? Brachyphyllum sp. 
(Plate III, figs. 4, 5.) 
Some small fragments of vegetative coniferous shoots are referred* to 
the genus Brachyphyllum. They exhibit a series of small spirally-arranged, 
sharply-pointed leaves, closely appressed to the stem. The general appear- 
ance of the specimens shows a close resemblance to such a species as 
Sphenolepidium Kurrianum, 1 but in the absence of any association with cones 
it is perhaps advisable to adopt the more non-committal name, Brachyphyllum.

The specimens comprise portions of sterile coniferous fronds, and in the 
absence of characters which permit them to be included in any of the genera 
based on fertile specimens, they are referred to Halle’s genus Elatocladus. 
The branches exhibit numerous, long, linear leaves, up to about 4 cm. 
long and 2 mm. wide, pointed, and with a median vein. The arrangement of 
the leaves is spiral, as is clearly shown in cpiitc a number of specimens, though 
in the process of preservation on a flat surface the leaves have become 
arranged in two comparatively regular series. In a large number ( e.g ., Plate 
IV, fig. 1), the leaves are almost at right angles to the stem, while in others 
(Plate V, fig. 1) they are at a moderately acute angle. There is very little 
difference between these two, and it is not considered that they are sufficiently 
distinct to warrant specific distinction. In some, and more particularly in those 
in which the leaves are more inclined to the axis, the base of the leaf is 
quite markedly decurrent, and, as Seward suggests, 2 this form of leaf base is
