Specimens / Spécimens CAN, DAO, LKHD, HAM, MICH, MT, OAC, PFM, QK, RPP, SLU, SSMF, TRT, TRTE, UWO, WAT, WLU O Pre 1925 <D 1925-1949 » 1950-1964 • Post 1964. HABITAT: Moist woods and stream banks. STATUS: Rare in Canada and New Jersey. NOTES: Populations of this species in Ontario are maintained only by vegetative reproduction; no repro- duction by seed was observed by J. Ambrose between 1979-1983. Although not shown by herbarium records, many populations have been eliminated from the Niagara region (J. Ambrose pers. comm.)

HABITAT: Forêts humides et rives des cours d'eau. SITUATION: Rare au Canada et au New Jersey. REMARQUES: Les populations de cette espèce que l'on trouve en Ontario se reproduisent par multiplication végétative; entre 1979 et 1983, J. Ambrose n'a observé aucun cas de reproduction par graines. De nombreuses populations ont été éliminées de la région de Niagara, un fait qui n'est pas démontré par les spécimens d'her- bier (J. Ambrose comm. pers.). REFERENCES / SOURCES Bowden, , & B.
