66 FLOKA OF SOUTHERN NEW YORK AND NEW ENGLAND. 



Magnolia longifolia Newberry. 



PI. XX, figs. 2, 3. 



Magnolia longifolia Newb.,Mon. U. S. Geol. Survey, vol. 26 (Fl. Amboy Clays), 1895 (1896), p. 76, pi. 55, figs. 

 3, 5;- pi. 56, figs. 1-4; Hollick, Trans. New York Acad. Sci., vol. 12, 1892, p. 36, pi. 3, fig. 9; Bull. Geol- 

 Soc. Am., vol. 7, 1895, p. 13; Annals New York Acad. Sci., vol. 11, 1898, p. 422, pi. 37, fig. 3; Fifty-fifth 

 Ann. Rept. New York State Mus., 1901 (1903), p. r50. 



Our fig. 2 is manifestly too fragmentary for satisfactory identification, but fig. 

 3 is apparently a small form of the species and is comparable with the leaf from 

 Woodbridge, N. J., doubtfully referred by Newberry to M. alternans Heer, a which, 

 however, can hardly be included in that species. 



Locality: Tottenville, Staten Island. Collected by Arthur Hollick. Specimens 

 in Mus. Staten Island Assn. Arts and Sci. 



Magnolia Isbergiana Heer. 



PI. XX, fig. 4. 



Magnolia Isbergiana Heer, Fl. Foss. Arct., vol. 6 (abth. 2), 1882, p. 91, pl. 36, fig. 3; Hollick, Bull. Torrey Bot. 

 Club, vol. 21, 1894, p. 60, pl. 178, fig. 4; Fifty-fifth Ann. Rept. New York State Mus., 1901 (1903), p. r50. 



This species is represented in our collections by the one specimen here figured, 

 which appears to be the only one thus far brought to light other than the single 

 type specimen from Greenland, figured by Heer (loc. cit.). The two figures are quite 

 similar, although the type shows a wider base, thus giving to the leaf a more pyrami- 

 dal shape than is indicated in ours. 



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

 Mus. New York Bot. Gard. 



Magnolia woodbridgensis Hollick. 



Pl. XX, fig. 7. 



Magnolia woodbridgensis Hollick, in Newberry, Mon. U. S. Geol. Survey, vol. 26 (Fl. Amboy Clays), 1895 (1896), 

 p. 74, pl. 36, fig. 11; pl. 57, figs. 5-7; Trans. New York Acad. Sci., vol. 16, 1897, p. 133, pl. 14, fig. 8; 

 Annals New York Acad. Sci., vol. 11, 1898, p. 60, pl. 3, fig. 2; Berry, Bull. New York Bot. Gard.-, vol. 3, 

 1903, p. 77, pl. 53, fig. 5; pl. 57, fig. 2. 



This specimen, although imperfect, is so exactly comparable with fig. 7, pl. 57 

 (Fl. Amboy Clays, loc. cit.), that they must be regarded as identical. It is the only 

 representative of the species thus far found within the insular area, although the 

 species is not uncommon in both the Amboy clays and the ClirTwood clay marls in 

 New Jersey. 



Locality: Balls Point, Block Island. Collected by Arthur Hollick. Specimen 

 in Mus. New York Bot. Gard. 



a Mon. U. S. Geol. Survey, vol. 26 (Fl. Amboy Clays), 1895 (1896), pl. 55, fig. 1.
