These achenes, which are fairly common, show no trace of arrangement in the 

 tubercles. Two of the Reuver specimens are shorter and broader, and are perhaps ter* 

 minal achenes. The achenes somewhat resemble, but are much larger and more elongate 

 than those of R. humilis found at Tegelen. The resemblance to R. lateriflorus (fig. 30), 

 is so close that we can only refer our fossils to that species, though the prominent beak 

 has decayed. R. lateriflorus is a plant of southern Europe and the Levant. To R. pendun* 

 culatus Lange, of Spain, a species closely allied to R. lateriflorus, the resemblance is less 

 marked. 



RANUNCULUS Sp. 

 PI. VII, fig. 34. 



A single achene representing a fourth species of the genus has been discovered, 

 but we can find no living species at all closely resembling it. Achenes of Ranunculus vary 

 considerably in shape according to their position on the receptacle, we therefore will not 

 describe this as new in the absence of more specimens. It is quite unlike the terminal 

 achenes of R. lateriflorus, which has a globose head of fruit. 



Achene elongate*obovate, style continuing ventral margin ; sides compressed but 

 tumid and strongly margined, covered with flattened tubercles and coarsely punctate. 



Length 2.2 mm., breadth 1.25 mm. Reuver. 



The tubercles in this achene are so depressed as only to show with very 

 oblique light. 



THALICTRUM BAUHINI Crantz. 

 PI. VII, figs. 35, 36. 



Achene small fusiform, 8=ribbed, subcompressed laterally somewhat inflated 

 below on the dorsal side; attachment basal. 



Length 2.6 mm., breadth 1.25 mm. Brunssum. 



The close resemblance of this achene to that of T. Bauhini Crantz (fig. 36) will be 

 seen by the figures. The principal difference is in the attachment, which in the one is 

 basal, in the other lateral ; this difference however may be due merely to the position of 

 these particular achenes on the receptacle. Only two specimens of this fossil have been 

 seen. T. Bauhini is a species of Central Europe and Asia Minor; it has been found also 

 in the Teglian. 



THALICTRUM SIMPLEX var. GALIOIDES Nest. 

 PI. VII, figs. 37, 38. 



Achene small symmetrically ovate, sharply pointed at either end, ribs prominent 

 sharp. 



Length 1.7 mm., breadth 1.0 mm. Brunssum. 



Corresponds closely with the recent fruit (fig. 38). This variety of T. simplex 

 grows in Tyrol.
