First report for Crassula helmsii in the Poitou-Charentes region, France
Crassula helmsii (Crassulaceae, EPPO A2 List) was previously only recorded in France in the Ain, Basse Normandie and Lorraine departments. It has now been reported for the first time in Chapelle-Bâton, in the Deux-Sèvres Department, Poitou-Charentes region in France.
The Conservatoire Botanique National Sud-Atlantique has released an alert datasheet describing the species, in order to collect further distribution data from botanists.
