Only fragmentary leaves have been found atBovey (in the 17th bed), but they cannot 
be mistaken, since they have the characteristic nervation of this species. In one piece 
(which in fig. 12 a lies upon the slab with the apex pointing downwards) part of the 
margin is still complete, and shows the sharply indented teeth which Dr. Jiakeaefolia 
commonly has. In the same leaf the nervation is pretty well preserved. The secondary 
nerves are very delicate, and project but very little beyond the other reticulation. To 
the naked eye, or when but slightly magnified, the leaf appears dotted, owing to the 
distinctly projecting small arches which form the reticulation.

In the 17th bed of Bovey. 
It is ver}’ like the preceding species ; but the margin is generally entire, and the nerva- 
tion is more delicate, being less prominent. 
The leaf of Bovey which has been represented in fig. 10 is coriaceous, lanceolate, 
and tapering gradually towards the tip, where it ends in a point ; it is entire ; the 
median nerve is rather strong, but the secondary nerves are very delicate ; they reach to 
near the margin, where they form arches. The more delicate reticulation, which is 
formed by very small and densely crowded areoles, can be made out by the aid of a lens, 
but it is much less distinct than in the foregoing species. 
The leaf agrees well with that which has been represented in plate 99. fig. 7 of my 
‘ Flora Tertiaria.’ 
24. Detaxdeoides BAXKSiAiroLiA. (Plate LXVIII. fig. 7.) 
Dr. foliis petiolatis, fiimis, linearibus vel lanceolato-linearibus, undique argute serratis, 
basi apiceque acuminatis, nervis secundariis approximatis, subrectis, simplicibus, 
parallelis.

Bovey, in the 26th bed. 
Only the portion of a leaf represented in Plate LXVIII. fig. 7 has been found at 
Bovey. It cannot be determined with certainty, as the characters which the above 
diagnosis (copied from my ‘ Flora’) contains are not recognizable in them. 
It was certainly a hard leathery leaf with a very delicate nervation. The secondary 
nerves are but slightly indicated and run towards the teeth, which are very sharply cut. 
The fragment probably represents part of the leaf near the base, like plate 100. fig. 10
