These nutlets are somewhat crushed, but seem to agree with an unknown species 

 from Tegelen (op. cit 1910, fig. 42). We are still unable to suggest their generic position. 



GENUS? Sp. 3. 



PL XVI, fig. 28. 



Nutlet minute obovate ventrally keeled ; attachment terminal nearly circular. 

 Length 0.8 mm., breadth 0.5 mm. Swalmen. 



A minute nutlet, in shape and size somewhat resembling Mentha. 



GENUS? Sp. 4. 

 PL XVI, fig. 29. 



Nutlet roundly obovate, produced at the base (attachment obscure) ; rounded 

 dorsally; slightly keeled ventrally; surface closely covered with a fine little*prominent 

 granulation. 



Length 2.0 mm., breadth 1.4 mm. Reuver. 



A single specimen, evidently different from any of the others. 



GENERA? Spp. 5, 6, 7. 



PL XVI, figs. 30-32. 



Three other nutlets from Reuver are shown; but the specimens are too badly 

 preserved for description. 



SOLANACEAE. 



SOLANUMSp.? 

 PL XVII, fig. 1. 



Seed orbicular compressed laterally ; covered with concentrically arranged large 

 pits with thin crenulate margins. 



Length 1.8 mm., breadth 1.8 mm. Reuver. 



This seed, of which we have seen one good specimen and a fragment of another, 

 appears to belong to some Solatium not in our collection. We figure with it S. nigrum 

 (fig. 2), to show the resemblance. 



GENUS? 



PL XIX, fig. 17. 



Seed small orbicular compressed ; covered with minute quadrate or hexagonal 

 cells with thick crenulate walls. 



Length 1.8 mm. Swalmen.
