Many other populations are small, consisting, in some cases, of individual plants
. Atlas of the rare vascular plants of Ontario. Rare plants; Botany. Specimens / Spécimens CAN, DAG, HAM, LKHD, MICH, OAC, PFM, QK, TRTE, UWO, WLU O Pre 1925 (D 1925-1949 9 1950-1964 ⢠POSM964. HABITAT: Dry to moist tinickets and woods. STATUS: Rare in Canada. Endangered in North Caro- lina and North Dakota; threatened in South Carolina; rare in Alabama, Georgia, and South Dakota. NOTES: Several of the northern populations, which are probably clones, are under heavy rabbit prédation and rarely flower or fruit. Many other populations are small, consisting, in some cases, of individual plants (J. Ambrose pers. comm.). This species was reported from Sydney Bay on the Bruce Peninsula (Thomson 1970), but no specimen was collected. It was found along a roadside and may have been planted (G. Thomson pers. comm.). HABITAT: Forêts et fourrés secs à humides. SITUATION: Rare au Canada. Menacée d'extinction en Caroline du Nord et au Dakota du Nord; menacée en Caroline du Sud; rare en Alabama, en Géorgie et au Dakota du Sud. REMARQUES: Plusieurs des populations dans le nord de sa distribution, vraisemblablement des clones, sont ravagées par les lapins, et produisent rarement des fleurs ou des fruits. Beaucoup d'autres populations sont réduites, se limitant dans certains cas à des individus isolés (J. Ambrose comm. pers.). On signale la présence de cette espèce dans la baie Sydney, péninsule Bruce (Thomson 1970), mais on n'a pas rapporté de spéci- men. La plante se trouvait sur le bas-côté d'une route, où elle avait peut-être été plantée (G. Thomson comm. pers.). REFERENCES / SOURCES Fox, , & Soper. 1953.
