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. FAMILY REFERENCE: Adams (1973)=Z; Godfrey (1988)=Y; Wood & Adams (1976); Stevens in Kubitzki, Bayer, & Stevens (2007).

WEAKLEY FLORA
SCIENTIFIC NAME: Hypericum buckleyi
COMMON NAME: Granite Dome St. John's-wort
SYNONYMY: [= GW, RAB, S, W, V, X, Z; = H. buckleii - K, orthographic variant]
PHENOLOGY: Jun-Aug.
HABITAT: Thin soil in seasonal seepage around rock outcrops, particularly granitic exfoliation domes.
COMMENTS: Sw. NC south to nw. SC and ne. GA, a Southern Appalachian endemic. Wilbur (1995) showed that Curtiss spelling of the epithet, buckleii, should be maintained; however, changes in the International Code of Botanical Nomenclature have reversed this (Robson 1996).
