A decided southern type; the next following locality ca. 65° and 

 only in the southmost part of the land fairly common.

XXVI. Callitrichaeae. 



The ('allilriche-&Tpecie& observed in Greenland occur near Ihe hol- 

 ders of shallow lakes, often hid among the stalks of Carex species. The 

 known localities lie rather isolated between 70° and 60°. As most of the 

 aquatic piants in Greenland they must be settled as decided southern 

 types. 



If the numerous pools and ponds in the gneiss-domaines of Green- 

 land were sufficiently investigated it wonld im donbt become apparent 

 that the Callitrichaceae and other small aquatic piants have a rather 

 continiious extension. 



All the CallUriche-nipGcieii, found in Greenland, flower and fructi- 

 ficate; hitherto they are only found in the lowland. They hibernate 

 enclosed in ice, because oi' their occurrence in shallow piaces in the 

 lakes, which freeze to ihe jjottom dnring winter.
