Enrique RubioDo any of you know where the holotype of Arpinia luteola var. luteola could be found if it exists?
Does anyone have material of this species for study and sequencing?
Many thanks in advance
Enrique

Re : Arpinia luteola
Hello Enrique,

the protologue says the holotype is in Leiden, no number given. Their online catalogue lists two specimens labelled as type (same date and collector) and one later collection by someone else:
