Cymbopogon giganteus Chiov.

Loosely tufted perennial, the basal sheaths soon falling away; culms robust, 1–3 m. high, erect, sometimes supported by stilt roots at the base.. Leaf-blades linear to narrowly lanceolate, 15–60 cm. long, 8–30 mm. wide, smooth, mostly dark green, firm, the base as wide as the sheath or more often cordate to subamplexicaul; ligule scarious, 0.3–1(–2) mm. long.. False panicle linear 20–70 cm. long; racemes 10–15 mm. long, the lowermost internode and pedicel connate and swollen.. Sessile spikelet narrowly elliptic, 3.5–5 mm. long; lower glume firmly membranous, narrowly winged, slightly concave with a V-shaped median groove towards the base, without oil streaks and intercarinal nerves or these obscure and confined to the tip; upper lemma bifid to the middle, the awn 10–17 mm. long (very rarely absent) with a distinct column.. Pedicelled spikelet narrowly lanceolate, 3.5–5 mm. long, with clear closely spaced nerves.

Deciduous savannah bushland and wooded grassland, where it is a dominant species over large regions of the savannah, constituting the major part of the herbaceous flora.

The seeds are put into sauces. The leaves are probably used to add a lemon flavour.

Can be grown by seedlings.
