Confirming the record of this species from the Puget group at Burrard 
inlet, there are two unmistakable specimens in the collection from that 
place. The species is a wide ranging one said to occur as early as the Fort 
Union of Yellowstone park, and common in the Green River, Lower 
Clarno, and Claiborne, as well as the Eocene of the Wilkison coal field of 
Washington (state).

This exceedingly interesting species is represented by several char- 
acteristic specimens in the collection from Joseph creek. Its wide dis- 
tribution serves to correlate the Arctic floras of Europe, Asia, and North 
America. It has been recorded from the Lance and Fort Union formations 
of the United States, but is specially characteristic of the later and more 
northern Upper Eocene, where it has been recorded from Tulameen, 
Horsefly, and Similkameen rivers, B.C.; from the Mackenzie basin; from 
Porcupine creek and Great valley, Alberta; from the isle of Mull; Green- 
land; Alaska; and Sakhalin island. The fossil species is exceedingly 
close to the existing species which survives in a limited region in eastern 
Asia, although commonly planted as an ornamental tree and hardy through- 
out the North Temperate zone.

This is another Tertiary form which, like the contemporaneous Taxo- 
dium and Glyptostrobus, ranged pretty well over the northern hemisphere. 
Its superficial resemblance to Taxodium renders many records extremely 
uncertain, but it may readily be distinguished by its decurrent leaves 
which are not contracted to a distinct, if short, petiole, as in Taxodium, 
and it does not commonly occur in the form of deciduous twigs as does 
Taxodium, but as branched fragments. 
It is a member of the Kenai flora of Alaska, and has been recorded 
from the following localities in Canada: Red Deer river and Porcupine 
creek, Alberta; Bear river, Mackenzie valley, Yukon; Blackwater, Simil- 
kameen, Horsefly, Finlay, and Omineca rivers, B.C. It is also common in 
the Upper Eocene of Greenland, Spitzbergen, Sakhalin island, etc. In the 
present collections it is contained in that from the Puget group at Kitsilano, 
where it is abundant and characteristic, and in that from Joseph creek. 
1 It is deemed unnecessary in this contribution to give the synonymies of species in which these are extensive, 
or, in fact, any citations not demanded by the subject matter. The aim is to make the work useful so that the 
citations, as in the above case, may not be the oldest, but refer to works in which there are excellent figures.
