Symphyotrichum shortii (formerly Aster shortii), commonly called Short's aster, [3] is a species of flowering plant in the family Asteraceae. It is native to North America, where it is primarily found in interior areas east of the Mississippi River. [4] Its natural habitat is in thin rocky soils of woodlands and thickets often around limestone bluffs. [5] [4] It is common throughout much of its range, although it is generally restricted to intact natural communities. [5]

Description

Symphyotrichum shortii is a perennial herbaceous plant growing up to 110 centimeters (3.5 feet). It produces heads of flowers with purple rays in late summer and fall. Unlike many related Symphyotrichum, its stem leaves are essentially entire and do not have a winged petiole. It bears a resemblance to the related Symphyotrichum oolentangiense of farther west, from which S. shortii can be distinguished by its cordate stem leaves and pubescent phyllaries. [6]

Chromosomes

S. shortii has a base number of x = 8. Diploid and tetraploid cytotypes with respective chromosome counts of 16 and 32 have been reported. [7]

Taxonomy

The species was first formally described and named Aster shortii by English botanist John Lindley in 1834. [8] A natural hybrid of S. shortii and S. cordifolium can occur, and this has been named Symphyotrichum × finkii. [7]

Distribution and habitat

Symphyotrichum shortii is native to North America, where it is primarily found in interior areas east of the Mississippi River. [4] Its natural habitat is in thin rocky soils of woodlands and thickets often around limestone bluffs. [5] [4] It is common throughout much of its range, although it is generally restricted to intact natural communities. [5]
