DESCRIPTION. 



P.—E. (?) angustifolia Newberry. 



Op. cit., p. Ill, with PL xxxii, figs, 1, 6, 7. (1895.) 

 Following is the original description : — ■ 



Leaves long linear, pointed above, attenuated or rounded below, from 10 cm. to 15 cm. long, 8 mm. 

 to 12 mm. wide, margins entire; nervation rather crowded, midrib slender, side branches numerous j 

 leaving the midrib at an acute angle and forming a festoon close along the margin. 



These leaves apparently belong to the same genus as those that have been called Eucalyptus by 

 Heer in his ' : Flora Fossilis Arctica," vol. vi, Abth. ii, pp. 93, 94, plate xlvi, figs. 12-14. The general form 

 of the leaf is similar, and the peculiar nervation — that is, numerous lateral nerves uniting to form a 

 continuous festoon closely parallel with the margin — is essentially that of Eucalyptus. Professor Heer 

 feels strengthened in his reference of leaves having this nervation to Eucalyptus by finding in company 

 with them what he regards as the fruit of Eucalyptus; but in my judgment the examples he gives of this 

 fruit (op. cit., loc. cit., and pi. xlv) are rather detached scales of the cone of some conifer, and probably 

 generically identical with the cone scales which he has called Dammaraborealis (op. cit., pp. 54, 55, pi. xxxvii, 

 fig. 5). The fruit of Eucalyptus is a pyxis or urn, circular in section, and with a lid; but in the large 

 number of specimens of organisms which I have found in the Amboy Clays, and have considered identical 

 with Heer's so-called Dammara, I have looked in vain for any evidence of a separation between the summit 

 and base, and have regarded them as the exposed and buried portions of cone scales. (See supra, pp. 54, 55.) 



The leaves now under consideration differ from those I have considered as identical with Heer's 

 Eucalyptus Geinitzi in this, that they are much longer and narrower and more attenuated at base and 

 summit. 



Locality.— South Amboy. 



Note. — For representatives of fruit of Dammara microlepis Heer, and Eucalyptus Geinitzi Heer, 

 from El. Foss. Arcl., see pi. x, figs. 9, 10, of this monograph. A.H. (Hollick). (Op. cit., p. 111.) 



D. Eucalyptus Geinitzi Heer, Fl. Foss. Arct., Vol. vi, abth. i, p. 93, PL xlvi, 

 figs. 12c, 13. 



Following is a description, with PL xxxii, figs. 2, 12, 15, 16* : — 



Leaves lanceolate, pointed above and below, 10 cm. to 15 cm. long by 15 mm. to 25 mm. wide, 

 margins entire; nervation open and flexuous, lateral nerves numerous, arched upward, connecting above 

 to form a festoon parallel with the margin, united by tertiary branches which divide the spaces between 

 them into square or oblong areoles. 



A considerable number of leaves answering to the description given above occur in the Amboy 

 Clays, and so nearly coincide with those figured by Heer under the name of Eucalyptus Geinitzi that I 

 have been compelled to consider them the same. The plan of nervation is essentially the same as that of 

 the other leaves I have grouped in the same genus, bu£ the nervation is more open and the leaves are 

 broader and larger. 



One of the supposed fruits of this species as figured by Heer is represented on Plate x, fig. 10, of 

 this monograph. (See supra, p. 46.) 



Localities. — Woodbridge, Sayreville, &c. 



* I doubt very much tha Ifig 1 6represents a specimen of this species, or even genus. It is unquestionably so 

 included, however, in Dr. Newber \'smanus;ript. A.H. (Hollick). (Op. cit., -p. 110.)
