Aneimites fertilis with seeds, Wardia fertilis n. sp. 



Page 323. 



Fig. 1. Fragment of frond, showing small, narrow form of pinnules. 

 Fig. 2. Example with proportionately broad, though small pinnules. 

 Fig. 3. Portion of pinna, probably from fertile part of the frond. 

 Fig. 3a. Detail showing characters of the small pinnule and the obscurely 

 lineate and elongately punctate rachis, enlarged to twice the nat- 

 ural size. 

 Fig. 4. Fertile apical portions of pinna?, with seeds above and reduced pin- 

 nules below. 

 Fig. 5. Similar fragment with forking, thin pedicels, dilated at the apices. 

 Fig. 5a. One of the pedicels showing a seed and one of the foliate expan- 

 sions, possibly representing an early stage in the development of 

 the polleniferous organs, enlarged to twice the natural size. 

 Fig. 6. Seed still attached to the pedicel. 



Fig. 6a. The same enlarged to twice the natural size to show the collapse of 

 the apex, and the presence of the basal scales or possibly undevel- 

 oped ovules. 

 Fig. 7. Detached mature seeds, one of which is so preserved as to show the 



outline of the nutlet, and a broken edge of the outer envelope. 

 Fig. "a. One of the seeds showing (exaggerated) the boundary of the nut- 

 let, and the minute dimples at the angles of the wing, enlarged to 

 twice the natural size. 

 Fig. 8. Pedicels with young and immature seeds. 



Fig. 9. Similar example showing undeveloped and perhaps abortive fruits. 

 Fig. 10. Seeds obliquely compressed so as to foreshorten the nutlet and re- 

 veal the continuity of the wing. 

 Fig. 100. The same, enlarged to twice the natural size to show the apex of 

 the seed, which, in the diagonally flattened specimen, appears to be 

 papillate. 

 Fig. 11. Fragment of pinna in which the apices are developed as young seeds. 

 Fig. 11a. The same, enlarged to twice the natural size to show the charac- 

 ters of the young fruits as well as of the pinnules. 

 Ftg. 12. Apical fragments with delicate dichotomous, spiral, lineate append- 

 ages, thickened at the tips, possibly representing the microspore- 

 bearing organs of the plant. 

 Fig. 12a. Portion of the same enlarged to twice the natural size to show 



some of the spiral appendages which are dense at the apices. 

 Fig. 13. Apex of a pedicel showing scars, probably those of the attachment 

 of the spiral appendages shown in Figure 12. See similar devel- 

 opment at the left of the latter figure. 



The portion at the left in Figure 13 is shown enlarged to twice 

 the natural size, and is cited as " a " in the text, p. 328. 

 Fig. 14. Pedicel, from which the seeds have fallen, showing obscure scars of 

 detachment.
