436 CONIFERALES INCERTAB SEDIS [CH. 



Bohemia specimen represented in fig. 804 the midrib is more 

 obvious and the leaf-bases have a more regular form. The branch- 

 ing is sparse and not pinnate. Velenovsky^ assigns some branches 

 to C. stenophylla but these may be younger forms of C. elegans. 

 Similarly C. squamosus^, as figured by Heer and other authors, 

 affords no satisfactory evidence of specific difference from C. elegans. 

 Impressions from the Atane beds of Greenland described by Heer* 

 as C. borealis have been compared by Schenk with Sequoia and also 

 referred by him to Torreya: there is no possibility of deciding the 

 precise systematic position of these and similar specimens. Ettings- 

 hausen* has described as Cunninghamites miocenica fragments of 

 shoots from Sagor in Carinthia bearing hnear leaves with a finely 

 serrate edge. 



ANDROVETTIA. Hollick and Jeffrey. 



This genus was instituted^ for Cretaceous fossils from Staten 

 Island superficially resembhng Fern leaves with a pinnate venation 

 and an irregularly lobed or incised margin. The leaf-hke fragments 

 are, however, stem-structures bearing minute scale-like leaves 

 attached to the edges and surface. In habit these phylloclades 

 agree with Phyllocladus , but on anatomical grounds the authors 

 of the genus regard it as Araucarian though the evidence is far 

 from convincing. 



Androvettia statenensis Hollick and Jeffrey. 



Some of the specimens show no indication of their phylloclade- 

 nature and, as impressions, would be identified as Fern pinnules 

 or referred to Thinnfeldia. Others, after bleaching in chlorine- 

 water, showed a fairly stout 'vascular axis giving off simple or 

 forked branches at an acute angle; small decurrent leaves free 

 only at the apex occur on the margins of the shoots (fig. 806, A, B). 

 In a few cases the phylloclades bear short axillary branches with 

 immature cones, possibly microstrobili. 



There are three vascular cylinders in the section reproduced in 

 fig. 806, C, and in the narrow wings of the 'lamina' there are the
