In Dumfriesshire, Dolichopodids, a Muscid, and 2 hover-flies were recorded 

 (Scott-Elliot, ' Flora of Dumfriesshire,' p. 59). 



865. P. sylvestris Neck. ( = P. Tormentilla7W. and Tormentilla erecta Z.) 

 (Herm. Mtiller, ' Fertilisation,' pp. 233-4, ' Weit. Beob.,' II, p. 242 ; Loew, ' Bliitenbiol 

 Floristik,' p. 393 ; Schulz, 'Beitrage,' I, p. 35 ; Knuth, 'Weit. Beob. u. Bl. u. Insekt 

 a. d. nordfr. Ins.,' p. 234.) The flower mechanism of this species agrees with tha 

 of P. Anserina, but Hermann Miiller says that nectar is secreted more abundantly 

 and the anthers are only covered with pollen on their narrow external edges, and 

 not all over. Schulz states that the flowers, even of the same plant, are partly 

 homogamous, partly protogynous, and partly slightly protandrous. They vary in size 

 as do the stamens in number, and there is also considerable variation in the pistil.
