SAPIXDALES. 179 



Description. — Leaves small, 3 cmi. to 4 cm. in length by 1.4 cm. 

 to 3 cm. in breadth, ovate to broadly spatulate in outline. Apex 

 rounded more or less broadly. Base narrowed and decurrent. 

 Margins entire below, dentate above, the teeth usually confined 

 to the apical third of the leaf. Midrib usually somewhat curved, 

 giving the leaves an unsymmetrical appearance. Secondaries 

 6 tO' 8 pairs, branching from the midrib at an acute angle, curv- 

 ing slightly upward, camptodrome. 



The more narrow forms were separated from the broader 

 form's by Prof. Newberry, both being given specific rank, al- 

 though it seems obvious that they are the variable extremes of 

 a single species, and that not an especially variable one. They 

 approach rather closely to^ Celastrophylliini Brittoniamim Hollick, 

 but are readily distinguishable by their less symmetrical shape 

 and narrower base, their coarser and less numerous teeth, and 

 their usually more numerous, more ascending, and straighter 

 secondaries. 



No localities for this species are given in Prof. Newberry's 

 Monograph. Later collections show it tO' be abundant in the 

 upper Raritan at South Amboy.
