fruit a pod with single seed; radicle on inner face (superior?). The shrivelled remains 

 of the corolla are seen within the calyx. 



Length 6.7 mm., breadth 4.8 mm. Swalmen. 



This fruit appears to belong to the Anacardiaceae, and probably to the section 

 Rhoideae; it may be near Cotinus. In the ripe fruits belonging to several genera oiAnacan 

 diaceae (Pavishia, Swintonia, Loxostylis, etc.) the adherent calyx is much increased in size, 

 often forming wings. One of the large wings was accidentally broken off the fossil. 



PI. X, figs. 23-26. 



From Reuver and Swalmen we have obtained specimens of drupes apparently 

 belonging to the Anacardiaceae. 



Fruit drupaceous; drupe ovate pointed (fig. 26); exocarp thick striate; endocarp 

 crustaceous thick dehiscent (or splitting into 2 valves in germination, fig. 23), obovate 

 rounded, base projecting black, contrasting with the rest of the brown endocarp; hilum 

 basi*lateral?; style lateral; testa fused with the endocarp, finely striate obliquely. 



Length of fruit (with mesocarp shrunk) 6 mm., breadth 4.5 mm ; endocarp, 

 length 5.2 mm., breadth 3.5 mm. Reuver, Swalmen. 



We are unable to make certain as to the character of the seed in this fruit. The 

 large black area at the base of the endocarp is striking ; but the course followed by the 

 vessels from this point is not clear. There is however a large lateral aperture at about 

 2/3 distance from the base. 



It is probable that these drupaceous fruits belong to the same species as the fruit 

 with acrescent calyx shown in fig. 22 ; but until we obtain for dissection a second sped* 

 men in which the calyx is preserved we cannot make certain. 



AQUIFOLIACEAE. 



ILEX AQUIFOLIUM Linn. 

 PI. XI, fig. 2. 

 A single endocarp found at Reuver evidently belongs to this species, and needs 

 no further description. We have figured it side by side with a recent specimen (fig. 1). 



STAPHYLEACEAE. 



STAPHYLEA Sp. 2. 

 PI. XI, fig. 4. 

 Seed small for the genus, strongly facetted on one side (more than one seed 

 developed) narrowed toward the base ; testa finely granulate. 



Length 6 mm., breadth 5 mm. Brunssum. 



We cannot match this seed, which is unlike any recent form in the Kew Her* 

 barium. It is quite different from the large seed found at Tegelen (op cit. 1910, figs. 

 11, 12, 13), and from the recent European 5. pinnata (fig. 3).
