122 PODOZAMITES. 



The specimen represented in Buckman's pi. ii. fig. 3 as Lilia- 

 lanceolata is, I have little doubt, specifically identical with Podo- 

 samites stonesfieldensis. The species named by Buckman Bensonia- 

 ovata (Geol. Chelt. p. 67) is not represented by a drawing ; it is- 

 described as being characterised by " leaves oblongo-ovate, entire, 

 with short stalk," ^ and may be Podozamites. In a paper on 

 Mesozoio Angiosperms Mr. Starkie Gardner alludes to the genera 

 ZiUa and Bensonia of Buckman, and speaks of them as being either 

 " Cycadaceous or too indistinct to be determinable." ^

 Slate, Great Oolite). 



The material is too fragmentary to admit of a satisfactory specific 

 diagnosis. The leaves or leafiets (if the plant is a Conifer, allied to- 

 Agathis, the term leaf must be used ; if it is Cycadean the term 

 pinna or leaflet is more accurate) are symmetrical about a median 

 axis, oblong-ovate in shape, entire, tapering somewhat abruptly to- 

 a narrow base and more gradually to the apex ; veins rather more 

 than 1 mm. apart, converging towards both the base and apex of 

 the lamina. 



Podozamites stonesfieldensis bears a fairly close resemblance to 

 Podozamites lanoeolatus, var. latifoUus, as figured by Schenk,' from 

 China, and to Geyler's Japanese species, P. Reinii} 



V. 3420. PI. XL Fig. 1. 



Leaf 7"5 cm. long ; the gap in. the middle of the lamina has- 

 probably been produced by tearing. Veins very well defined, 

 simple, or forked either close to the base or during their course 

 through the lamina.

V. 3468. PL XL Fig. 2. 



Possibly the original specimen figured by Buckman as Naiadea 

 ovata; 8 cm. long by3'6cm. broad; similar to V. 3420 (Fig. 1),. 

 but more complete. The base is slightly notched, as if originally 

 attached directly to an axis.
