Abstract
Stypopodium shameelii Nizam. et Aisha sp. nov., has been described from the coast of Pakistan. It is characterized by regular tiers of central cells both in cross as well as in longitudinal sections, surfaces of the distal and proximal portions of the frond are elevated and smooth respectively, sporangia scattered in between the hair-lines on both surfaces and restricted to the distal portion of the frond or blade. Vegetative growth occurs by simultaneous transverse and longitudinal segmentations of the apical cells. The genus Srypopodium Kütz., is also emended. The validity of S. tubruqense Nizam. & Godeh is also discussed.
