material available for study is such that it can be sectioned and 

 subjected to critical examination under the microscope. Thus 

 far the only specimens which we have so examined are those from 

 Kreischerville, but it is hoped that the investigation may be con- 

 tinued in the future so as to include specimens from other localities. 



Protodammara speciosa n. gen. et sp. 



Plate 1, Figs. 5-13; Plate 2, Figs. 1-5 



"Dammara microlepis Heer (?)." Hollick, Ann. N. Y. Acad. Sci., vol. 

 11, p. 57, pi. 3, iigs. 9 a, b, 1898. 



Organisms consisting of kite-shaped cone scales, from 4 to 6 mm. 

 long by 4 to 6 mm. broad above, abruptly narrowed from about the 

 middle to the base, rounded, incurved, and apiculate above; resin 

 ducts five or more, extending down the lower surface of the limb; 

 seed scars three in number, crescentically arranged above the middle 

 and approximately in the broadest part of the scale, with the central 

 one higher up than the laterals. 



Plate 1, Figs. 5-13, shows the scales natural size; Phito 2. Figs. 

 1 a. b, c, 2, shows four specimens with the upjH-r sui faccs cxpox-d, 

 magnified about ten diameters. Although they may In- x'fii to 

 resemble closely those of a small female cone of Dammara they 

 are distinguished from the scales of that gemis the apical proc- 

 ess and by the fact that thev obviously bore three see.ls instead 

 of only one. It miglit indeed be inferred, fn.ni the presence of 

 three apically attached ovules, that we have here to do with cone 

 scales of one of the Secnioiiiiea', rather than with one of the Araii- 

 carineae, but the iiiTernal structure shows that they are truly 

 Araucarian. 



Plate 2, Fig. 3, represents a transverse section of tlie base of a 

 scale, magnified about 40 times. A little below the middle j.oii.t 

 may be seen a single small fibrovascular bundle. At a higher 

 plane of section this separates off a single upper bun<ll(> of imrrted 

 orientation and gives off a number of lateral bundles to th(> lou t r 

 surface of the scale. The upper bundle supplies the seeds. In 

 the higher part of the scale the inferior bundles are surrounded
