294 CHEIEOLEPIS. 



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 habit of 

 branching, which agrees with that of Pagiophyllum peregrinum 

 as figured by Saporta. 



Other specimens: V. 3575, 11,015, 13,524, 39,319, 39,325, 



39,327 (labelled by Bean Lycopodites uncifolius). 



Genus CHEIROLEPIS, Schimper. 



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



This generic term was instituted by Schimper as a substitute for 

 Brongniart's Brachyphyllum in the case of certain forms which do 

 not conform to the vegetative characters of the typical species, 

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

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

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

 which Schenk ' named Brachyphyllum Ifuensteri is the type species 

 of Schimper's genus.

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



1890. Brachyphyllum setosum, Schenk, 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 Yorkshire, and defined as follows : 



" Stem branching at obtuse angles, marked by alternate elongate 

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

 short, crowded."
