Surface layer of coenenchyme with rooted leaves, up to 0.40 mm long, with mostly one big, flat, thin leaf; sometimes one or two extra smaller leaves are present (Figs. 24 d, 25). Additionally a few leaf spindles are present, up to 0.50 mm long (Fig. 24 e).

Inner layer of coenenchyme with capstans, derivatives of capstans and spindles, the latter up to 0.30 mm long and often branched (Fig. 24 f–g).
