%X <em>Aleuritopteris argentea</em> is a small ornamental ferns. We observed the developmental features of gametophyte and sporophyte of <em>A.argentea</em> cultured in Knop's medium and humus medium using microscopical techniques, and studied the optimum pH value for the gametophyte development. The results show that:(1)the spores are yellow-brown, tetrahedral, and trilete with reticulate ornamentations. Polar view is triangle circle and the equatorial view is nearly semicircular. The germination is Vittaria-type and the gametophyte development is Ceratopteris-type. The mature gametophytes are cordate. The archegonia and antheridia are leptosporangiate-type. No hairs are formed during gametophyte development. The above features of the gametophytes in the fern <em>A.argentea</em> are stable. (2)the enhancement the pH value in 7.0-9.0 is beneficial for spore germination and gametophyte development. (3)the spore and gametophytes develop on humus medium produced seedlings after 7-8 weeks. The viability of sporophytes obtain in this medium are strong with developed roots and easy to transplant. Percentage of seedling emergency reaches to 90%. Our investigation is benefit for the artificial propagation and evolution of the resource plant <em>A.argentea</em>.
