*C. inornata* was in the Ottawa (Ontario) region in the fifties at least as
early as '53. It was not in the Montreal area in the late fifties and early
sixties, or in the northern Adirondacks or northern Vermont at that time.
It was polymorphic in the Ottawa region with dark and light forms and with
upland meadow and sedge bog ecotypes in late spring and early summer.
Munroe assured me he had found it in the Gatineau hills as late as August.
Shortly after this a new race/subspecies/species was described from the
Thousand Islands. The polymorphism was very noticeable and quite unlike the
monomorphic populations of Hudsonian muskeg around James Bay, which looked
almost Skandinavian in facies.
What change in land-use practices, or what genetic introduction
prompted this rapid spread of an Hudsonian-Canadian Zone species, southward
into the Transition Zone. Could this be in response to the effects of "acid
rain" and its effects on grassland habitat? We never found it in the early
sixties in Massachusetts, Connecticut or northern New Jersey. A canvassing
of collections might produce data for the construction of a range-change map.
