294 CHEIROLEPIS. 



a fairly short axis giving off the sporophylls at right angles. In 

 some of the cones the triangular distal ends of the sporophylls are 

 clearly seen. 



Oolitic Shale, Scarborough. 



40,519. A large specimen showing clearly the hahit of 

 branching, which agrees with that of Pagiophyllum peregrinum 

 as figured by Saporta. 



Other specimens: — ^r. 3575, 11,015, 13,524, 39,319, 39,325, 



39,327 (labelled by Bean Lyeopodites uncifolius). 



Genus CHEIROLEPIS, Sohimper. 



[Trait, pal. veg. vol. ii. p. 247, 1870.] 



This generic term was instituted by Schimper as a substitute for- 

 Brongniart's Brachyphyllmn in the case of certain forms which do- 

 not conform to the vegetative characters of the typical species, 

 B. mamillwre. The species referred to Cheirolepis agree, as regards 

 the form of the leaves, with WidAringtonia and Sequoia gigantea ; 

 the cone-scales are described as bearing solitary seeds. The plant 

 which Schenk ' named BrachyphyUwm Muensteri is the type species 

 of Schimper's genus. 



Cheirolepis setosus (Phillips). 



[PhilKps, Geol. Tories, p. 229, lign. 60, 1875.] 



(Text-figs. 53 a and b). 



1875. Brachyphyllmn setosum, Phillips, Geol. Yorks. p. 229, lign. 60. 



1890. Brachyphyllum setosum, Scheak, in Zittel, p. 287. 



1892. Brachyphyllum setosum, Fox-Strangways, Tab. Foss. p. 137. 



This species was instituted by Phillips in the third edition of his 

 Geology of TorhsMre, and defined as follows : — 



' ' Stem branching at obtuse angles, marked by alternate elongate 

 cicatrices ; leaves arranged round an axis, lanceolate, pointed, small, 

 short, crowded."
