Yes Satellitehead is correct, we use this term always, means the mother country or the country we/they originated.
Also, please to tell your friend, when he brings the cuttings to you, maybe he could separate them into bunches and marked which variety, sometimes you will get a huge bag and its all mixed up. Maybe if he give you 4or 5 or whatever cuttings from each individual, he can have them separated ahead of time for the sake of variety! It could cause identification problems when you are trying to root them. Tula would be wonderful to help you with Greek names, that would be much help.
