Several other similar bogs were examined in the general area but no other Schizaea were found. The bedrock underlying the Litde Salmon River site is supposedly the same type as at the Chance Harbour site (Ferguson and Fyffe 1985). At all localities where Schizaea has been discov- ered in New Brunswick, the habitat closely resem- bles sites in Newfoundland and Nova Scotia where the authors have seen this species. According to Roland and Smith (1969), Schizaea occurs in Nova Scotia in sphagnous bogs, peaty borders of lakes, sphagnous hollows and wet undrained depressions, and it is often abundant near the coast. Observations made at the New Brunswick localities for this species support Lellinger's generalization that Schizaea favours highly acid, humus-rich soil (Lellinger 1985). Although it is possible that Schizaea has recently become established in New Brunswick, it is more plausible that it had been overlooked because of its inconspicuousness. Further exploration of suitable habitat, especially along the Bay of Fundy, may reveal that this species is more generally distributed than these collections indicate. Schizaea should be looked for in the more open bogs and fens where its. Figure 2. Photograph of Schizaea pusilla from the "power line bog" near Chance Harbour. Photograph taken by J. P.
