3. Sequoia Sternhergi, Gp. * ; has a wide distribution in the Miocene formation, from 
Senegaglia to Iceland. 
4. Sequoia Gouttsiae^ Hr. ; Bovey. 
5. Sequoia Hardtii, Gp. ; Haering and Armissan. 
6. Sequoia Langsdorji, Br. ; spread over the whole Miocene formation, in Italy, 
Germany, Switzerland, France, Isle of Mull, Greenland, Bear-lake Biver, Vancouver 
Island, from the Unga at the shore of Aleski, Russia near Orenburg. 
7. Sequoia sempervirens. Lamb. ; California. 
The genus Sequoia probably begins in the cretaceous formation; for Geinitzia {Cycor 
dopsis, Deb.) is so nearly related to Sequoia, that, according to Dr. Debey, it can scarcely 
be separated from this genus, and may be considered as the predecessor of it. This 
genus most abounded in the Miocene time ; it was spread over the whole Continent as 
far as we know. In the present creation we have but two remains of this type, both 
found only in California. These two living species represent the two extremes of all 
the known forms. Of the fossil species, S. Langsdorji especially approaches to S. semper- 
virms, and S. EhrlicM and S. Sternbergi to S. gigantea. S. Couttsice is the intermediate 
species between these two principal types. 
I now proceed to describe the Bovey specimens. 
The annual twigs (Plates LX. figs. 9-20 ; LIX. and LX. figs. 7 & 8, magnified) are 
very slender, often of considerable length (figs. 14-16), without producing lateral twigs. 
The leaves cover the twigs like scales, which are mostly very close together (Plate LX. 
fig. 10); on the long twigs they are more distant. At the base of the young shoots they 
are always closer and shorter (fig. 7), a little more outwards they are more distant. The 
leaves are alternate, though sometimes two are nearly opposite, but never exactly so. 
All the leaves are decurrent at the base. The very short scale-like leaves are somewhat 
falcately curved (cf. Plate LX. fig. 13, magnified), and still more so are the leaves which 
are more distant from one another (Plate LX. figs. 14, 15 & 17). These leaves are 
♦ I have already tried to show, in my ‘ Elora Tertiaria Helvetise,’ iii. p. 317, note, that Araucarites Stern~ 
hergi, Gp., belonged to Seguoia. MAssAiiOXGA has given, in his ‘ Specimen Ehotographicum,’ pi. 21, a 
photograph of his Araucarites venetus of Chiavon. He said that the leaves and twigs were not diiferent 
from those of Araucarites Sternhergi ; he took it for a diiferent species, because he thought, with Ungee 
and Ettingshaesen, that the cone presented under the name of Araucarites Goepgerti, St. (Sternberg, 
Pflanzen der Vorwelt, pi. 89. fig. 4; Goeppert, Eossile Coniferen, pi. 44. fig. 2), was to be referred to A. 
Sternhergi. But we have shown, in the ‘ Elora Tertiaria,’ that there are no suflicient reasons for it ; and 
the circumstance that cones are found, in Chiavon, on a twig which is not to be distinguished from A. Stern- 
hergi, and also immediately beside similar twigs in Iceland (quite different from A. Ooepperti), confirms 
this opinion. The cone of Chiavon is much compressed, and lies in a lateral position, while the cones of 
Iceland represent the transverse section (as do the pieces represented by Steenbeeg, ‘ Elora der Vorwelt,’ ii. 
pi. 57. figs. 1-3, as Steinhauera suhglohosa, Presl, which, according to my opinion, belong to this species). 
The scales of the cones are small and in great numbers, and very difierent from Araucaria, while the cone 
figiired by Massaeonga has a great resemblance to that of Seguoia gigcmtea. The seeds represented as 
Steinhauera quite agree with Seguoia,
