JURASSIC PLANTS FROM CROMARTY AND SUTHERLAND, SCOTLAND. 877 
with numerous thick-walled fibres. Sporophyll IV., shown on a large scale in fig. 14, 
has lateral wings and a broadly rounded ridge in the middle of the upper face (a, fig. 
14); the dark line at the sides of the area a is the result of crushing of the paren- 
chymatous tissue. The thick fibres or idioblasts, f; are clearly seen in the more highly 
magnified photograph of the area a reproduced in fig. 15. An almost continuous 
line of vascular strands is seen stretching across the cone-scale at v, fig. 14; the xylem 
appears to be normally orientated, the protoxylem being next the upper surface ;

but the preservation is very imperfect. Below the vascular strands is a median space, 
and some palisade parenchyma occurs next the lower surface similar to that shown in 
fig. 16. 
Cone-scale III. (text-fig. 4, A) is similar to IV., but the ridge in the middle of the 
upper face is much more prominent. In cone-scale VI. also the structure of the ground- 
tissue is very clearly preserved; the line of vascular bundles is seen stretching across 
the scale, and a space is present like those in scales III. and IV. 
Cone-seale V. (text-fig. 4, A) is cut obliquely ; there is a large space i. and three 
smaller spaces separated from it by some crushed and partially destroyed vascular 
tissue, v, some of which appears to have a concentric arrangement. This scale is
