Distribution of locations where Prunus pumila var. pumila has been found on the Canadian shores of the lower Great Lakes (dots) and corresponding regions (numbers). For the basis of the map and key to numbers, see Table 1. of Long Point (Figure 1 - region 5). James Black's 1854* survey included a "shrub community" extend- ing from the tip of the point 12 km to the west [see also Heffernan (1978*) and Heffernan and Nelson (1979)]. Dwarf Cherry was one of the species fre- quently noted in this zone on Black's transects. Dwarf Cherry was probably not listed in subsequent early surveys of the flora of Norfolk County because it had already become rare. Dwarf Cherry was pre- sent, but very rare on the outer portions of Long Point and particularly in the Gravelly Bay area in the late 1960s (personal observation). Heffernan and Nelson (1979) noted that no Dwarf Cherry occurred in the areas where it had been reported by Chewett (1793*) or Black (1854*), and that there were only a few, very small clumps in the Provincial Park at the base of Long Point. Dwarf Cherry was not seen on the outer portions of the point in the 1980s by Reznicek and Catling (1989), who also reported it only from the park at the base of the point. There is a specimen of Dwarf Cherry from Rondeau Park (Figure 1 - region 6) collected in 1905 (Table 1), but there are no other records from this location, nor was any reference to it at this loca- tion found in any of the early surveyor's notes. It could not be located there in 1994 during a survey of the entire east beach, although there is extensive sandy shore habitat. Dodge (1914) noted that Dwarf Cherry was "fre- quent at Point Pelee (Figure 1 - region 7) in sandy open ground and on upper ; Some later refer- ences with almost identical wording (, Mosquin 1988*) are evidently based on Dodge's report.
