Cp (NC, SC, VA), Mt (VA): frequently cultivated, sometimes escaped as a waif or "throw-out"; rare, introduced from s. Asia. June-November. [= RAB, C, F, G, K, S] Impatiens capensis Meerburg, Orange Jewelweed, Orange Touch-me-not, Spotted Touch-me-not. Mt, Pd, Cp (GA, NC, SC, VA): moist forests, bottomlands, cove forests, streambanks, bogs; common (rare in Coastal Plain of GA). May-November. Newfoundland west to Saskatchewan and AK, south to SC, panhandle FL, AL, and TX. Within the portion of our area where I. capensis and I. pallida overlap, the two species often occur in mixed populations. I. capensis tends to have the leaf apices and crenulations more rounded than I. pallida, but the character is overlapping and variable.

[= K] BATACEAE von Martius ex Meisner 1842 (Batis Family) A monogeneric family, low shrubs, of tropical and subtropical shores of the Americas, New Guinea, the Pacific, and Australia. References: Rogers (1982b); Bayer & Appel in Kubitzki & Bayer (2003). Batis P. Browne 1756 (Saltwort, Beachwort, Batis) A genus of 2 species, low shrubs, of tropical and subtropical shores of the Americas, New Guinea, the Pacific, and Australia. The only other member of the family and genus is B. argillicola, of New Guinea and Australia. References: Rogers (1982b); Goldblatt (1976); Bayer & Appel in Kubitzki & Bayer (2003). Batis maritima Linnaeus, Saltwort, Beachwort, Batis. Cp (GA, NC?, SC): brackish marshes; rare north of GA (but locally common). June-July; October. Se. SC south to s. FL, west to TX, and in Central and South America (apparently introduced in BERBERIDACEAE 225 HI). B. maritima is alleged (as by S) to occur as far north as NC, but the documentation is unknown; there is no twentieth century evidence to place Batis in NC. [= RAB, GW, K, S, Z] BEGONIACEAE C. Agardh 1824 (Begonia Family) Begonia Linnaeus (Begonia) * Begonia cucullata Willdenow, Begonia. Cp (GA): disturbed places; rare, native of South America. Escaped or persistent in e. GA (Jones and Coile 1988) south to FL (Wunderlin 1998). [= K] BERBERIDACEAE A.L. de Jussieu 1789 (Barberry Family) As broadly defined here, a family of about 15 genera and 650 species, herbs and shrubs, of the temperate Northern Hemisphere and Andean South America. There has been much debate and study of whether the Berberidaceae shold be recognized as a broadly defined unit, or split into a variety of segregate families (such as Podophyllaceae, Epimediaceae, Nandinaceae, Leonticaceae). Based on molecular studies, Kim & Jansen (1996, 1998) conclude that division of the Berberidaceae into segregate families is not warranted.
