Hypericum maculatum subsp. maculatum (Nomenclature)
Stems always with complete subsidiary lines. Leaves with densely reticulate tertiary venation; pale glands usually absent but sometimes few to numerous. Inflorescence branches narrowly ascending, making an angle of c. 30° with stem. Flowers 15-25 mm in diam. Sepals broadly ovate to broadly elliptic or elliptic-oblong, entire or more rarely slightly eroded-denticulate; laminar glands pale and black, punctiform. Petals entire, without or rarely with 1-3 black marginal glands; laminar glands all or mostly black, punctiform or proximally shortly striiform. Styles equalling ovary.
2n = 16 (Noack, 1939; Robson, 1956, 1957; Schwarz, 1965; Reynaud, 1975; Dimetrieva, 1986; Parfenov & Dimetrieva, 1987), n = 8 (Nielsen, 1924; Winge, 1925; Robson, 1956, 1957, 1984; Laane, 1969).
Subalpine and alpine regions of the Pyrenees, Alps and Balkans; hilly regions further north (Massif Central, Vosges, Ardennes, Scotland); 0-2050 m (lowland in the north).
Distribution of the species except for lowland NW. Europe (but with enclaves in the Ardennes and western and central Scotland) and valleys of the Alps east to Styria.
Fries rejected the name H. dubium for his plant (H. tetragonum Fries).
Fröhlich (1911: 547) saw Nolte's type of H. commutatum Nolte and identified it as H. maculatum subsp. typicum var. punctatum (Schinz) A. Fröhl.
Fröhlich (p. 546) names forms glabrum and subnervosum (based on nervation) as well as and rotundifolium and angustifolium (based on leaf shape) for both vars. genuinum and punctatum; but giving the same epithet to infraspecific taxa within the same species is inadmissable (I.C.B.N. Art. 24, note 2). The epithet f. luteum, however, was given to subsp. typicum as a whole and would therefore appear to be valid.
