文摘

Lower Cretaceous conifer Pseudofrenelopsis gansuensis were micro- and ultrastructurally studied. Statistics give distinction among epidermal cells, subsidiary and guard cells. Ten ultrastructural features have potential specific value, eleven generic and three Cheirolepidiaceae Family value. EDS analysis gives species differences between 3 ratios using N, S, K, Cl.
