NO. 3.] DESCRIPTION OF SPECIES. 13 



stance; pointing therefore to rather thick leaves. A specimen, sent to me 

 after the plates were printed, is figured in fig. 2 annexed. 



Probably the specimens figs. 13, plate 38, of Newton's and Teall's 

 afore- mentioned work should be referred to this same species. 



Both in form and venation these specimens, as far 

 as can be judged from the material at hand, show no 

 small resemblance to Ginkgo pluripatita Schimper sp. 

 from the Weald of Germany 1 . More complete specimens 



are however necessary, in order to decide the relation-

ship between the two. 



Male flower of Ginkgo. 

 PL I. figs. 33 and (magnified) 49. 



This specimen is evidently a male flower of some plant belonging to 

 the Ginkgo family, probably of the genus Ginkgo itself. The anthers are 

 visible on either side of the axis, but their number or nature cannot be 

 definitely ascertained. Such male flowers of the Ginkgo family may be 

 named Ginkganthus. 



CZEKANOWSKIA, Heer. 



Csekanotvskia cf. rigida Heer. 

 PL I. figs. 35 and 54 (magnified). 



That Czekanowskia rigida, Heer (Flora foss. arctica, vol. 4) is repre- 

 sented in the collection from Franz Josef Land seems fairly indisputable from 

 the specimen fig. 35, which plainly shows the dichotomous branching of the 

 narrow leaves. The midrib is also shown very clearly. 



Besides this specimen, there are many others which seem to point to the 

 occurrence of the same species. First of all, let me mention fig. 37, a speci- 

 men which shows several leaves proceeding from a short shoot. Unfortunately 

 they are in a bad state of preservation, so that one might question whether it 

 could not be a Phoenicopsis. There is certainly also some likeness to 

 Pinites, but, for that, the leaves seem to have been of too weak a consistency. 



The specimen represented by fig. 36 may also be deemed fascicular 

 leaves of Ceekanotvskia, as also specimen fig. 38, while the specimen fig.
