Taxonomy and spore morphology of 12 taxa of Cheilanthoideae and Pteridoideae (Pteridaceae, Polypodiales) from Pakistan is illustrated with scanning electron microscopy images based upon the specimens collected from various localities. A total of six genera belong to 12 taxa viz. Actiniopteris radiata, Aleuritopteris albomarginata, A. ancepes, Notholaena himalaica, Oeosporangium nitidulum, O. pteridioides subsp. acrosticum, Onychium cryptogrammoides subsp. cryptogrammoides, O. vermae, Pteris cretica subsp. cretica, P. cretica subsp. laeta, P. vittata subsp. emodi, and P. vittata subsp. vittata were reported. Spore morphology of the taxa was trilete, triangular in proximal and distal view, ellipsoidal and hemicircular in equatorial view, polar proximal and distal surface with cristate, granulose, reticulate, perforate and tuberculate ornamentation.
