DESCRIPTIONS OF SPECIES. 89 



of the leaves in the genera Gyminda, PteroceJastrus , and Maytenus, although in most 

 of these the secondary nerves are only occasionally opposite.

El^odendron strictum, n. sp. 



PI. XXXIII, fig. 6. 



Leaf linear-ovate-lanceolate in outline, crenate-dentate above, entire below, tapering to a slightly rounded 

 wedge-shaped base; secondary nerves in pairs, almost straight, forming acute angles with the midrib, extending 

 upward and giving off nervilles from their outer sides which extend to the marginal dentitions. 



This leaf is characterized by the almost straight secondary nerves, arranged in 

 pairs, thus differing from any other described species.

ELiEODENDRON sp. 



PI. XXXIII, fig. 7. 



Celastrophyllum Benedini Sap. et Mar., Ilollick, Bull. Torrey Bot. Club, vol. 21, 1894, p. 58, pi. 177, fig. 4. 



This specimen probably represents a new species, but it is too imperfect to serve 

 as a basis for satisfactory description. It is somewhat suggestive of Elseodendron 

 speciosum Lesq.,'' but the dentition is much finer. 



Locality: Glen Cove, Long Island. Collected by Arthur Hollick. Specimen

Family ACERACE^E. 



Acer minutum HolHck. 



PI. XXXIII, fig. 14. 

 Acer minutus Hollick, Trans. New York Acad. Sci., vol. 12, 1892, p. 35, pi. 3, fig. 6. 



This is the only leaf which could be referred to a maple thus far found in the 

 insular flora, and the figure is a reproduction of the figure of the type specimen. 

 Winged seeds which apparent^ belong to the genus occur at Gay Head and in the 

 Amboy clays of New Jersey, however, and it is possible that these ra&j have come 

 from the same species of tree as the leaf, but thus far we have not found them asso- 

 ciated together.

Fruit of Acer sp. 



PI. XXXIII, figs. 12, 13. 



These winged seeds are ^ery much like those which Newberry calls Acer amhoy- 

 ense,^ from the Cretaceous of New Jersey, and they probably belong to the same
