DE. HEEE ON THE FOSSIL FLOEA OF BOVET TEACET. 
acuminate, and the point is curved outwards (Plate LX. fig. 14 5, somewhat magnified). 
Amongst the great number of twigs 1 have seen, there was only one with much longer 
linear leaves (Plate LX. fig. 12, magnified fig. 12 a a) than they commonly appear 
in Sequoia Hardtii. Twigs with such long leaves therefore must be very rare. The 
small portion of a twig which is represented in fig. 9 (magnified) forms the intermediate 
form of this leaf. The leaves are always rigid, and provided at the back with an elevated 
edge, which runs to the apex of the leaf. The biennial twigs (Plate LX. figs. 1 & 2) 
are much thicker and also quite covered with leaves, which are scale-like, applied to the 
stem ; they are broader than the leaves of the annual twigs, and closer together at the 
base of the twigs. They show at different places the scars on which the alternate shoots 
have been fastened. 1 only saw one branch with whorled twigs (Plate LIX. fig. 13). 
The branches of three years (Plate LIX. figs. 9 & 11) are 5 to 6 millims in breadth. 
We see on them numerous cicatrices of branches, which indicate the insertion of the 
twigs. The leaves are nearly of the same size as those of the biennial ones ; they are, 
however, not so close together ; they are scaly, adhering to the twigs, and the epidermis 
is provided with many longitudinal wrinkles. These twigs are thicker at the base 
(Plate LIX. fig. 11). As there are many twigs found thus thicker at the base, they 
appear to have separated themselves very easily from the stem at the place of insertion. 
The leaves disappear on still thicker and therefore older twigs, and only small scars 
remain on the bark. Beside these branches of difierent ages, there are trunks which 
probably belonged to this tree. 
The cones are solitary or in pairs (Plate LIX. fig. 14, restored fig. 15), on rather 
slender twigs quite covered with scaly leaves. They are globose (Plate LIX. fig. 16, 
restored fig. 17 ; fig. 14), or shortly oval (fig. 19), from 15 to 24 millims. in length, and 
from 15 to 17 millims. in breadth. The scales are peltate, the footstalk is short, and 
seems to be central (Plate LX. figs. 29, 30 & 33) ; the upper side is polygonal, but this 
form is not constant ; in the middle is a very short mucro, from which originate several 
wrinkles that radiate to the margin ; the surface is therefore pretty roughly wrinkled. 
Cones in which the scales are closed are rare (Plate LIX. figs. 14, 16 & 18). They 
must have been enveloped by the clay when still fresh. They are often spread open and 
the scales separated from one another, and the spaces filled with clay (Plate LX. figs. 27 
& 28) ; or we have but solitary scales or portions of cones (Plate LX. figs. 29-35). 
There are several seeds beneath every scale (Plate LX. fig. 25); they are also very 
often scattered between the twigs. The seed is usually 5 millims. long and 3^ millims. 
broad, and fiat ; it is somewhat emarginate at the point of insertion, obtusely rounded 
and a little tapered towards the tip. The nucleus is somewhat curved and pretty flat. 
It is surrounded by a flat wing (Plate LX. figs. 37-41 ; fig. 41 5, magnified). 
In the lignite of Bovey both small and very large pieces of resin are found, which 
were probably secreted by the Sequoia Couttsice. 
The lignite of Bovey contains very large stems, the zones of which are mostly distinct 
and crowded ; in several stems I could count a hundred of them. One can easily split
