Fam. XLI. URTICACEAE. 



175. Urtica dioica L. 

 f U. urens L. 



Fam. XLII. VIOLACEAE. 



Mr. W. Becker of Hedersleben (Germany) has examined Ihe 

 material of Violæ from the Færoes and has kindly sent me Ihe 

 following notes. 



176. Viola palustris L. 



177. V. silvestris (Lam.) Rchb., var. nov. rotiindato-crenata Becker; 

 Syn. V. Riviniana Ostenfeld, Bot. Færoes, I, p. 80, non Rchb. 



Folia plerumqiie rotiindato-cordata,subacuminata, rotiindato-crenata. 



Mr. Becker means that the Færoese form of the Silvatica-group 

 does not exactely match V. silvestris, var. Riviniana, but represents 

 an intermediate stage between V. silvestris, typica and var. Riviniana. 

 From his letter I quote: »it is especially noteworth with regard to 

 the inferior systematical rank of the V. Riviniana, that there occur 

 in islands forms which come more or less ncar to V. Riviniana or 

 may be identical with it and at the same time show the characters 

 of the true V. silvestris.« 



178. V. tricolor L., subsp. nov. faeroensis Becker. 



Folia ovato-rotnndata, plane crenata, ad apicem obtnsissima, par- 

 tim snbemarginata , ad basim in petiohim breviorem abrnpte vel sub- 

 abrnpte angnstata. Stipnlae hjrato-incisae, lacinia terminalis lata ob- 

 tnsa, laciniae laterales breves oblongae, obtusiusculae, introrsnm i — 2, 

 extrorsum 3 — A. Sepala late lanceolata. 



To this description Mr. Becker add the following nole: »The 

 form in question is characlerized by the broad-ovate leaves and by 

 the stipules pinnatifid to a smaller degree than the main form 

 (coming near to the stipules of Viola cornnta)«. 



In my list (1. c. p. 80) I had named the form »F. tricolor L. subsp. 

 gemiina Wittr., formå« and had mentioned, that it is perennial. I 

 should now like to name it: V. tricolor L., subsp. gemiina Wittr., 

 var. faeroensis (Becker), as it without doubt belongs to the subspecies 

 gemiina in Wittrock's sense. 



All the specimens from the Færoes are of this form. It is found 

 in the southern part of Str. (Kirkebo and Velbestad) and on Sando 

 (Sand, and other piaces according to Dr. Knud Poulsen), and it occurs 

 always around the houses and in the enclosed fields.
