GENUS INDEX

GENUS CODE: HYPER
GENUS SCIENTIFIC: Hypericum
GENUS AUTHORITY: L.
GENUS COMMON: St. Johnswort
GENUS SUMMARY: A genus of 370-420 species, trees, shrubs, and herbs, primarily temperate. Hypericum in our area is a large, complex, and interesting genus, with a number of unresolved questions remaining. Following Nürk et al. (2013), it seems best to circumscribe Hypericum to include Triadenum (in Key A) and Thornea (the latter not relevant to our area), but not Vismia and Harungana. The species treated in Key C have often been treated in the segregate genus Ascyrum; evidence from a variety of disciplines now suggests that they should be included in Hypericum (Adams & Robson 1961; Calie, Schilling, & Webb 1983; Robson 1996; Nürk et al. 2013). Triadenum, while almost basal in Hypericum, should also be included (Nürk et al. 2013).
GENUS IDENTIFICATION: Identification notes: “Longest leaves” should be sought at branch nodes.

FAMILY INDEX

FAMILY CODE: HYPERIC
FAMILY SCIENTIFIC: Hypericaceae
FAMILY AUTHORITY: A.L. de Jussieu 1789
FAMILY COMMON: St. John's-wort Family
FAMILY SUMMARY: A family of 7-9 genera and 480-560 species, herbs, shrubs, and trees, nearly cosmopolitan. It appears from molecular analysis that recognition of the Hypericaceae is (after all) warranted. Hypericum is in a clade with Podostemum and Bonnetia, sister to a clade including Clusiaceae s.s. (Savolainen et al. 2000), and unless the morphologically very different Podostemaceae is to be included in a broad Clusiaceae, Hypericaceae and Podostemaceae must be recognized.

HORTICULTURAL
Plant Sale Text: Roundpod St. Johnswort generally grows as a single stem with deep green, linear leaves whose edges fold inwards. In early summer the numerous bright yellow flowers appear at the top each stem. The individual flowers are born upon distinctive stalks and are about 1/3in diameter. Roundpod St. Johnswort prefers moist to wet soils, but can grow in drier settings if given a little shade extra water during periods of extreme drought. The genus Hypericum supports up to 20 species of lepidoptera.
