The nearest living plant appears to be the monotypic Orixa, a shrub or small tree of 

 China and Japan. Orixa japonica (fig. 6.) has four carpels, which are larger, more rounded, 

 and differently veined from ours. We can see no evidence that the Brunssum plant 

 ever had more than two carpels; but the resemblances are so much closer to Orixa than 

 to any other genus, that we feel bound to modify the genus slightly, so as to take 

 in this species. 



RUTA Sp. 

 PL X, fig. 7. 



Carpel small, ovate cuspidate rounded dorsally ; longitudinally striate or sparsely 

 granulate; dehiscing widely above on the ventral face, scarcely adhering to the adjoining 

 carpels. 



Length 4.5 mm., breadth 2.5 mm. Brunssum. 



The single carpel, which is all we have seen, evidently belongs to Rata, and we 

 have figured Ruta Corsica (fig. 8) for comparison. Our fossil carpel, however, only 

 adheres to the adjoining carpels for about 1 /s of its length, whilst that of Ruta Corsica 

 adheres for a much greater distance, and the photograph shows where it has been torn 

 away. We doubt if our fossil is specifically determinable. 



RUTA Sp. 



A single much crushed granulate seed also belongs to the genus Ruta; but it is 

 not sufficiently well preserved for specific determination or photography. It does not 

 belong to R. graveolens. 



Length 3 mm. Reuver. 



The large size of this seed makes it improbable that it can belong to the capsule 

 already described, and the two specimens do not come from the same locality. It seems 

 therefore that two species of Ruta have been found among these fossils. 



PHELLODENDRON ELEGANS (Reid). 

 PL X, figs. 10-12. 



Seed obovate pointed below, point curved towards the ventral margin, ventral 

 margin inflated above incurved below, dorsal margin and apex rounded, sides regularly 

 tumid; sculpture about 12 sharp somewhat irregular longitudinal ridges crossed by 

 short transverse ribs, giving a strongly decussate or rectangularly pitted surface; chalaza 

 large and conspicuous. 



Length 6.0 mm., breadth 3.7 mm. Tegelen, Reuver, Swalmen. 



Differs from P. japonicum (figs. 13, 14) and other living species in its larger size, 

 more rounded outline, curved base, and the boldness and regularity of its sculpture. The 

 seed from Reuver (fig. 10) is slightly more elongate than those from Tegelen (figs. 11,12); 

 but in other respects they agree.
