Fossil Floras of Cape Colony. 55 



Museum Collection (V. 4197) ; it is clearly identical with the South 

 African examples, but the details are less distinct in the specimen 

 than in the published figure. 



Plato VII., fig. 1 (21e). 



Branched piece of frond ; the unbranched portion shown in the 

 figure has a length of 11-5 cm. and is incomplete distally. The longest 

 segment is 1'5 cm. long and 6 mm. broad. The pinnules show very 

 clearly the slightly divergent and forked veins and the leathery 

 texture of the lamina. 



Plate VII., figs. 8, 8a (45e). 



Preserved as a clearly defined brown impression with numerous 

 fragments of pinnae with pinnules varying considerably in size ; 

 the figured segments show the midrib and lateral veins very clearly. 



Plate VII., fig. 7 (477d). 



An indistinct impression in oxide of iron on sandstone. The 

 linear pinnules are confluent at the base, forming a narrow wing to 

 the rachis. A midrib is seen in the lower part of some of the 

 segments, also oblique secondary veins. Associated with fragments 

 of pinnae bearing the shorter and broader type of segment. 



Plate VIII., fig. 7 (22e). 



A piece of a pinna with larger segments (1'5 cm. x 10 mm.) ; also 

 a forked pinna with smaller pinnules. 



Plate VIIL, fig. 8 (d). 



A specimen on a piece of shale from Cyphergat showing much 

 smaller pinnules ; associated with other specimens of the type 

 represented in fig. 1, pi. vii. 



Plate IX., fig. 7 (A). 



A few epidermal cells of a small leaflet of Thinnfeldia odontop- 

 tcroides, showing the slightly wavy form of the walls, and four cells 

 surrounding a stomatal pore. The narrower central part of the pore 

 is bounded by the remains of dehcate cell membranes with thickened 

 borders which possibly represent cuticular ridges of the guard cells. 

 The appearance of the stomata suggests that the guard-cells are 

 slightly sunk.
