【 摘 要 】
The members of Pteridaceae are known varied in vegetative and generative structures. However, information about the generative characteristics is not well known, especially spore characters. The objective of this study is to learn the diversity of Pteridaceae reproductive structures in the Mount Ciremai National Park. Exploration was conducted in September in 2 locations: Mandirancang and Cigugur Sub-districts in 3 different ecosystems, i.e. homogeneous, heterogeneous and restoration areas. Observation of reproduction structure is done by observing the characteristic of sori position; shape and location of indusia; shape, color and spore ornamentation. Exploration in Mount Ciremai National Park found 11 species of Pteridaceae which are A. capillus-veneris, A. hispidulum, A. lunulatum, C. tenuifolia, Cheilanthes sp., C. fraxinea, P. calomelanos, P. biaurita, P. ensiformis, P. longipinnula, P. venusta. All observed spores had a trilete shape with a triradiate aperture. Among genera differ in the characteristics of the existence, shape and location of indusia and the surface and color of spores. A. capillus-veneris and P.biaurita are cosmopolitan species. Spores of each species may have different reproduction properties when they grow in different ecosystems. Thus, ecosystem differences affect the reproduction type of each ferns.
