FOSSIL FKUITS. 



229 



Figs. Ill, 112 and 113 exhibit the most common fruit, always thus apparently flattened, with two valves 

 generally dehiscent. These valves are made up of fibrous matter, the fibers arranged perpendicular to the 



FIGS. Ill & 112.

surface of the valve. The seed is always wanting ; but the thin membranous integument once inclosing 

 the seed, generally remains. The point by which they were attached probably to a capsule is very indis- 

 tinct. These fruits are five times more numerous than any others.

FIG. 116. 



Fio. 117. 



Figs. 114, 115, 116 and 117 are two-valved, and more rounded than those just described, but they may 

 be only varieties of the same species. 



Fig. 118 is three-valved ; two of which are much the most distinct. It is also much more acuminate 

 than the preceding. I have found not more than two or three specimens.

Fio. 119. 



Fig. 119 shows a three-valved elongated fruit, with strong ridges on the valves. It tapers very much 

 towards the apex. It is indehiscent. 



Fig. 120 is more or less three-sided and short, the one side nearly flat, but the ridge on the other side 

 very prominent. Valves closed perhaps three. 



Fig. 121 is ridged and more or less flattened, resembling one or two species of walnut, but the covering 

 is fibrous, as in the. species first described.
