In Dumfriesshire, Apis, 4 humble-bees, an Empid, 8 hover-flies, and 4 Muscids 

 have been recorded (Scott- Elliot, 'Flora of Dumfriesshire,' p. 32). 



509. H. hirsutum L. (Herm. Miiller, ' FertiUsation,' pp. 140-1 ; Kirchner, 

 'Flora V. Stuttgart,' p. 327.) — This species has somewhat smaller flowers and fewer 

 anthers than the last. As Hermann Miiller explains, the three groups of anthers 

 are therefore separated by wider spaces, so that automatic self-pollination is prevented 

 in the open flower. It regularly takes place, however, by the closing of the flower 

 even before the end of anthesis. The result, according to Hermann Miiller, seems 

 to be complete fertility. 



Visitors. — In Dumfriesshire, 2 humble-bees, an Empid, 3 Muscids, and a 

 hover-fly have been recorded (Scott-Elliot, ' Flora of Dumfriesshire,' p. 34).
