Roots 2, or 2–10 in 2 groups at each node. Leaf sheath 5(–20) cm long, persisting longer than leaves. Leaves 2–4(–5) per shoot, 5–60 cm long, 1–3 mm wide; apex rounded with a notch; longitudinal veins 3. Generative branches 5–30 cm long, with 1–several spathes. Spadix linear-lanceolate; with 4–12 broadly triangular bracts, each enclosing an anther. Flowers and fruits Oct.–Mar.
EGL, GipP, Glep, OtP, VVP, WaP, WPro. Common in inlets and estuaries on mud and sand in shallow, calm waters.
There is overlap in many of the morphological features used to distinguish Z. muelleri, Z. murconata Hartog, and Z. capricorni. Further research is required to determine if these taxa represent good species or are better treated as subspecies.
Plants growing in estuarine situations usually have longer leaves with longer flowering branches than the form which occurs in lagoons and other land-locked waters.
