34:4 J. S. Newberry — B 'Acetic Plants from Honduras. 



This plant, like the preceding, was briefly characterized in 

 the Transactions of the E"ew York Academy of Sciences, vol. 

 vii, p. 114. It differs from Z. Bolheri in its shorter and 

 broader pinnules and in its nervation, which is partly radiate. 

 Better specimens than any yet obtained are needed before a 

 complete description of it can be written, or its generic rela- 

 tions be accurately determined. Some of the pinnules appear 

 to be attached by the entire base, while in others the attach- 

 ment is only by the central portion and the nervation is more 

 distinctly radiate. Like the preceding species it is only referred 

 to Zamites provisionally, and it is almost certain that they will 

 ultimately be assigned to different genera. 



In general aspect this and the preceding species closely 

 resemble Btilophyllum acutifolium and Pt. Cutchense Morris, 

 Fossil Flora of India, but are distinctly separated from them 

 by the mode of attachment and the nervation. 



It is evident that still another review of fossil cycads is 

 needed although we have had so many already, but this is no 

 place for it and it will be sufficient for our present purpose to 

 refer the plants described above to Zamites, as Heer has done 

 those with which I have compared them, leaving their final 

 generic titles to be decided hereafter, by the study of more 

 complete specimens. 



Otozamites linguiformis\ n. sp. Figs. 9, 10. 



Fronds strong ; rachis striate ; pinnules one to two inches in 

 length by half an inch in width, crowded, sometimes overlap- 

 ping ; below issuing from the rachis at right angles, above 

 obliquely; outline long-tongue-shaped ; summits evenly rounded, 

 bases unequally cordate, attached by a single point at the 

 center ; nerves numerous, fine, simple or forked, radiating 

 from the center of the base to all parts of the margin. 



This handsome species is allied to, though quite distinct 

 from, Otozamites Macombii ~N. from the Upper Triassic rocks 

 of Sonora, Mexico. (Report of the San Juan Expedition, p. 

 141, PI. IV, figs. 1, 2). In that species the pinnules are broader, 

 are abruptly rounded or truncated at the summit, and on the 

 lower part of the frond are quadrate ; while the corresponding 

 pinnules of the plant now described are oval. Some of the 

 upper pinnules are set obliquely on the rachis, are long-ellip- 

 tical in outline, slightly curved or sigmoidal, are obliquely 

 rounded at the base and attached by a single point, thus con- 

 forming strictly to the definition of Glossozamites Schimper, 

 and serving as a connecting link between that genus and 

 Otozamites. "Whether the rachis in our plant is furrowed as 

 in the type species of Glossozamites (G. Zittelli Schenk) is 

 not certain, but apparently it is so. Figure 10 represents one 

 of the longer pinnules detached.
