PRUNUS Sp. 8. 

 PI. IX, figs. 35 a, b. 



The very curious globose endocarp shown in figs. 35 a, b is distorted in such a way 

 as to make description very difficult. It apparently belongs to the section Cetasus. 



Endocarp tumid or irregularly globose, blunt, not keeled; surface undulating or 

 nearly smooth striate near base. 



Length 6.0 mm., breadth 6.0 mm. Reuver. 



As we have only a single specimen we can say nothing more as to this species. 



PRUNUS TENUIPUTAMENTA Sp. nov. 

 PI. IX, figs. 36. 



Endocarpium magnum, tenuissimum, ovatum, acumine lateraliter deflexo 

 instructum, superficie laevi. 



A single gaping endocarp, which has probably germinated, represents this section 

 of the genus. 



Endocarp very thin, ovate, pointed, point turned to one side, surface smooth. 

 Length 10.5 mm., breadth 6.0 mm. Reuver. 



We can find nothing at all like this; it is allied to P. Laurocerasus. 



LEGUMINOSAE. 



WISTARIA? 



PI. XVIII, fig. 8. 



The seeds of Leguminosae are seldom found, unless they have been either pyri* 

 tised or phosphatised, as is the case with those of the London Clay. The pods also are 

 usually too soft for the method of washing adopted for the Reuverian material, and 

 most of them would be destroyed in the process. It thus happens that, though Legu= 

 minosae were probably as abundant in the Pliocene as in any other Tertiary deposit, we 

 have nothing but two indeterminable carbonized cotyledons from Swalmen, possibly 

 representing Wistaria. No doubt if anyone could devote a large amount of time to 

 splitting*up the stilbmoist lignite layers, other remains of Leguminosae would be found. 

 But till now those who have done the collecting have been fully occupied with the work of 

 boiling down, and sorting large masses of boiled material. This method is evidently 

 yielding excellent results, far more valuable than the methods formerly employed; 

 though it is obvious that we shall not obtain a thorough knowledge of the proportions 

 of the families until both methods have been used — and then we shall still have to 

 remember that certain families have no hard seeds or fruits, no deciduous leaves, and are 

 altogether succulent, so that unless we find their impressions in calcareous tufa we shall 

 miss them altogether.
