Primula laurentiana Fern.

Bird's-Eye Primrose

• State Rank: S2
• Global Rank: G5
• State Status: Special Concern

Habitat: Ledges, cliffs, and meadows chiefly calcareous or eastern coastal [Rocky summits and outcrops (non-forested, upland)]. [Rocky coastal (non-forested, upland)].

Range: Labrador south to fb88 northwest to Ontario.

Aids to Identification: Primroses are low-growing perennial herbs. They have flowers that are borne singly to several on a leafless stalk called a scape. Bird's-eye primrose has flowers with 5 petals with a deep notch. Where the petals meet, they form an obvious yellow eye. The color of Bird's-eye primrose varies from lavender to purplish-blue. The basal leaves and scape are covered with whitish fuzz, known as farinose. It is similar to P. mistassinica, which is also rare in fb88. However, Bird's-eye primrose is primarily coastal (P. mistassinica grows predominantly along the St. John River in Northern fb88). The notch on the petals of P. laurentiana is much deeper than that of P. mistassinica and the sepals of P. laurentiana are longer (6-9 mm compared to 3-6 mm). The bracts of P. laurentiana beneath the umbel are saccate at their base.

Ecological characteristics: Predominantly found along coastal rocks and ledges. Rarely inland.

Phenology: Flowering late spring and early summer.

Family: Primulaceae

Synonyms: Primula farinosa L. var. macropoda Fern.; Primula mistassinica var. macropoda (Fern.) Boivin.

Known Distribution in fb88:This rare plant has been documented from a total of 7 towns in the following counties: Piscataquis, Washington.

Reason(s) for rarity: At southern edge of range. Calcareous habitat in fb88 is naturally scarce.

Conservation considerations: None noted.
