(S. racemosa Greene) Goldenrod Verge d'or. After ; D'après: herbaria HABITAT: Dolomitic limestone cliffs and pavennents, rocky woods, and sand dunes. STATUS: Rare in New Brunswick and Quebec. NOTES: Very similar to var. randii which also occurs in Ontario, but only on shoreline rocks along the eastern and northern coasts of Lake Superior.

Atlas of the Rare Vascular Plants of Ontario / Atlas des plantes vasculaires rares de l'Ontario ASTERACEAE Solidago spathulata DC. ssp. randii (Porter) Cronq. var. racemosa (Greene) Cronq. (S. racemosa Greene) Goldenrod Verge d'or. After ; D'après: herbaria HABITAT: Dolomitic limestone cliffs and pavennents, rocky woods, and sand dunes. STATUS: Rare in New Brunswick and Quebec. NOTES: Very similar to var. randii which also occurs in Ontario, but only on shoreline rocks along the eastern and northern coasts of Lake Superior. The Ontario populations of var. racemosa are tetraploid (2n = 36) while those of var. randii are diploid (2n = 18). HABITAT: Falaises calcaires et lapiés dolomitiques, bois rocailleux et dunes. SITUATION: Rare au Nouveau-Brunswick et au Ouébec. REMARQUES: Ressemble fortement à la variété randll qui croît également en Ontario, mais uniquement parmi les roches couvrant les rives orientale et septentrionale du lac Supérieur. On a découvert que la var. racemosa était tétraploïde (2n = 36) en Ontario, alors que la var. rancf//est diploïde (2n = 18). REFERENCES / SOURCES Semple, , Brammall, & Chmielewski. 1981.
