneath hoary-tomentose. Calyx widely campanulate. 

 This is var. injiata, Pax. 



Hungary, Lower Austria, Maritime Alps, Pyrenees, etc. 



Var. (sub. sp. ?) Colaniiuc (Ten.) Pax. — Leaves ovate or 

 cordate, suddenly narrowed into the narrowly winged 

 petiole, underneath snowy - tomentose, thickly felted. 

 Corolla, as in var. Pannonica, somewhat flatter than in 

 the type. 



Found over the whole ^Mediterranean region. 



Var. Tommudnii, Gr. Godr. — Corolla sulphur yellow 

 (as in P. elatior), with five orange spots, almost flat, 

 otherwise like P. Columnce. — Mte. Maggiore, near Fiume, 

 and Pic de I'Hieris in the Pyrenees. 



The four forms, officinalis, Pannonica, Cohimnce, and 

 Tomrnasiiiii, pass imperceptibly into one another, so that 

 many plants may be equally well referred to one or to 

 another of them. Keruer regards the most distinct 

 difference to lie in the form and size of the corolla : he 

 unites Columnce with Tommasinii. These two can be 

 distinguished only by the flowers, which in the former are 

 bell-shaped and egg yellow, as in P. officinalis, while in the 

 latter they are flat, or almost flat, and sulphur-coloured, as 

 in P. elatior. 



Xotc. — In compiling this account of the European 

 Primulte, I am specially indebted to two works which I 

 have used freely, viz. " Monographische L^ebersicht iiber die 

 Arten der Gattung Primula," von Dr. Ferdinand Pax, 

 Leipzig, 1888, and "Die europaischen Arten der Gattung 

 Primula," von E. Widmer, Mlinchen, 1891.
