Erigeron glabellus (Smooth Fleabane) - photos and description









Leaf mid stem in above photo

Basal leaf in above photo

General: Plants decumbent to erect, foliage sparingly hairy to pubescent.

Flowers:  Flower heads 1-3 per stem, light violet to whitish-pink ray florets, flower heads measured to 30 mm diameter. Ray florets measured 0.8 to 1.0 mm wide, and 8 mm long. Bracts linear, in two series, pubescent, bract measured at 7 mm long by 1 mm wide.

Leaves: Stem leaves 7-11, alternate, linear-lanceolate, sessile, stem leaf highlighted in photo above was 4.5 cm long by 5 mm wide. Basal leaves are oblanceolate and have long petioles; basal leaf highlighted above was 7 cm long by 7 mm wide. Leaves only have one prominent nerve.

Height: Height listed in Budd's Flora to 40 cm, I measured plants to 60 cm tall.

Habitat: Moist prairie and open woods.

Abundance: Common.

Origin: Native.

Similar species: Similar to Erigeron philadelphicus, to distinguish between the two:

- the stem leaves of E. philadelphicus clasp the stem, the stem leaves of E. glabellus do not clasp the stem (Taxonomic Reminder for Recognizing Saskatchewan Plants).

- E. philadelphicus leaves all or mostly clasping and auriculate; E. glabellus leaves all or mostly are NOT clasping and auriculate (in the taxonomic key for Erigeron in Budd's Flora).

Some authorities list Erigeron asper as a form E. glabellus.

When and where photographed: Above photos taken July 16th, moist prairie 40 km east of Regina, SK, and a moist roadside meadow, boreal forest, about 450 km north east of our home in Regina, SK.
