Primulaceae : Dodecatheon pulchellum

Dodecatheon pulchellum is a perennial herb growing from white, fibrous roots and having erect flowering stems (scapes) that reach up to 50 cm in height. The simple leaves arise from a woody caudex, forming a basal rosette. The oblanceolate to spatulate leaf blades are gradually tapered into a petiole, 4-25 cm long including the petiole, 1-6 cm wide, with entire margins. The inflorescence is a few to many flowered umbel, subtended by a few bracts < 1.5 cm long, with pedicels 1-5 cm long at flowering. The calyx tube is 2-4 mm long with pointed lobes 2-6 mm long. the yellow and red corolla tube has magenta to lavender, reflexed lobes that are 9-20 mm long. the yellow stamens are inserted opposite the corolla lobes, fully protruding and surrounding the style. The fruit is a many-seeded cylindric to ovoid capsule, 7-17 mm long and 4-7 mm wide. Shootingstars bloom in May and June in moist prairie meadows and open woodlands in western South Dakota. Synonym: Primula pauciflora

Abstract

Dodecatheon pulchellum is a perennial herb growing from white, fibrous roots and having erect flowering stems (scapes) that reach up to 50 cm in height. The simple leaves arise from a woody caudex, forming a basal rosette. The oblanceolate to spatulate leaf blades are gradually tapered into a petiole, 4-25 cm long including the petiole, 1-6 cm wide, with entire margins. The inflorescence is a few to many flowered umbel, subtended by a few bracts < 1.5 cm long, with pedicels 1-5 cm long at flowering. The calyx tube is 2-4 mm long with pointed lobes 2-6 mm long. the yellow and red corolla tube has magenta to lavender, reflexed lobes that are 9-20 mm long. the yellow stamens are inserted opposite the corolla lobes, fully protruding and surrounding the style. The fruit is a many-seeded cylindric to ovoid capsule, 7-17 mm long and 4-7 mm wide. Shootingstars bloom in May and June in moist prairie meadows and open woodlands in western South Dakota. Synonym: Primula pauciflora
