Hypericum ×inodorum

Hypericum ×inodorum Miller (syn. H. elatum Aiton) has been regarded as naturalised in Victoria on the basis of records from Warracknabeal (in 1954) and Kyneton (Willis 1973). Only the former record is substantiated by a specimen at MEL, but without any indication of its growing conditions. Hypericum ×inodorum differs from H. grandifolium chiefly in the smaller flowers (petals to 15 mm long) and in the indehiscent or incompletely dehiscent fruit. It is a partially fertile hybrid between H. androsaemum and H. hircinum, occurring in nature where the parent species grow together (south-western Europe) and in horticulture, and is occasionally cultivated.
