JURASSIC PLANTS FROM CROMARTY AND SUTHERLAND, SCOTLAND. 875 
scale. There are three similar elevations on the scale to the right of the apex of the 
cone (text-fig. 2, B, s,s). The spaces, the filling material of which forms the elevations, 
s, are probably resin-cavities enlarged by decay ; they correspond to the clefts contain- 
ing an amber-like substance to which attention has been drawn by Newserry * and 
other authors in the case of American examples of scales referred to Dammara. 
Similar patches of resin form a conspicuous feature in scales of the same form from 
Greenland. f 
One of the scales, cut in an approximately median plane, shows (text-fig. 3) a 
large cavity and two dark patches of resinous (?) cells at s, s; above the cavity is a 
vascular strand (vb). The distal end is characterised by a short and broad apical

portion in the base of which is a continuation of the vascular strand (vb). The two- 
pronged projection from the upper surface of the scale (/) is regarded as a ligular 
outgrowth ; below this are irregular spaces. ‘The depression on the adaxial side of the 
outgrowth we believe to have been occupied by a seed. Sclerous cells are abundant 
in the ground-tissue. 
Forma 8. (Text-fig. 2, C.) 
This specimen, which, like forma a, is preserved in a weathered calcareous nodule 
from Kathie, has a length of approximately 9 cm., and is 4 em. at its broadest part. As 
the preservation appears to be very imperfect, no sections have been prepared. A thick 
axis bears broad and deep sporophylls arranged in a lax spiral. The uppermost
