Among the nine newly instituted miospore species, Ancyrospora? implicata was erected to embrace trilete pseudosaccate miospores possessing an exoexine equatorially sculptured with discrete conus- and spine-like projections having mostly truncate and bifurcate distal termini. The attribution of this species to Ancyrospora was regarded as...
