Hypericum hypericoides (Linnaeus) Crantz. St. Andrew's Cross. Phen: May-Aug. Hab: Dry forests and woodlands. Dist: 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.

Origin/Endemic status: Native

Taxonomy Comments: Very variable and probably warranting division into at least varieties. 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.
