The following description of the flora of Bovey is given, with slight
alteration, in the words of Dr. Heer, in his memoir on that district.
The woods that covered the slopes consisted mainly of a huge pine-tree
(sequoia), whose figure resembled in all probability its
highly-admired cousin, the giant Wellingtonia of California. The leafy
trees of most frequent occurrence were the cinnamon and an evergreen
oak like those now seen in Mexico. The evergreen figs, the custard
apples, and allies of the Cape jasmine, were rarer. The trees were
festooned with vines, beside which the prickly rotang palm twined its
snake-like form. In the shade of the forest throve numerous ferns, one
species of which formed trees of imposing grandeur, and there were
masses of under-wood belonging to various species of Nyssa, like the
tupelos and sour-gums of North America. This is a true picture, based
on actual facts, of the vegetation of England in the Miocene age.
But all the other wonders of the Miocene flora are thrown into the
shade by the discoveries of plants of this age which have recently
been made in Greenland, a region now bound up in what we poetically
call eternal ice, but which in the Miocene was a fair and verdant
land, rejoicing in a mild climate and rich vegetation. The beds
containing these specimens occur in various places in North Greenland;
and the principal locality, Atane-Kerdluk, is in lat. 70 N. and at an
elevation of more then a thousand feet above the sea. The plants occur
abundantly in sandstone and clay beds, and the manner in which
delicate leaves and fruits are preserved shows that they have not been
far water-borne, a conclusion which is confirmed by the occurrence of
beds of lignite of considerable thickness, and which are evidently
peaty accumulations containing trunks of trees. The collections made
have enabled Heer to catalogue 137 species, all of them of forms
proper to temperate, or even warm regions, and mostly American in
character. As many as forty-six of the species already referred to as
occurring at Bovey Tracey and Oeningen occur also in the Greenland
beds. Among the plants are many species of pines, some of them of
large size; and the beeches, oaks, planes, poplars, maples, walnuts,
limes, magnolias, and vines are apparently as well represented as in
the warm temperate zone of America at the present day. This wonderful
flora was not a merely local phenomenon, for similar plants are found
in Spitzbergen in lat. 78° 56'. It is to be further observed, that
while the general characters of these ancient Arctic plants imply a
large amount of summer heat and light, the evergreens equally imply a
mild winter. Further, though animal remains are not found with these
plants, it is probable that so rich a supply of vegetable food was not
unutilised, and that we shall some time find that there was an Arctic
fauna corresponding to the Arctic flora. How such a climate could
exist in Greenland and Spitzbergen is still a mystery. It has,
