RAN ALES. 137 



Description. — Leaves orbicular-ovate in outline, 4 cm. to 10 

 cm. in length by 2 cm. to 5.5 cm. in width, petiolate. Apex 

 acute, slightly extended in one or two specimens. Base rounded 

 occasionally, usually pronouncedly auriculate. Petiole and mid- 

 rib stout. Secondaries few, 6 or 7 pairs, sub-opposite, campto- 

 drome. Texture smooth and subcoriaceous. 



This magnificent species is abundant and well preserved at the 

 Woodbridge locality and Marthas Vineyard and in the Magothy 

 formation of Maryland. Prof. Newberry was somewhat uncer- 

 tain as to its relationship with Magnolia and compared it with 

 Aristolochia, Polygonum and Toxyion. The latter is the only 

 genus which is at all suggestive, and it furnishes no instances of 

 auriculate bases, while this character of a base prevails in more 

 than one modern species of Magnolia. The outline, consistency 

 and venation, are all in accord in pointing to Magnolia as the 

 proper generic reference. This is one of those forms mentioned 

 from Marthas Vineyard by Prof. Hitchcock in his Geology of 

 Massachusetts published in 1841. 



Unfortunately the specific name had been previously used by 

 both Lamarck and Desvaux in 1783 and 1789. so that the fossil 

 species may well be renamed in honor of Dr. Hollick, who has 

 done so much in the elucidation of the Cretaceous floras in the 

 vicinity of New York. 



Occurrence. — Woodbridge. 



Collections. — N. Y. Botanical Garden.
