(P.vulgare auct.; P.vulgare subsp. serrulatum
/Arcangeli)
A Mediterranean/south Atlantic species reaching its northern
limit on Lismore, v.c. 98. For the most part requiring limestone
or similar high-calcium bearing rock substrate (e.g. mortared
walls); usually on the warmer south-facing aspect when in its
colder locations. Many records under the name P.vulgare var.
serratum Willd. have been shown to be this taxon or a hybrid of
it . (See R.H.Roberts & D.M.Synnott , Watsonia, 9: 34-41; 1972;
A.Rutherford & A.McG.Stirling, Watsonia, 9: 357-361; 1973).
