UMBELLIFERAE. 



Fruits of about eight species of Umbelliferae have been found ; but few of them 

 are sufficiently perfect for absolute determination. The fossil fruits of many genera in 

 this family tend to lose their ribs by decay or tearing off, and the vittae become more 

 prominent through the shrinkage of the rest of the fruit. This adds considerably to the 

 difficulty of determination. 



HYDROCOTYLEAE? GENUS? 

 PI. XV, fig. 1. 



We have only seen a singly specimen of the fruit shown in fig. 1. It seems to 

 belong to the section Hydrocotyleae, but we cannot identify the genus. 



Length 2.4 mm., breadth 1.4 mm. Reuver. 



PETROSELINUM Sp. 



PI. XV, fig. 4. 



A small fruit belongs apparently to this genus ; but we cannot further identify it. 

 Length 1.6 mm., breadth 0.7 mm. Reuver. 



CICUTA VIROSA Linn. 

 PI. XV, figs. 2, 3. 



A few fruits have been found at Swalmen; they are not very well preserved and 

 call for no remark. 



SESELINAE Sp. 1. 

 PL XV, figs. 5-9. 



Fruit narrow oblong, somewhat compressed dorsally, commisure flat; ribs 5, 

 strong, the 2 lateral somewhat broader than the other 3; vittae single between the ribs. 

 Length 2.0 mm., breadth 1.1 mm. Reuver, Swalmen. 



This fruit belongs to the section Seselinae and seems to be near to Seseli. 



SESELINAE Sp. 2. 



PI. XV, figs. 10, 11, 



Fruit small ovate; ribs narrow; vittae single between the ribs. 



Length 1.5 mm., breadth 0.8 mm. Swalmen. 



These fruits are not well preserved, and it is difficult to say whether they were
