1. Populus rhomboidea (Lsqx.). Leaves rhomboidal, with the mar 
gins irregularly toothed above, and entire near the slightly eee base, 
Later: — nerves diverging at an acute angle like 
ones, and ascending to both corners of the rhomb of the leaf, ‘al strongly 
marked with scarcely visible percurrent veinlets. It is much like Popu- 
lus repando-crenata of Heer, differing only by the leaves somew 
broader and by the undulations and teeth a little deeper. The us 
mutabilis with its numerous varieties is a characteristic plant of the upper 
Molasse or Miocene of Europe, especially found in the upper strata of 
Oeningen. (Nanaimo). 
2. Salix es (Lsqx.). Leaves large, patirie pointed, serrulate, 
rounded at the base. Secondary nerves in acute angles with the medial 
nerve, nearly straight and numerous. Subdivisio ons of the nerves invisi

ee (Heer) of the Miocene of Europe. eerie” pels lg
