Fossil Floras of Cape Colony. 43 



siderably swollen at intex'vals ; the cast presents the appearance of 

 a transversely corrugated axis with l)road, transverse swellings and 

 intervening grooves. There are two branch-scars. The irregularity 

 in the diameter suggests a comparison with the root wood of recent 

 conifers. Somewhat similar casts are recorded by Goeppert •■' from 

 the Quadersandstein of Silesia as Ci/lindrites spongioiclcs. 



Specimens 32c, 33c, 34c, 36c, probably represent portions of coni- 

 ferous wood, but in the absence of petrified tissues an accurate 

 ■determination is out of the question. 



PLANT OF DOUBTFUL POSITION. 



Plate VI., fig. 14. 



The specimen represented in fig. 14 (332c) consists of two thick 

 bodies, consisting of a short stalk terminating expanding into a 

 semicircular head. In the lower part of the expanded head there 

 is a well-defined depressed area, bounded below by a straight line 

 and by a curved line above, which may be the scar of some 

 appendage. The surface is irregularly pitted. 



The collection includes a few other isolated bodies like the two 

 shown in the drawing (f.{/., 326c). 



Some detached scales figured by Fric and Bayer f from Lower 

 Cretaceous rocks of Bohemia as Dammara horcalis Heer bear a 

 resemblance to fig. 13, but I must leave them as portions of a plant 

 of uncertain position. 



III.— CONCLUSION. 



The following list includes all the species and genera recognised 

 in the Uitenhage Flora ; the localities from which the specimens 

 were obtained are added after each name : —
