16 NATHORST. FOSSILS PLANTS OF FRANZ JOSEF LAND. [NORW. POL. EXP. 



The specimen fig. 23 is broader than the others (4 mm.), but not more 

 so than fully permits of its belonging to the same species. A similar specimen 

 from Spitsbergen is figured in my work cited above (PI. I, fig. 14). 



ABIETITES, Coeppert. 



Abietites(?) sp. 

 PI. I. figs. 42, and (magnified) 53. 



In my opinion this leaf is complete, and not the apex of a leaf of Pinites 

 (Pityophyllum) as seems proved by its narrowing off at its base and the 

 special structure thereof. It may therefore be compared to leaves of Isuga; 

 as however there may be a question also of Sequoia and other genera it can- 

 not be determined with certainty. Nor do the other conifer remains give 

 any clue, as among them seeds are found which may be said to point both 

 to Abies and Sequoia. 



PINITES, Endllcher. 



There cannot be the slightest doubt that the genus Pinus to the extent 

 hat Linne has allowed it - - is represented in the fossil flora from Franz, 

 Josef Land. As, however, the various remains are usually found separately, 

 there is no possibility of deciding, in each case, whether there may not also 

 occur some closely allied but now extinct genus. It is therefore wiser to use 

 the denomination Pinites for these remains, which in no way precludes that 

 in many cases, they should in reality belong to Pinus itself. In accordance 

 with the nomenclature 1 already in use we will call the leaves Pityophyllum ; 

 the twigs Pityodadus; the cones Pityostrobus ; the seeds Pityospermum; 

 the male flowers Pityanthus. It is plainly more correct to name these organs 

 separately than to connect them with one another, which will always prove 

 more or less arbitrary and uncertain. These names are of course provisional, 

 and will be withdrawn, so soon as the connection of the different organs with 

 one another be proved. 



Pityanthus sp. 



PI. II. figs. 7, and (magnified) 7 a. 



It appears to me fairly certain that this object is a Pinus-\\ke male 

 flower, though the details of the structure of the anthers cannot be disting- 

 uished. Their edges appear however to have been fimbriated.
