| Abstract: | Shoots of the fossil species Frenelopsis alata (K. Feistmantel) Knobloch (Cheirolopidiaceae) from the Cenomanian of Bohemia and Portugal demonstrate a type of branching not hitherto reported among conifers. It has been interpreted as a modification of conventional axillary branching on the basis of detailed observations on external morphology with the help of comparative studies on living species of the family Cupressaceae (e.g., Callitris species) and other fossils of frenelopsid affinity. The probable nature of the growth pattern of the shoot is discussed. |
