1068 DE. HEEE ON THE E088IL ELOEA OF BOVET TEACEY. 
The leaf is hard, leathery, and tapers towards the petiole, narrow-lanceolate, the sides 
almost parallel ; the apex is not preserved in the leaves of Bovey. The median neiwe is 
pretty strong ; the whole leaf is covered with a fine polygonal reticulation (fig. 10 a 
portion of a leaf magnified), which reaches from the median nerve to the margin and 
has almost everywhere meshes of the same size. Only at some few places in this reticu- 
lation there appear delicate secondary nerves, which rise at a very acute angle. It very 
well agrees in the form and nervation with pi. 22. fig. 9 of Ettingshausen’s work. 
This species is nearly related to Andromeda protogcea, Ung., and is perhaps a variety 
of it; the reticulation is, however, much more delicate, and can only be seen with the 
lens. The leaf of Eucalyptus oceanica, Ung., is similarly shaped, but the nervation is 
difierent.

Bovey, in the 26th bed. 
A small longitudinal, oval and entire leafiet with a short petiole. The median nerve 
is thin, and several delicate curved secondary nerves proceed from it. 
This leafiet is longer and more tapered at the base than those of the ‘ Flora Tertiaria 
Helvetice,’ but it certainly agrees with the leaf represented by Ungee in the ‘ Flora of 
Sotzka,’ pi. 26. fig. 6, and may therefore be referred to this species.

Several pieces of leaves from the 17th bed of Bovey. 
The more delicate nervation is almost obliterated in the fragments of the leaves frem 
Bovey, but these agree well with our species as to their forms and the direction of the 
secondary nerves ; nevertheless this determination cannot be considered to be quite cer- 
tain. Very similar is a leaf from the lignite of the Rhine, which is represented by 
O. Webee as Lahatia salicites (Palaeontogr. iv. p. 154, pi. 28. fig. 1) ; but the leaves 
of Bovey, like those of Lode, taper into a more elongated apex, and the arches of the 
secondary nerves approach nearer the margin.
