COSEWIC assessment and status report on the Anticosti Aster Symphyotrichum anticostense in Canada / Committee on the Status of Endangered Wildlife in Canada.: CW69-14/757-2017E-PDF
"Anticosti Aster is a 10 to 75 cm tall, herbaceous species that spreads by long rhizomes to form loose clonal colonies. The stiff, narrowly linear leaves are somewhat leathery in texture, often arched, and have smooth or minutely toothed margins. Flowers are in long-stalked flower heads composed of purple ray (petal-like) florets and yellow disk florets. Anticosti Aster is a Holocene (<11,700 year old) species that originated by hybridization of New York Aster and Rush Aster. Identification based solely on morphologyis not entirely reliable, particularly in New Brunswick due primarily to similarity with narrow-leaved forms of New York Aster. It is of interest as a rare regional endemic species of post-glacial origin that grows in association with many other plant species of conservation concern within regionally significant calcareous river shore communities"--Wildlife Species Description and Significance, p. iv.
