fruits being quite like that of the fruits of the wildgrowing trees in 

 Norway. The list of weeds says, that the fields at that time were 

 very impure; with exception of Galeopsis tetrahit which has immigrated 

 earlier^ the weeds are introduced to Norway together with the plant- 

 culture. C. H. Ostenfeld.

 kreises der Poteiitllla venia L. ex p.) Lehm, et auct. 

 plur., mit besonderer Berücksichtigung der gott- 

 ländischen Formen. (Arkiv för Botanik. Bd. IV. No. 2, 4. 

 III. 1905. p. 18. 4 plates.) 



Through studies in living material the author has found several 

 distinct forms of Potentilla venia (L. ex p.) Lehm. (= P. minor Gilib.) 

 and has cultivated them. He describes the different kinds of hairs which 

 occur in the plants in question and which among the Potentillae are 

 taken as good characters ; further he points out that the shape and 

 colour of the petals are constant character of high systematical value. 

 Then he describes the forms of P. verna: the mainform with a forma 

 concaviflora K. Joh., the var. parviflora Lehm., the var. erythrodes K. Joh., 

 the var. obcordipetala K. Joh., the subspecies croceolata K- Joh, At last 

 he enumerates the hybrids of P. verna. C. H. Ostenfeld.
