Biebersteinia orphanidis Boiss. (Geraniaceae) is the only European rep
resentative of a chiefly Asiatic genus comprising 5 species. It was lo
ng presumed extinct in its locus classicus on Mt. Killini (N Peloponni
sos, Greece) but was recently discovered on a neighbouring mountain, S
aitas. Flowering and fruiting material was collected and some of the a
erial parts used for a preliminary analysis of essential oils. It was
found that the quantity of aliphatic hydrocarbons was rather high (25.
74%) and also that oxygenated sesquiterpenes were absent.
