Its habitat in Alabama is discussed, and related to Caret ezilis habitats in adjacent southern Mississippi. KEY Vt,'ORDS: Carez erilis, Cyperaceae, Alabama, seepage herb bogs drez exiiis Dewey (section Siellulatae) is primarily a north temperate bo- real sedge, occurring in fens and bogs from Delaware acd Maryland north along the Atlantic coast to Keu-ioundland, and inland from Ken York to Minnesota, Michigan, and northwestern Ontario (Reznicek d. Ball 1980; Bryson, el al. 1988). All of the previous records south of Delaware are disjunct occurrences on the coastal plain of North Carolina (Moore County), and six southern Mis- sissippi counties (Greene, George, Harrison, Jackson, Pearl River, and Stone) (Bryson, et al. 1980; Reznicek & Ball 1980). Our recent discovery of C. ezilis from Mobile County, Alabama is therefore not unexpected, since it is known from three adjacent Mississippi counties. Our Baldwin County collection was somewhat less predictable since the extensive alluvial plain associated with the rivers entering Mobile Bay may represent a significant phytogeographic barrier for seepage adaptid species. The collection data for our ~ l a b a m a specimens are as follows: Carez eziiis Dewey (Cyperaceae). CNITED STATES.
