leaf-scar rings on it. Growing out from the dwarf shoot from the axil of the third- 
year ring of leaves there was a very small secondary dwarf shoot with six or seven 
small leaves on it. Such an appearance is quite understandable, because, if a dwarf 
shoot under suitable conditions can become a long shoot upon which dwarf shoots 
are subsequently formed, there is no reason a priori why secondary dwarf 
shoots should not appear on an ordinary dwarf shoot. But the branching of 
dwarf shoots in the Abietineae has not often been described. 
Special thanks are due to Sir Frederick Moore, of the Glasnevin Gardens, 
Dublin, who has placed several Larch trees entirely at the writer’s disposal.
