narrow involucres, in the calyx teeth broadening towards 

 the top, in the shorter and less thick clothing of hair, in 

 the more deeply-cut corolla lobes, in the capsule shorter 

 in proportion to the calyx, and in the smooth, not papillose, 

 epidermis of the seeds. When the plant grows on rocks, 

 the root stock is covered with withered leaves, as in 

 P. Allionii. 



E. Cyanopis, Schott. — This group contains one species. 



20. P. glutinosa, Wulf. — Found in Lower Engadine, 

 N. and S. Tyrol, Carinthia, Styria, Carniola, Salzburgh, 

 N.-E. Italy — on schist. Leaves somewhat fleshy, glutinous, 

 hardly shining, with something of a cartilaginous margin 

 towards the apex, punctate on the surface, lanceolate- 

 cuneate or oblong-lanceolate, with obtuse or rounded apex, 

 margin rarely entire, generally denticulate, with seven to 

 nine teeth. Involucral bracts oval, rounded at the apex, 

 equal to or overtopping the calyx. Calyx brownish red, 

 teeth oval, obtuse, adpressed to the corolla tube. Flowers 

 very fragrant, at first dark blue, later violet, very seldom 

 white, with a dark ring above the throat. Anthers of the 

 short-styled flowers inserted in, or beneath, the throat. 

 Capsule a little shorter than the calyx. 



I have never seen a more beautiful sight than a large 

 bed of this Primula on the Muttenjoch, in the Gschnitzthal, 

 in full flower, and exquisitely fragrant in the fresh breeze 

 blowing over the summit of the Pass. 



F. Cham^gallis, Schott. — This group also contains only 

 one species, P. minima, with its hybrids. Its characters 

 are — Leaves fleshy-coriaceous, smooth, glabrous, with the 

 exception of the capitate hairs, more rarely sub-hirsute or 

 sub-villous, with somewhat cartilaginous points, and with 

 hardly any distinct cartilaginous border Involucral bracts 

 elongated, narrow. Flowers subsessile, rosy or white. 

 Calyx somewhat long. Lobes of corolla bifid or deeply 

 emarginate, obcordate, hairy towards the villous throat, 

 which is destitute of folds. Outer covering of seeds plane. 



21. P. minima, L. — Found on the Eastern Alps and 

 mountains of eastern Europe. Not in Switzerland. On 

 schist, granite.
