 about 1.5 mm. long, the axial one often a little larger and duller than the others, ovoid to 

 broadly lanceolate, rather abruptly acute at apex ; dorsal side keeled near the apex, strongly 

 rugulose with transverse ridges, then sometimes reduced to tubercles toward the base ; ventral 

 side reticulate-rugulose ; scar of the axial nutlet triangular-ovate, the other nutlets with a 

 linear or nearly linear scar.
