paleobotany, plant morphology

Tidskrift, vol. 60, no. 3. |One of the twentieth century's most important paleobotanists, Rudolf
Florin spent his entire professional career affiliated with Stockholm
University. There he pursued research on the epidermal structures of living
and fossil plants, particularly conifers and taxads. His unsurpassed knowledge
of morphology in these (and some other) groups in turn laid the groundwork
for systematics investigations involving both phylogenetic and biogeographic
reconstructions. His studies ranged to considerations of floras all over
the world, and temporally from the mid-Paleozoic on. One of his best known
publications was his "The Distribution of Conifer and Taxad Genera
in Time and Space," in which he posed various effects of the developed,
and then disappearing, Tethys Sea. Much of Florin's evolutionary
work was based on his adoption of Walter Zimmerman's telome theory.
He was also a celebrated and honored conservationist, if mainly within
his homeland only.|
