PROFESSOR HEER ON THE FOSSIL FLORA OF NORTH GREENLAND.

which is very common in the lignites of Bovey, but the pinnules are more deeply cut, 
and have not acuminate lobes. 
The genus is still doubtful. In my Bovey paper I have compared the Pecopteris 
lignitum with the Hemitelia Karstenictna (Mettenius, Icon. Filic. pi. xxix. fig. 2), the 
nervation of which is very similar. The Greenland species belongs to the same genus 
as P. lignitum. Count Saporta has described some species of fern of the same type as 
Hemitelites (H. longaevus and II. proximus , Prodrome d’une Flore Fossile des Travertins 
anciens de Sezanne, p. 334, pi. xxiv. figs. 9-11), and I believe that Pecopteris lignitum 
and P. Torelli belong to the same genus.

I have represented in my 6 Flora Arctica’ different parts of this species. Whimper’s 
collection contains only some fragments. Plate XLIII. fig. 16 is probably a rhizome; 
it is articulated and striated.

Besides the branches of Sequoia Couttsice there are on the large slab from Kudliset 
some thinner and more delicate-branched twigs, provided with very small imbricated 
leaves. These certainly belong to another coniferous tree, and closely resemble Wid- 
dringtonia Helvetica ; but the determination is doubtful, in the absence of cones, and from 
the leaves being so much compressed that it is difficult to determine their form. These 
twigs differ from Glyptostrobus, which they resemble, in the much smaller leaves. The 
branchlets are bent upwards, and the leaves are alternate, imbricate, acuminate, and 
almost cover the twigs (Plate XLI. fig. 10 b, c ).

I have tried to show in my ‘ Miocene Baltic Flora ’ that the Taxodium abounding 
everywhere in the Miocene formation agreed so closely with the living species, that it 
must he united to it. The new collection contains a great number of associated twigs 
from Atanekerdluk, several of which are very well preserved (Plate XLIII. fig. 4 «, c). 
Associated with these were some small pieces of amber (figs. 4, 6). Fig. 5 is the trans- 
verse section of the cone (from the Museum of Copenhagen).
