emphasizes the lack of decurrence of the leaves, a Sequoia character, and 
this is strictly true, but the petioles are distinctly so on the terete twigs. 
This author also expresses the opinion that this species is indistinguishable 
from the existing Taxodium distichum. This is hardly correct, for although 
the two are naturally similar, I find no difficulty in differentiating them. 
Taxodium occidentale is not associated with Taxodium dubium in 
the occurrence at Newhykulston creek, but it is abundant and associated 
with the still more abundant remains of the latter at Joseph creek. 
Pinus trunculus Dawson 
Plate X, figures 4, 5 
Pinus trunculus Dawson, Trans Roy. Soc., Can., vol. 8, sec. 4, p. 78, fig. 5, 
1891; Penhallow, Rept. Tert. PL Brit. Col., p. 69, figs. 24-28, 1908. 
This species has been previously recorded from Stump lake, Quilchena, 
Tulameen, Horsefly, and Tranquille rivers, B.C., from beds that have been 
referred to the Oligocene and Miocene. Penhallow gives a number of 
excellent figures of this species in which he finds that the leaves were 
in fascicles of five. Dawson’s type apparently had the leaves in threes 
as is the case in the specimen figured by me. Associated with the latter 
are both short and broadly-winged seeds like that figured by Dawson, 
and elongate narrow-winged seeds like some of those figured by Penhallow. 
It would seem that two species — one with 5 leaves to a fascicle and another 
with 3 leaves to a fascicle — had been confused under this name, but in 
any event the present occurrences are identical with the material to which 
Dawson first applied the name Pinus trunculus. 
The present material in this species comes from Joseph and Darlington 
creeks.

1868; Penhallow, Rept. Tert. Pl. Brit. Col., p. 68, figs. 20-23, 1908. 
I have followed Penhallow’s treatment of similar material from 
Quilchena, B.C., in referring the cone scales found at Joseph creek to 
this Arctic species, which they closely resemble, although I see no reason 
for supposing that they do not belong to the same botanical species as 
furnished the associated seeds and leaves that I have referred to Pinus 
trunculus Dawson.

Grass or sedge-like remains of this sort are of slight value and exhibit 
few, if any, diagnostic features. Blender, finely longitudinally veined 
fragments in the collection from Newhykulston creek appear to represent 
this or a closely related species.
