PROFESSOR HEER ON THE FOSSIL FLORA. OF NORTH GREENLAND. 461 
Drymeia, Platanus Guillelmse, Sassafras Ferretianum, Hedera MacClurii, Viburnum 
Whymperi, Cornus hyperboreus, Rhamnus Eridani, Crataegus antiqua. 
VI. To these may be added 5 Cryptogams, of which the position in the vegetable 
kingdom is quite certain, viz. : — 
Aspidium Meyeri, Lastrsea Stiriaca, Pteris (Eningensis, Osmunda Heerii (Gaud.), 
and Equisetum arcticum. 
It must be allowed that the systematic position of a number of plants from North 
Greenland is as yet uncertain. The families to which Daphnogene Kanii , the M c Clin- 
tocldas , and Pterospermites are to be assigned are not satisfactorily determined, while 
the remains of the plants described by me as Dryandra, Ficus , Ilex , Aralia , Blius, and 
Nyssa are questionable. However, the number of species which have been positively 
identified is so large, that it enables us to give a sketch of the Miocene Flora of North 
Greenland. 
II. List of the Plants, and descriptions of the New Species.

1 . Aspidium Meyeri, Pleer, Plate XXXIX. figs. 1-3. Fronde pinnata, pinnis patentibus, 
lanceolato-linearibus, profunde pinnati-partitis vel pinnatisectis, laciniis oblongis, 
apice rotundatis, integerrimis, nervis tertiariis furcatis ; soris biseriatis, indusio 
orbiculato. Hr. FI. Tert. Plelv. i. p. 36, pi. xi. fig. 2. Hub. Ujararsusuk (figs. 1, 2). 
Kudliset (fig. 3). 
This remarkable fern seems to have been very common in Disco. The best specimens 
(Plate XXXIX. fig. 1) are from Ujararsusuk. Rachis pretty thick, leaflets numerous, 
lying in all directions. On most of the pinnules are traces of sori, sometimes very well 
preserved. Pinnules pretty close-set, of considerable length (fig. 1 c ), deeply pinnately 
lobed, the lobes contiguous at the base or remote. Pinnules of the largest leaves are 
5-g- millims. broad, and 12 long ; shorter, smaller, and somewhat bent upwards at the 
apex ; near the base they spring from the rachis almost at a right angle. Lower pin- 
nules oblong, rounded at the apex, which is not the case with the upper ones. Secon- 
dary nerves contiguous, and mostly forked (fig. 1, magnified). Sori in two lines of 3-5 
each along the principal nerve (fig. la a, magn.) halfway between the midrib and the 
margin. Fig. If (If f, magn.) shows two ranges of sori. With the lens we perceive 
in them a great many small round impressions left by the capsules. Fig. 1 a (magn. a, a) 
represents a fine portion of a leaf with the indusia, which are circular, and seem not to 
be emarginate. In fig. 2 the pinnules are united higher up at the base ; nevertheless 
this specimen from Ujararsusuk probably belongs to the same species; the pinnules 
being also obtusely rounded. 
These Greenland leaves agree with the molasse plant from Lausanne and Ruppen. 
It differs from Aspidium Fscheri, lir., in the obtuse pinnules and forked secondary nerves.
