ALVIN, K. L. 1977. The conifers Frenelopsis and Manica in the Cretaceous of Portugal. Palaeontology, 20, 2, 387–404.
K. L. Alvin Frenelopsis Schenk has been used to accommodate various species of fossil conifers with segmented shoots and small scale-like leaves at the nodes. As a contribution to the revision of conifers of this type, some of which probably have an affinity with Hirmeriella Horhammer, the species from the Cretaceous of Portugal are here redescribed. Four species are now recognized: three (one tentatively) are retained in Frenelopsis, while the fourth, with spirally instead of cyclically arranged leaves, is placed in Monica Watson.
