stracture, that this hardly needs pointing out. As far as my 

 knowledge extends, the plant comes most near to Canninghamia 

 in the structure of its cones — that is in the arrangement of the 

 seminiferous scales, in the presence of the minute bract, in the 

 attachment and position of the ovules and in the shape ol" the 

 seed, wing, albumen and embryo. But it differs from the latter 

 by the absence of the secondary squama and the number of the 

 ovules which is decidedly two in each scale. These two different 

 points and the even more quite different vegetation of the plant 

 do not allow us to bring it into Cunninghamia. A new generic 

 name may therefore be better established for this })lant, rather 

 than place it in any inadequate genus we have at present. The 

 technical description of this new Conifer will l)e laid before the 

 Linnean Society. 13. Hayata.
