50 FLORA OF SOUTHERN NEW YOEK AND NEW ENGLAND. 



Aments of populus sp. 



PL VII, figs. 16-18. 



"Ament * * * probably a Salix or a Poipulus," Hollick, Bull. Torrey Bot. Club, vol. 21, 1894, p. 63, pi. 

 180, fig. 6. 



These rather questionable remains were found at both Gay Head and Glen Cove, 

 and a few additional fragments are also included among the specimens not figured. 

 They apparently represent dismembered catkins or aments and may be compared 

 quite satisfactorily with those of Populus, although they have not been found closely 

 associated with any leaves of that genus.

Salix membranacea Newberry.

Although these specimens differ considerably in size and also in shape, these 

 differences are no greater than are shown in Newberry's figures (loc. cit.) . Our fig. 10 

 is comparable with Newberry's figs. 6 and 8 and our fig. 23 with Newberry's figs. 5, 7. 

 I am inclined to think that two species may be represented by these two forms, but 

 as it was Newberry's evident intention to include them under the one species I have 

 done the same, although it is probable that our fig. 23 may ultimately be relegated 

 to S. mattewanensis Berry , loc. cit.

Salix cuneata Newberry.

 " Salix, sp.?" Hollick, Trans. New York Acad. Sci., vol. 12, 1892, p. 32, pi. 2, fig. 16. 

 Myrica longa Heer, Hollick, Annals New York Acad. Sci., vol. 11, 1898, p. 419, pi. 38, fig. 6. 



It is with some hesitation that I have decided to group these three specimens 

 together under this species, as they present some slight differences in the angle of 

 nervation and in their basal outlines, but similar slight differences may also be seen 

 in the two specimens figured by Newberry. It may also be noted that our speci-
