Fossil Floras of Cape Colony. 43 



siderably swollen at intervals ; the cast presents the appearance of 

 a transversely corrugated axis with broad, transverse swellings and 

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

 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/Uiid rites spongioidcs. 



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 OP 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 {e.g., 326c). 



Some detached scales figured by Fric and Bayer t from Lower 

 Cretaceous rocks of Bohemia as Dammara borcalts 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 : —
