 ?Phyllites obscura Hollick in Newb., Ibid., 131, pi. 42, f. JJ, 

 1896. 



Description. — Leaves small, ovate in outline, about 3 cm. long 

 by 1.3 cm. wide, broadest near the middle and tapering equally 

 in both directions. Apex presumably acute. Base cuneate, acute. 

 Margin entire in the lower half of the leaf, coarsely dentate 

 above. Venation obscure, only a few^ pairs of thin secondaries 

 being visible. 



The form described by Hollick as Phyllites obscura is probably 

 an abnormal leaf of this species, and is here included under it 

 with a query. Species based on single specimens from unknown 

 localities and with affinities undeterminable are of little value 

 unless they serve as horizon markers, which this Phyllites does 

 not, so that it is desirable from every point of view to make the 

 foregoing disposition of it. 



Occurrence. — Locality unknown. 



Collections. — N. Y. Botanical Garden.
