Introduction

A diminutive perennial with bulb-like basal tubers, restricted to brackish seashores and estuaries in BC. Known in Greater Vancouver from the head of Burrard Inlet, the Serpentine estuary, Little Campbell River estuary and Iona Island (UBC: Lomer 97-596). It does not grow in freshwater sites in The Fraser Valley. I expect that a thorough search of coastal estuaries in brackish sites, where the tidal shore is exposed compacted mud, will reveal that this species is not of conservation concern in BC. [Note that out of range dots on the distribution map represent transcription errors in specimen coordinates that are not yet updated by data providers--ed.]
