A Trachyandra ciliata leaf is long and narrow, soft and spongy, usually trailing. It is keeled below and channelled above or sometimes flat. Numerous longitudinal lines are visible on the strap-like blade in picture.
Hairiness can be discerned in the photo along the margins, fitting the ciliata specific name. The leaves are usually hairy all over (Privett and Lutzeyer, 2010; Manning, 2007; Manning and Goldblatt, 1996; iNaturalist).
