Temnoma palmatum

Terrestrial, bright green to pale yellowish-brown. Branches almost always arising from main stem abaxial to modified lateral leaf with fewer lobes, rarely from beside an underleaf with fewer lobes or from near unmodified underleaves. Leaves 4-lobed, obtrapezoidal in outline, 425–950 μm long, 525–1075 μm wide, transverse or succubous in insertion, patent, slightly concave adaxially; lobes long-triangular, gradually narrowing toward acute apex, 0.4–0.65 of the overall leaf length, 3–14 cells wide at base, entire or with teeth; disc 5–12 cells long, entire or with 1–4 teeth or cilia. Underleaves smaller than lateral leaves, 200–575 μm long, 250–725 μm wide, otherwise similar to lateral leaves. Leaf cells oblong to polygonal in disc, 20–72 μm long, 15–35 μm wide, more elongate in cilia, striolate with numerous small papillae, firm- to thick-walled, with 2–4 (–11) oil bodies; oil bodies spherical to irregularly ovoid, colourless, homogeneous. Bracts larger than vegetative leaves; lobes with (1–) 2–4 (–6) pairs of teeth. Perianth ovoid to obconical or short-tubular, crispate or plicate and sometimes obscurely 3-plicate toward apex, usually stipitate, with a ciliate mouth.
