STAPHYLEA Sp. 3. 



Dr. Tesch has recently obtained from Tegelen another broken seed belonging 

 to Staphylea. It differs both from that just described and from the one previously 

 figured from Tegelen. 



We appear to have therefore 3 species of Staphylea in the Pliocene deposits of 

 Limburg. But all are represented only by broken seeds, and there are still several of 

 the newly discovered Chinese species the seeds of which we have been unable to 

 examine. Under these circumstances we prefer not to name them as undescribed forms. 



ACERACEAE. 



Broken fruits and seeds belonging to at least 3 species of Acer have been found 

 in the Reuverian. We have been unable to identify any of them with a living form, and 

 none of them corresponds with either of the species found at Tegelen. Only one of 

 these species of Acer is, however, represented by a fruit sufficiently well-preserved, and 

 sufficiently well charactized, to be described and named as new. 



ACER STRIATUM Sp. nov. 

 PI. XI, fig. 5. 

 Fructus parvus, rhomboideus, ad alarum commisuram incurvus ; ALA ANGUSTA, 



CUM AXI ANGULUM 45° EFFICIENS ; FRUCTUS UT ALAE STRIIS LONGITUDINALIBUS FILAMEN* 

 TOSIS IN FRUCTU RETICULATA SED IN ALIS APPROXIMATE ET PARALLELIS TECTUS. 



Fruit small, compressed, rhomboidal, incurved at the junction with the wing; 

 wing narrow, given off at an angle of 45° with the axis ; fruit and wing covered with 

 thread*like longitudinal striae, which are reticulate on the fruit but close and parallel 

 on the wing. 



Length of fruit without wing 5 mm. Swalmen, Reuver. 



This species is unlike any living maple in the Kew Herbarium. In the character 

 of its venation, and in the very flat fruit it resembles the Chinese A. carpinifolium and 

 A. pictum; but the shape of the seed is quite unlike in both these species, being elongate* 

 ovate instead of round as in our fossil. The angle at which the wing is given off is also 

 different. 



ACER cf. LOBELII Pax. 



PI. XI, fig. 6. 



This species, in the shape and venation as well as in the very flat unmodelled 

 character of its fruit, seems nearest to A. Lobelii Pax, a tree of the Caucasus of the 

 mountains of the near east, and also of China; but the fossil fruits are not in a good 

 state of preservation, and we are unable further to describe them. They were found 

 at Swalmen.
