to the more slender branches of S. Kurrianum, would probably 

 be referred to Brachyphyllum, and it serves to illustrate the great 

 difficulty in attempting to discriminate between the various 

 provisional genera of fossil conifers. 



V. 23160. Fragment of a thick axis. Cf. Brachyphyllum obesum, 

 Heer. Ecclesbourne. Rufford Coll. 



V. 2303. The adpressed leaves very clearly defined. The 

 smaller branches appear to be identical with the fertile branch of 

 V. 2313 (PL XVII. Fig. 8). The long unbranched axis of this 

 and other specimens suggests an open habit of branching. 



V. 2303. Probably the same species, but the leaves are rather 

 less closely adpressed to the stem. Cf. Schenk, pi. xxxvii. fig. 5. 1 



V. 23033. A much branched specimen. Towards the lower 

 part of the thickest branch the leaves are seen to be shorter 

 and more crowded. Cf. also V. 2303, and Widdringtonites 

 Haidingeri, Ett., which Schenk has referred to S. Kurrianum. 



V. 2303c. Long branches with the leaves less clearly preserved. 

 Ecclesbourne. Rufford Coll. 



V. 2253. Portions of branches. The leaves showing longi- 

 tudinal stiiations, as in V. 2750 (PL XVII. Fig. 5). Eccles- 

 bourne. Rufford Coll. 



V. 2285. Probably 8. Kurrianum. Ecclesbourne. Rufford Coll. 



V. 2286. Cones with open scales, probably belonging to this 

 species. V. 718. Fragments of branches. Ecclesbourne. 



Rufford Coll. 



V. 2303rt. Slender branches with leaves rather less adpressed 

 to the stem than in some examples of the species. This form 

 suggests a passage to the more open leaves of S. Sternbergianum. 

 Cf.V. 2139 (PL XVI. Fig. 5). Ecclesbourne. Rufford Coll. 



? Sphenolepidium Kurrianum. 



V. 3343. T\vo large specimens. Slender branches given off 

 from an axis 3 cm. in diameter.
