68 THE FLORA OF THE AMBOY CLAYS. 
Sauix Newserryana Hollick n. sp. 
Pl. XIV, figs. 2-7. 
Leaves 10™ to 15° in length by 1™ to 3°" in width, lanceolate in out- 
line, elongated at summit, wedge-shaped at base, petioled; finely and 
sharply serrate; nervation fine, invisible on the upper surface, sharply defined 
in the impression of the lower; medial nerve straight and strong; lateral 
nerves given off at an angle of about 45°, numerous, inosculating at their 
summits; intervals between them filled with a polygonal and relatively 
coarse network. 
These leaves are referred to Salix with doubt, although they possess 
the outline, nervation, and margins of some of the willows of the present 
day. The general appearance is somewhat like that of Celastrophyllum 
angustifolium, described in this monograph, but in that species the margin is 
crenulate, while here it is finely and sharply denticulate. Professor Heer 
enumerates a number of species of Salix from Greenland, but they are from 
the Tertiary and none trom the Cretaceous beds. 
Localities: Woodbridge, Sayreville, South Amboy. 
Saux sp.? 
Pl. XLII, figs. 6-8. 
Leaf ovate-lanceolate in outline, 3° long by 1° or more broad, entire, 
tapering to a point above, rounded below, short petioled; nervation obscure. 
These leaves have the general appearance of Salix Reana Heer, as 
figured in Flora Fossilis Arctica, Vol. VII, Pl. LXIX, fig. 2, but the nerv- 
ation in our specimens is too indistinct for definite comparison. ‘They 
also closely resemble Salix Hayei Lesq., although considerably smaller, as 
figured at Pl. ITI, fig. 7, in the Flora of the Dakota Group. The affinity of 
this latter species with S. Reana is noted by Professor Lesquereux, and I 
have thought it probable that all three species may have to be ultimately 
‘Dr. Newberry, in his manuscript, called this species Salix denticulata, a name which is preoccu- 
pied by a Miocene species of Switzerland described by Heer. It was therefore decided to name the 
Amboy species after Dr. Newberry.—A. H.
