The up to three leaves of Moraea lewisiae subsp. lewisiae grow spaced and sessile from the lower stem. They are long, narrow and may trail or twist, becoming about 5 mm wide. The linear blades are channelled without midribs (Curtis-Scott, et al, 2020; Vlok and Schutte-Vlok, 2015; Manning, 2007; Manning and Goldblatt, 1997; iNaturalist; https://www.fernkloof.org.za).
