{B. (?) angusti folia). In all probability neither of these 

 leaves is related to Eticalyftus. 



The secondaries spring from the midrib at an angle of 45*^ 

 to 50° and are approximately straight and parallel, about 

 1.5 mm. apart, some opposite, others irregular; intermediate 

 tertiaries give alternate branches to each secondary. The 

 venation is not characteristic of JSucalyptus , and resembles 

 somewhat that of Lmirofhyllum reticulatum Lesq., but our 

 specimen is a smaller, relatively narrower leaf. A second 

 specimen shows a marginal vein connecting the secondaries 

 about .5 mm. from the margin. 



STERCULIACEAE. 

 Sterculia Linn. Sp. PL 1007. 1753. 



Nearly one hundred existing species of the tropics of both 

 hemispheres. American fossil species are some seventeen 

 in number, distributed as follows: Potomac i, Cheyenne 

 Sandstone i, Raritan i, Island Raritan 2, Dakota 8, Creta- 

 ceous of British Columbia i, Denver i. Green River i. 



None have been recognized in the Atane beds of Green- 

 land, although one species occurs at Patoot. One species has 

 been recorded from the Island of Sachalin ; the genus is 

 present in the upper Cretaceous of Europe and some sixteen 

 species have been described from the European Tertiary de- 

 posits, although the American Tertiary is practically barren 

 of these plants. 



Sterculia Cliffwoodensis sp. nov. PI. 4.3./. 5.

It is to be hoped that more and fuller remains may be dis- 

 covered of this beautiful species. The present specimen in- 

 dicates a trilobed leaf with entire margin and decurrent base ; 

 lobes diverging at an angle of about 45° or less, with nearly 

 parallel margins and acute tips (?); the secondaries branch 

 at a wide angle and their tips are joined by rather straight 

 arches.
