1. Braya fernaldii Abbe, Rhodora. 50: 12, plate 1090, fig. 2. 1948.

Braya purpurascens (R. Brown) Bunge ex Ledebour var. fernaldii (Abbe) B. Boivin

Plants scapose; moderately to densely pubescent, trichomes 2-forked and simple. Stems simple or few to several from base, erect, 0.2-0.7(-10) dm. Basal leaves: blade narrowly spatulate to oblanceolate, (0.5-)1-3(-4) cm × 1-3 mm, base (membranous), broadly expanded near point of attachment, margins entire, (sparsely ciliate proximally), apex obtuse. Cauline leaves: 0 or 1 (or a leaflike bract subtending proximalmost pedicel). Fruiting pedicels erect or ascending, 1-2.6 mm. Flowers: sepals 2-2.6 × 1-1.5 mm; petals white or rose-purple, 2.4-3.8(-4) × (0.8-)1-1.3(-2) mm, (claw and blade often gradually and not well-differentiated, apex rounded); filaments 1.7-2 mm; anthers oblong, 0.3-0.4 mm. Fruits lanceoloid-subulate, not torulose, (straight), (0.3-) 0.4-0.7 cm × (0.7-)1-1.5(-1.7) mm; valves densely to moderately pubescent, trichomes 2-forked and simple; septum margin broadly expanded basally (forming sacklike pouch around proximalmost seed in each locule); ovules 10-16 per ovary; style (0.5-)0.6-1(-1.2) mm; stigma 2-lobed or entire. Seeds uniseriate, oblong, (0.9-)1-1.3 × (0.4-)0.5-0.6(-0.7) mm. 2n = 56.

Flowering Jun-Jul. Limestone barrens; of conservation concern; 0-60 m; Nfld. and Labr. (Nfld.).

Braya fernaldii and B. longii are closely related northwestern Newfoundland endemics that differ from the remaining species of Braya by their lanceoloid-subulate fruits and septum margins that broadly expand basally to produce a sacklike pouch around bases of proximalmost seeds in each locule.
