BE. HEEE ON THE FOSSIL ELOEA OE BOVEY TEACEY. 
Tongrian and Aquitanian stages. It has been found at Weissenfels in Saxony, at 
Salzhausen and Miinzenberg, at Thorens in Savoy, and at Manosque in Provence. 
Hitherto no perfect leaves or pinnules have been found at Bovey, but so many 
portions of pinnules that one can easily put together the entire pinnule, as we have 
tried to do in Plate LVI. fig. 8. The pinnule is in length 173 millims., its extreme 
breadth 21 millims. ; it gradually tapers towards the apex, and forms a long sharp point 
(Plate LVI. figs. 2-4, and magnified fig. 1). The pinnule is also narrower at the base 
than in the middle ; at least several pieces evidently belonging to the base are narrower 
than those from the middle of the pinnule (fig. 5). The pinnule is shortly petioled, 
and has often unequal sides at the base. There are many such pinnules around a finely 
striated rachis ; portions of which latter common rachis are often found (cf. Plate LV. 
figs. 5, 4 «, & 8) between the pinnules, and in several cases I have seen the lateral 
pinnules attached. 
The pinnules are of a strong, almost leathery consistence, and, examined with a lens, 
they appear to he finely punctate. Their margin is deeply toothed, the broad portions 
in the middle of the pinnule are nearly pinnatifid, the teeth on the outer margin smaller, 
and closer together. All these teeth are strongly bent towards the apex ; the long side 
forms a strongly-curved arch ; they are entire, and provided at the tip with a distinctly 
separated little tooth. The midrib is pretty strong ; the secondary nerves spring at the 
base of the leaf in slightly acute angles, and in more acute ones in the upper narrower 
part of the pinnule. They are mostly more or less curved, and on each side they send 
forking tertiary nerves, on the upper part (nearer the tip) mostly one or two less than 
on the lower one. The broad pieces of pinnules have on the lower side seven or eight 
tertiary nerves ; the number lessens nearer to the tip, as the pinnules gradually taper 
(we count there 6, 5, 4, 3, 2), and quite near the tip they are undivided (fig. I), Each 
of the tertiary nerves soon divides into two branches, which do not again divide; only 
the exterior ones remain entire. Those tertiary nerves are everywhere equally strong, 
and sometimes the fourth or fifth advances to the margin, whilst the following one is 
again forking. The lowest ones are very strongly curved, and enter the sinus always 
between two teeth. The lowest tertiary nerves do not generally join the nerve of the 
neighbouring pinnules (Plate LVII. figs. 1, 4 & 5), or only in the sinus, forming a very 
acute-angled triangle (figs. 3 & 7). In some cases they unite like Gonio^teris, already 
a httle lower (Plate LVII. fig. 2), forming several very acute-angled arches. The ter- 
tiary neiwes mostly spring from the secondary ; but sometimes a fine forking nerve 
immediately springs from the principal nerve (Plate LVII. figs. 1-5), and runs to the 
sinus of the teeth. 
A portion of a leaf very different in the nervation is figured in Plate LVII. fig. 6 
(magnified). The tertiary nerves spring at very acute angles ; they are very numerous, 
and some of them are twice forked. The teeth seem to have been narrower and longer. 
This fragment may belong to another species, but is too imperfect to pronounce any
