Fam. XLII. VIOLACEAE. 
Mr. W. Becker of Hedersleben (Germany) has examined the 
material of Viole from the Fzeröes and has kindly sent me the 
following notes. 
176. Viola palustris L. 
177. V. silvestris (Lam.) Rehb., var. nov. rotundato-crenata Becker; 
Syn. V. Riviniana Ostenfeld, Bot. Faeröes, I, p.80, non Rchb. 
Folia plerumque rotundato-cordata, subacuminata, rotundato-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 near 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. faeroénsis Becker. 
Folia ovato-rotundata, plane crenata, ad apicem obtusissima, par- 
tim subemarginata, ad basim in petiolum breviorem abrupte vel sub- 
abrupte angustata. Stipulae lyrato-incisae, lacinia terminalis lata ob- 
tusa, laciniae laterales breves oblongae, obtusiusculae, introrsum 1—2, 
extrorsum 3—4. Sepala late lanceolata. i 
To this description Mr. Becker add the following note: »The 
form in question is characterized 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 cornuta)«. 
In my list (1. c. p. 80) I had named the form »V. tricolor L. subsp. 
genuina Wittr., forma« and had mentioned, that it is perennial. I 
should now like to name it: V. tricolor L., subsp. genuina Wittr., 
var. faeroénsis (Becker), as it without doubt belongs to the subspecies 
genuina in Wittrock’s sense. 
All the specimens from the Ferées are of this form. It is found 
in the southern part of Str. (Kirkebö and Velbestad) and on Sando 
(Sand, and other places according to Dr. Knud Poulsen), and it occurs 
always around the houses and in the enclosed fields.
