crowded leaves, and small, oblate, spheroidal cones. It has been referred 
to a variety of genera and is very ambiguous from a botanical standpoint. 
As it stands in the literature it has a very wide range, being common in 
the Wealden, throughout the Lower Cretaceous of Portugal, and with a 
similar geologic range in the Potomac Group. It is probably present in 
the Kome beds of Greenland where it masquerades as a Sequoia or 
Glyptostrobus. 
Remains that apparently represent this species are present in the 
Lower Blairmore at localities CH6 and DAI.

This is one of the typical and well-marked species of Cretaceous Sequoia. 
It was described originally from material from the Kome beds of western 
Greenland, and was subsequently identified by Dawson from a number of 
supposed Kootenay localities in British Columbia and from the Kootenay 
of Montana. It is not uncommon in the Bull Head Mountain sandstone 
of British Columbia. It has been recorded by Kryshtofovich 1 from the 
Upper Cretaceous of the island of Sakhalin, but as he gives no illustrations 
and species of Sequoia show many convergent features I regard the identi- 
fication as extremely unlikely, although not impossible. 
Localities in the Lower Blairmore CH5 and CH7. 
Genus, brachyphyllum Brongniart (?) 
Brachyphyllum sp. 
Doubtfully represented by obscure, relatively slender twigs at locality 
CH7 which may simply represent the thicker branches of the Lower 
Blairmore conifer that I have referred to Athrotaxopsis grandis. Such thick 
old branches would tend to have the leaf scars shortened until they would 
resemble the rhomb oidal leaves of this genus. 
Brachyphyllum is said to appear in the geological record in the 
southern Permian, but it is especially characteristic of the Jurassic and 
Lower Cretaceous, surviving into the Upper Cretaceous and gradually 
dying out during that time.
