more in favor of the name here adopted. I am not aware that 

 either of the above species have yet been identified from the 

 New Jersey clays, but the indications are that they are not 

 uncommon on Long Island.

LiRIODENDKON SIMPLEX, Newb. 



PI. V. f. 1-5 and PI. VII. f. 2, 3. 



Under this specific name I have included a variety of forms 

 referable to the one genus. Dr. J. S. Newberry, in his first 

 description of the species, (Ancestors of the Tulip Tree, Bull . 

 Torr. Bot. Club, XIV. 1-7, Ph LXL, LXII.), called attention to 

 the great vai'iation in this and allied forms {L. primaeviim, 

 Newb.; L. semi-alafuni, Lesq. ; L. Meekii, Heer; Sapolacilcs 

 retiisKs, Heer; S. Haydeni, Heer; Leguminodtea Marcouanu>(, 

 Heer; Phyllifes obcordatuA, Heer, etc.). Subsequently, in the 

 manuscript of the Flora of the Amboy Chxys, he decided that 

 the forms originally described by him, under the name Lirioden- 

 dron simplex, were genericaliy distinct from Liriodeudron, and a 

 new genus, Z/iViorf<??i6?ro/:>.9i>, was founded, to include them. The 

 species was also split into two groups, the broad forms being 

 called L. simplex, and the narrower ones L. angustifoHus. These 

 latter are represented, in our specimens, by f. 3, PI. V. Similar 

 forms were also figured by me from Staten Island. (Paheon- 

 tology of the Cretaceous Formation in Staten Island, Trans. 

 N. Y. Acad. Sci. XI. PI. II. f. 3 and 6.) The broad forms are 

 b}' far the commonest, and are indeed the most abundant of all 

 the cretaceous leaves thus far found either on Staten Island or 

 Long Island, and are likewise so reported by Mr. David White 

 from Gay Head, Martha's Vineyard. (Cret. Plants from 

 Martha's Vineyard, Am. Journ. Sci. XXXIX. (1890) 93-101, 

 PL II.) Intermediate forms are figured on PI. V. f. 5 and 

 PI. VII. f. 3. Until such time as the Flora of the Amboy Clays is 

 published, I have thought it best to retain Dr. Newberry's only 

 l)ublished name for these leaves. 



All the specimens here figured are from Glen Cove, L. I. 



Sapindus Moruisoni', Lesq.
