Rhodora 50: 12, plate 1090, fig. 2. 1948.
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.

Of conservation concern.
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.
