Hypericum hypericoides (Linnaeus) Crantz. Section: Myriandra. Common name: St. Andrew's Cross. Phenology: May-Aug. Habitat: Dry forests and woodlands. Distribution: NJ, w. VA, c. KY, se. MO, and c. OK, south to s. FL and e. TX; West Indies; Mexico south to n. Central America; West Indies (Dominican Republic).

Origin/Endemic status: Native

Taxonomy Comments: Very variable and probably warranting division into at least varieties, even after the removal of H. stragulum). Coastal Plain (especially sandhill) plants are smaller- and narrower-leaved, and bluer in foliage color. The name Ascyrum linifolium Spach probably applies to the Coastal Plain entity. The Mexican-to Central-American populations seem unlikely to be conspecific. Ssp. prostratum N. Robson, of the Dominican Republic, also seems unlikely to be only subspecifically distinct from North American H. hypericoides.
