the longer and closer-set hairs, as also by the somewhat 

 broader leaves, which have shorter petioles, and are less 

 bluntly toothed, while the comparative length of capsule 

 and calyx is nearly the same. 



Widmer remarks that he does not venture to join it 

 as a variety to P. villosa and F. comviutata, to which it 

 approaches nearest in habit and other characters, because 

 the localities in which it is found are separated from the 

 home of the latter by a wide tract of country yielding 

 distinct species {P. hirsnta, All., and P. cenensis). He is 

 of opinion that it is more intimately connected with 

 P. hirsnta, All, from which it difters in its longer flower 

 stalk, ill the leaves more gradually narrowed into the 

 petiole, in its longer hairs which have less highly coloured 

 glands, in its shorter peduncles, in its calyx teeth closer 

 to the tube of the corolla, and in its capsule being longer 

 as compared with the calyx. 



The colour of the flowers of P. villosa, P. comimttata, 

 P. cottia, and P. hirsuta, All., is very much the same. 



17. P. VILLOSA, Jacquin. — On the Alps of Styria, 

 Carinthia, and Carniola — on granite. Leaves obovate or 

 oblong, gradually narrowed into the shortish petiole, more 

 rarely almost suddenly contracted, apex obtuse or rounded, 

 more rarely sub-truncate, toothed from the middle or only 

 near the apex, with small close teeth, sometimes quite entire, 

 the surface and margin somewhat densely covered with 

 longish glandular hairs ; glands small, red ; peduncles 

 short ; capsule generally a little longer than the calyx ; 

 flowers lilac or rose ; inner part of corolla mostly pure white. 



Closely allied to P. cenensis. — The variety norica of 

 Kerner is the smaller leaved form, with the hairs shorter, 

 and not so thickly distributed. The leaves are generally 

 narrow and truncate. 



Sub-sp. P. 'coMMUTATA, Schott, is distinguished by 

 thinner leaves, the blade and stalk of which are longer, by 

 larger, more distant teeth, a somewhat longer calyx, and 

 somewhat shorter capsule. These points are not constant 

 enough to mark a distinct species. 



P. The next two species form a group to which Schott 

 gives the name PiHOPSIDIUM. The leaves are fleshy, with
