Fig. 1. Recent Pandanus, of S. America, twenty feet 

 high, with its fruit attached. (Mirbel.) 



Fig. 2. Fossil fruit of Podocarya, from the Inferior Oolite, 

 near Charmouth, Dorset. Great part of the surface 

 is covered with a stellated Epicarpium ; the points 

 of many seeds project in those parts (^) where the 

 Epicarpium is wanting. (Original.) 



Fig. 3. Reverse of Fig. 2. shewing the seeds placed in 

 single cells (b) around the circumference of the fruit. 

 These seeds stand on a congeries of foot-stalks (d) 

 composed of long fibres, which terminate in the re- 

 ceptacle, (r) The surface of the receptacle is studded 

 over with small disks, in which these foot-stalks 

 originate. (Original.) 



Fig. 4. Base of the same fruit, shewing the transverse

Fig. 5. A single seed of Podocarya converted to carbo- 

 nate of lime. Nat. size. . (Original.) 



Fig. 6. The same magnified. (Original.)
