Description
“Repent or erect, usually branched, short-lived perennials, or rarely annual. Floral parts in 4-7’s; hypanthium not prolonged beyond the ovary. Capsules longitudinally or poricidally multiseriate, rarely uniseriate. Most of the erect species produce basal offshoots, which have ovate to obovate leaves, in the late summer and fall. Bracteoles occur in pairs on the pedicel or stipe or on the base of the hypanthium.”[2]
"Stems erect, strict or branched, densely pubescent, to 1m tall; roots fusiform. Leaves alternate, elliptic to lanceolate, pubescent, to 10 cm long and 2.5 cm wide; sessile. Sepals 4, reflexed, ovate, pubescent, 6.5-9 mm long, 3-4 mm wide; petals 4, 7-15 mm long, 5-12 mm wide; styles 1.5-3 mm long, stylopodium prominent. Capsules cubical, 4-angled, usually narrowly winged, appressed pubescent, 6-10 mm long, 4-5.7 mm broad; bracteoles linear, 2-4 mm long; pedicels to 15 mm long.”[2]
