This paper contains an enumeration with short remarks of the 
plants found in brickearth near Tegelen (Holland). This brickearth 
belongs to the socalled argile de Tegelen and is considered by 
Dubois, who made the first researches on it, as an equivalent of 
the Cromer Forest-Bed. Dubois determined 11 plants by seeds and 
fruits: Prunus spec., Trapa (natans L?), Cornus mas L., Vitis cf. 
vinifeva L., Staphylea pinnata L., Juglans tephrodes Ung., Pterocarya 
fraxinifolia Spach., Magnolia cf. Kobus DC., Nuphar luteum L., 
Stratiotes Websteri Pot., Abies pectinata DC. Dr. Gothan of Berlin 
determined 5 woods: Glyptostvobus cf. heterophyllus Endl., Sequoia cf. 
sempevvirens Endl.?, Pinus, Picea or Larix and Tilia. 
C. and E. Reid consider the floras of Tegelen and of Forest- 
Bed as nearly allied but not as identical. The flora of Tegelen 
marks a stage further back, both in evolution and in climate. The 
following considerations led to this opinion. 
Most of the plants, which have been found, belong to the recent 
flora of this part of Europe. However the occurrence of a few 
Central and South-European plants certainly points to a climate 
somewhat warmer than that of Tegelen at the present day, but 
not necessarily warmer than certain other parts of the existing 
Rhine basin. As there are still many undetermined seeds of Tege¬ 
len, the authors suggest that there may be among these more or 
less extinct or exotic forms. The exotic species found at Tegelen 
and which do not occur in the Cromer Forest-Bed point to a cli¬ 
mate somewhat warmer than can be accounted for by the slight diffe- 
rence of latitude between the two localities, only 1°. Tegelen pro- 
bably had a climate such as is found 4° or 5° further south at the 
present day. This higher temperature and the larger number of 
exotic species make it possible to conclude that the Tegelen-flora 
has to be placed earlier in time than the Cromer Forest-Bed. It is 
possible that it may correspond with the Red Crag, or even with 
the Scaldesian. The autors conclude this part of the paper by the 
remark that thejr put forward this Suggestion tentatively. 
As this paper is the first, which deals with a larger list of fossil 
plants of this part of the Netherlands 1 ), I think it will be 
i) The papers of Dr. Dubois on this subject are of a more geological character. 
As they never were mentioned in the Bot. Centralblatt I will give the titles here:
