In specimens about two inches in diameter, the areoles are two lines in length and one in breadth, and placed closely together. They are elliptical, acuminate, with central leaf scar, the form and markings of which could not be perceived. The leaves are thick at the base and short, slightly ascending, and then curving downward. The branches are slender, straight, and very uniform in thickness in the portions observed. This plant may be identical with the L. Chemungense of Hall, from the Devonian rocks of New York; but I am not aware that any specimens of that species hitherto observed show the leaf-scars or leaves; and, when these are obtained, should the present species prove distinct, I would name it L. Gaspianurrv\, Its characters, as above stated, are represented in figs. 3 a-c, * It is possible that some of the fragments, from the Devonian of the Thiiringerwald, included by Prof. Unger in his order RhachiopteridecB may be allied to Psilopkyton. (See Denkschr. Kais. Akad. Wissen. Wien, vol. xi. p. 139.) f L. (Sagenaria) Veltheimianum, another ancient and widely distri- buted species, resembles the above in the form of the areoles and position of the scars ; but the leaves and young branches diflFer, and my speci- mens show no median furrow in the areoles. L. nothum (Unger) also seems closely Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Natural History Society of Montreal.
