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.” [1]

Capsules cubical, 4-angled, usually narrowly winged, appressed pubescent to glabrous, 5-7 mm long, 3.5-5 mm broad; bracteoles linear, 2-4 mm long; pedicels to 15 mm long." [1]
