The revised generic diagnosis, specific description and synonymy of the Late Cretaceous Rosannia manika from Alberta, Canada: Its phytogeography and affinity with family Lactoridaceae
چکیده انگلیسی
The genus Rosannia was erroneously diagnosed as a monad in Srivastava (1968a). It is re-diagnosed and its type species Rosannia manika is redescribed. The lost holotype is replaced by the surviving isotype as a lectotype here. Epitypes are designated and illustrated in this study to explain the morphology of R. manika in detail. Rosannia is an obligate ana-ulcerate tetrad with calymmate exine and granulose supratectal ornamentation. Its worldwide occurrence ranges from the Turonian to the Miocene. Lactoripollenites Zavada and Benson is a junior synonym of Rosannia. Pollen of extant Lactoris fernandeziana Phil. has a close morphological affinity with Rosannia. Lactoris fernandeziana of the monotypic family Lactoridaceae is endemic to Robinson Crusoe Island (formerly Masatierra Island) in the Juan Fernández Archipelago, Chile.
