Swedish Phytogeographical Society



The society hosts two meetings each year, the annual meeting, usually in March, and the autumn meeting in November. Both occasions start with a formal meeting where the members are updated on the recent activities of the society, discuss changes and upcoming publications. When the meeting is closed an invited guest speaker gives a speech followed by an informal dinner.

Upcoming planned meetings:

Due to the COVID-19 Pandemic the spring meeting planned for March 26 will be held online and the seminar is postponed to a later date. Instructions on how to participate to the online meeting will be sent to all members of the Society via mail.

Francesco Spada is Professor at the department of Environmental Biology at La Sapienza University of Rome (Italy) and since many years guest Professor at Plant Ecology, Uppsala University. He will give a talk about the phylogeography of the western Eurasian Styrax officinalis.


Styrax officinalis is an Eurasian species with highly fragmented distribution in S.E. Mediterranean regions with core range in the Aegeo-Anatolian districts, reaching SW Italy and the Near East. Populations in peninsular Italy have long been considered by local scholars a human import from classic times, due to its very restricted local range close to Rome, the overall scanty and isolated populations and an uncritical treatment of historical sources about an alleged local use of its exudate in the past. Nevertheless the floral framework of its associates in the Italian stands is rich in species belonging to the eastern geo-element of the European flora, alternatively suggesting native status of the species. Closest relative is S. redivivus in SW/N America, adding intriguing issues about intercontinental disjunctions during the evolutionary history of S. officinalis s.l. We performed population genetic analysis using genome-wide sequencing markers in order to reconstruct patterns of geographical differentiation and demographic history (time of differentiation, migration routes) of the species, on samples selected from the whole total range of S. officinalis in the Mediterranean regions, from Lebanon to Provence, Results from the genetic analyses support generalized relictuality all over the W European range of the species and of the Italian populations specifically, rather than human import.
