one — p. Falinuri, Pet. — is found in the neighbourhood of 

 Naples ; while three — P. minima, L., P. chcsiana, Tsch., 

 and P. auricula, L. — travel as far east as the Carpathians. 

 Their chief home is the Tyrol and Carinthia. They do 

 not occur in the north of Europe. 



A. The section Auricula has been divided by Schott 

 into different groups of species. The first of these is that 

 of Auricula proper, or Euaukicula, with yellow, or violet, 

 heterostyle flowers ; a short calyx ; a corolla marked with 

 a zone of farina near its base ; short, broad, involucral 

 bracts ; farinose leaves bearing glandular hairs ; and a 

 short, globose or oval capsule. 



1. P. Auricula, L. — Very widely distributed over the 

 Swiss and Austrian Alps : also in the Pyrenees, Jura, 

 Apennines, Carpathians. Leaves quite entire, or repand- 

 denticulate ; leaves, calyx, and flowers white-farinose : 

 flowers yellow, fragrant. There is a well-marked variety 

 {alhocinctd) with comparatively little farina on the surface 

 of the leaves, which, however, have a conspicuous, white, 

 farinaceous border. This seemed to be the prevailing form 

 in the neighbourhood of Val Daone. Another variety 

 {nuda), which occurs in the Dolomite district, has farina 

 only on the calyx. Still another variety {monairnsis), 

 found sparingly on the Alps, but in greater quantity in the 

 neighbourhood of Munich, is distinguished by its very 

 broad leaf-stalk and its narrow spread of leaf. 



P. Balbisii, Lehm., is a sub-species of P. auricula, L., in 

 which the green parts of the plant are destiture of farina, 

 and the gland-bearing hairs are longer, being dense on the 

 margins of the leaves, but occurring more sparingly on 

 their surlace. The colour of the Hovvers is a darker 

 yellow, not so bright as in P. aaricula, and they are 

 without scent. This is P. ciliata, of Moretti. 



2. P. Palinuri, Pet., is the only other yellow Auricula. 

 It occurs in the neighbourhood of Cape Palinurus, in Italy. 

 Apart from its being, in general, a larger plant, its main 

 difference from P. auricula lies in the fact that, instead of 

 the cartilaginous leaf-border and short sepals of the latter, 

 the leaves are only cartilaginous at the points of the teeth, 

 and the sepals are large and leaf-like.
