This seed when originally described from Tegelen (op. cit) was thought to 

 belong to Stratiotes or some allied genus. A study of the living Phellodendron shows 

 however that the fossil certainly belongs to this genus. Phellodendron in germinating 

 divides into two valves (fig. 13), and most of our fossil seeds have opened in the same 

 way (fig. 11). The testa is crustaceous and somewhat fragile; the fossils therefore are 

 usually much broken. 



PHELLODENDRON TESSELATUM Sp. nov. 

 PL X, fig. 15. 



Semina magna, semiovoidea, sculptura e foveolis regularibus quadrangulis 

 constituta ornata. 



Seed large semiovate, ventral margin nearly straight, dorsal margin rounded, 

 point not projecting beyond the ventral line; sculpture of equal longitudinal and trans* 

 verse ribs, forming regular quadrangular pits. 



Length 7 mm., breadth 4 mm. Reuver. 



Differs from all the recent species in the regular tesselated pattern of its testa; 

 and from P. elegans in its straight margin without incurved point, and the absence of 

 strong longitudinal ribs. It is the largest seed in the genus. None of the recent species 

 has so regular a surface*sculpture as is seen in either of our fossils. 



GENUS? 

 PI. X, figs. 9 a, b. 



These figures represent the endocarp of some rutaceous genus, in which the 

 endocarp dehisces and is ejected. Reuver. 



SIMARUBACEAE? 



GENUS? 



Some endocarps perhaps belonging to this family, or to Sabiaceae, are described 

 on p. 113 and figured on Plate XI, figs. 26, 27. 



MELIACEAE. 



TURRAEA Sp.? 

 PL X, figs. 16 a, b. 



Seed oblong curved, compressed towards ventral margin; hilum broad lateral 

 with somewhat winged margin, and remains of large aril(?) which partly envelopes the 

 base of the seed; testa black shining, sculpture small irregular pits. 



Length 5.5 mm., breadth 2.3 mm. Brunssum.
