Comments: 2014, Coll. No. 1059, 28 Aug 2014: Perennial herb, of eastern slope, to 50 cm.; Leaves alternate, to 12 cm. × 2 cm. wide; margin shallowly toothed; Bracts, 15 mm., pinnately toothed, some basal and some clearly arising from the capsule; Petals, 10+, 40 mm. × 7 mm. wide; Stamens many; Filaments broad, narrowing at distal end; Anthers basifixed; Capsule, 30 mm. × 10 mm. diameter, erect, not curved at base, thick cylindric; Calyx (in fruit), lobes 9-12 mm.; Seeds, horizontal in capsule and winged, 3.8 mm. × 2.5 mm. wide, wing width 0.5-0.8 mm.

Typically, M. nuda is described as having “1 or 2 bracts usually at base” of capsule (Harrington, 1954), or “bracts not fused to ovary wall” (Weber & Wittmann, 2012), or “bracts free from capsule” (Ackerfield, 2015). However, this collection clearly has 15 mm. pinnatifid bracts arising from the capsule. Such character would lead to M. decapetala. Regardless, the small size of those bracts, and small size of other characters support placing this in M. nuda rather than M. decapetala.
