Geissorhiza erosa buds and furled old flowers are shaped similarly, all as erect, spaced cylinders on sessile calyces. There are colour differences between tepals. The buds are smooth, the “have beens” wrinkled, the transition item in picture tricky.
Old and young calyx bases are green here, the sepal lobes papery, pointed and dry, veering away from the corolla bases mainly in their tips. The wiry green stem parts between the flowers curve slightly, while here retaining the straight axis in the inflorescence (Bond and Goldblatt, 1984; iNaturalist; https://hortflora.rbg.vic.gov.au; https://www.pacificbulbsociety.org).
