Hypericum olympicum Form olympicum (Nomenclature)
Stems erect or more rarely decumbent, sometimes branched below inflorescence. Leaves (10–)20–38 × (2–)5– 12 mm, elliptic or elliptic-oblong to lanceolate (l : b = 4–5), acute to subacute, usually with black intramarginal glands. Flowers 2.5–5.5 mm in diam. Petals nearly always golden yellow (very rarely producing lemon-yellow-petalled flowers from seedlings in cultivation).
Range of the species except southern Greece.
Hypericum olympicum var. coronense is a local variant with black-gland-dotted sepals that could perhaps result from a single mutation. I have seen the type, from near the Corona Monastery, Agrafa, Sterea Ellas; and Jordanov & Kožukharov (1970) record it from Melnik in the southern Pirin Mountains, southwestern Bulgaria. The population on Ikaría also has this character; see under forma minus.
