Two nutlets, one somewhat damaged, agree so closely with Sideritis scordioides 

 (fig. 17), a plant of the Mediterranean Region and Spain, that we have little doubt they 

 belong to this plant; but the genus Sideritis is so large that we hesitate to name them 

 with absolute confidence. A thin skin is easily rubbed off the recent Sideritis nutlets, 

 leaving a surface like that seen on our fossil. 



LYCOPUS EUROPAEUS Linn. 



PI. XVI, figs. 19, 20. 



A few nutlets of this species have been found. They are figured side by side 

 with recent specimens (figs. 21, 22), but call for no further remark. The living plant has 

 an exceedingly wide range. Reuver, Swalmen. 



HANCEA Sp. 

 PI. XVI, fig. 23. 



Nutlet obovate narrowed below, attachment rounded projecting inward ; surface 

 finely striate. 



Length 1.8 mm., breadth 1.3 mm. Brunssum. 



The only genus oiLabiatae having nutlets with the very peculiar attachment seen 

 in our fossil is Hancea, a small genus living in China. The only species in the Kew 

 Herbarium with ripe fruits is H. nudipes Hemsl. ; our fossil differs only in the nutlet 

 being obovate instead of roundedsoval (this may be due to crushing), and in being 

 somewhat more striate. 



Hancea are shrubs of 4 feet, growing in the mountains of China. Wilson records 

 them at 4000 feet, and Henry between 6000 feet and 7000 feet. 



GENUS? Sp. 1. 

 PI. XVI, fig. 24. 



Nutlet small elongate*obovate, dorsal face flattened, ventral face sharply angled ; 

 attachment elongate triangular; dorsal and ventral faces covered with fine but conspic* 

 uous longitudinal striae, which give a toothed appearance to the upper end. 



Length 1.5 mm., breadth 0.8 mm. Swalmen, Reuver. 



We are unable to suggest the generic position of this nutlet, which is quite unlike 

 any labiate we have seen. 



GENUS? Sp. 2 (= Tegelen 1910, fig. 42). 



PL XVI, figs. 25—27. 



Nutlet obovate narrowed at the base inflated, keeled on the ventral face ; surface 

 minutely tubercled. 



Length 2 mm., breadth 1 mm. Reuver, Brunssum.
