The Swalmen species of Diospyros is quite different from that found at Bruns* 

 sum. Its kernel is smaller, narrower, more ovate, pointed below, and more finely 

 wrinkled. We can find no living Diospyros having these characters, and the species is 

 probably extinct; but as in this genus there is considerable variation in the seeds in a 

 single fruit, we do not care to found a new species on one specimen. Nearly all living 

 species of Diospyros have seeds with a straight ventral margin; none that we have seen 

 has the kernel so symmetrically oval. 



STYRACACEAE. 



STYRAX MUCRONATUM Sp. nov. 

 PI. XVI, figs. 4, 5, 8. 



Semina magna, elongato*ovata, mucronata, hilo parvo. 



Seed large elongatesovate mucronate; hilum small. 



Length 14 mm., breadth 7 mm. Reuver, Swalmen. 



Our seeds appear all to have germinated and are more or less broken. We take 

 fig. 4 as the type of the new species ; for it is not quite certain that fig. 5, which is 

 crushed vertically, belongs to the same plant. The type specimen has 3 raised lines, 

 marking the abortive locules, and its raphe is broad and conspicuous. The seed has split 

 open at the base and has curled back, making the specimen very difficult to photograph 

 satisfactorily. The character of the testa (fig. 8) corresponds closely with that of 

 S. japonicum (fig. 7). 



It is noticeable that our fossil is allied to the Japanese and Chinese species 

 5. japonicum (fig. 6) and S. Obassia, not to the European 5. officinalis; it is however 

 specifically distinct from either and we have been unable to match it among living 

 species. 



OLEACEAE. 



JASMIMUM UNDULATUM Ker*Gawl.? 

 PI. XVI, fig. 9. 



Fruit elongate*ovate; epicarp close smooth not wrinkled; seed large, testa covered 

 with zig*zag and wavy irregular striae. 



Length 7 mm., breadth 4 mm. Swalmen. 



This fruit is very much larger than the species next to be described, and retains 

 its outer coat. In size and shape it bears considerable resemblance to J. undulatum, a 

 species of China, Himalaya, and Burma; but so large a proportion of the jasmines in 

 the herbaria are not represented by fruiting specimens, that we cannot carry the deter* 

 mination further. We have only seen one specimen of the fossil fruit.
