Plants 10-25 cm, herbaceous; rhizomes thin, short; rosettes not clumped; vegetative parts heavily white-farinose. Leaves not aromatic, indistinctly petiolate; petiole broadly winged; blade without deep reticulate veins abaxially, spatulate, 8-15 × 2 cm, thin, margins irregularly and sharply dentate to sinuate-dentate, apex obtuse to acute, surfaces glabrous. Inflorescences (6-)10-25-flowered; involucral bracts plane, ± equal. Pedicels erect, thin, 10-30 mm, length 2-5 times bracts, flexuous. Flowers heterostylous; calyx green, campanulate, 3-5 mm; corolla lavender, tube 8-10 mm, length 2 times calyx, eglandular, limb 10-16 mm diam., lobes 5-8 mm, apex emarginate. Capsules ellipsoid, length 1-2 times calyx. Seeds without flanged edges, reticulate. 2n = 18. Flowering summer. Moist seepage areas on carbonate bedrock in canyons; 800-2500 m; Ariz., Utah. Primula specuicola has relatively large corollas, relatively long pedicels, and irregularly and sharply dentate to sinuate-dentate leaves with conspicuous farina. It is a characteristic member of hanging-garden communities along the canyon walls of the Colorado River and its tributaries. Plants with a more exserted capsule were given the name P. hunnewellii; this appears to be only a minor variant that does not warrant infraspecific recognition.
Plant: perennial herb; 9-30 cm tall, upright stems Leaves: 2-23 cm long, petiolate; blade spatulate or elliptic, generally glandular-pubescent on the lower surface or sometimes glabrous but not mealy, the margins slightly dentate, the teeth gland-tipped (if the margins are entire, the glands terminate the main veins) INFLORESCENCE: a scapose umbel, with the bracts 4-10 mm long Flowers: dark violet with yellow center; calyx 4.5-9 mm long, generally densely mealy-white; corolla tube 8-10 mm long, the lobes 3-8 mm long; stamens 5, generally attached to the upper portion of the corolla tube; style generally shorter than the corolla tube; ovary superior Fruit: FRUITS valvate Misc: Moist sites under overhanging cliffs; 900-1400 m (2900-4600 ft); Mar-Jul REFERENCES: Cholewa Anita F. 1992.
