Berry: NOTES ON THE GENUS WIDDRINGTONITES 345 
apically (see FIG. 1 and 2). These leaves are not so short and 
broad as they appear in FIG. 1, 3, 4, 5, since in these specimens the 
entire leaf substance, except the cuticularized epidermis, has 
disappeared, and they are much flattened. The older leaves 
usually become elongated proximad and somewhat spreading and 
falcate distad, with a considerable decurrent base as shown in 
FG. 2. The leaves on twigs of the year are about 1.5 mm. in 
length while those on old twigs are about 2 to 3 mm. in length. 
Along their lateral angles the former bear minute spines, which 
increase in size and length distad (FIG. 3, 3a). The epidermal 
cells are small, about 0.025 to 0.0333 mm. in diameter, the longest 
diameter approximately parallel with the axis of the leaf, more or 
less regularly rectangular in outline except at the angles of the 
leaf and in the vicinity of the stomata, and they have very thick 
yellowish walls. The stomata are about 0.0333 mm. in diameter 
and show two thick, generally almost closed, nearly white, blunt- 
ended guard cells, without fixed orientation with respect to the 
different pairs or the major axis of the leaf. They appear to lie 
just beneath the surface of the epidermis. The guard cells are 
surrounded by a ring of five or six accessory epidermal cells, which 
are smaller than the regular epidermal cells, nearly uniform in size, 
and with their inner walls thinner than their outer. These appear 
to be on the same level as the ordinary epidermal cells. The 
Stomata are sparsely scattered over the major portion of the leaf 
but are usually absent or but sparingly represented in the distal 
half of the leaf. They are somewhat massed toward the base on 
the sides of the leaf j

version; due, I suppose, in some measure to the conditions 
attending fossilization, A form with uniformly slender and
