Walchia dawsoni and Walchia hypnoides from Lodeve, 
France. Kidston remarked, ‘‘probably this species is only 
a smaller form of Walchia piniformis.”’ 
I have compared the Prince Edward Island plant 
with eight specimens from Lodeve, France (five attrib- 
uted to W.hypnordes and three to W.piniformis) identi- 
fied by Bronn, Heer, Lesquereux, and de Koninck. 
The American species is distinct ‘fon account of the 
very steadily tapering and blunt appressed leaves of the 
plant from Lodeve, whereas the leaf of the tree from the 
Permian of Canada, as shown in detail by Dawson, is 
much more slender, tapering mainly toward the tip, 
which is, however, slender, acute, and more strongly 
upturned near the apex.’’ (White loc. cit.). 
These characters are constant in the material at my 
disposal, consequently I concur with the opinion of 
David White that is is improbable that Walchia dawsont 
will be proven to be identical with Walchia hypnoides. 
However, Dawson’s several specimens identified as Wal- 
chia gracilis do represent a single species, which must be 
known as Walchia dawsoni White. Recently Henry 
Donner has sent me a specimen of Walchia from the 
supposed Permian of Colorado. The fragment is insuf- 
ficient for certain identification. It agrees well with Wal- 
chia dawsoni except that the needles are more robust and 
more distant. I doubt if this is a specific difference. 
In North America, Walchia is abundant in the Low- 
er Permian. Lesquereux identified several species from 
Fairplay, Colorado.’ I.C. White’ reported the genus from 
the Wichita (= Permian) of Texas, and David White’ 
reported many specimens from Texas, Kansas, Oklaho-
