PerrcE® has studied the dissemination and germination of the seeds of 
Arceuthobium occidentale on the Monterey pine (Pinus radiata) of Californ'a. 
The structure and mechanics of the exploding fruit are described in detail; and 
the seeds were observed in the laboratory to be thrown fifteen feet, sticking 
whatever they struck. The so-called seeds, by the way, are closed 
the inner part of the ovary. The field observations indicate that the pies . 
of seeds strike the leaves of the pine, either of the tree on which they grow * — 
one near by. In germination the root is negatively phototropic and not very 
Sensitive to contact. When growth is blocked by some obstacle the root ni : 
a thick foot-like holdfast, into which the material in the upper end of the embryo ;
