Para grass (Urochloa mutica)
Perennial grass that can form extensive
floating mats over wetlands. Stolons
(runners) to 4 m and growth to 2 m high.
Leaves to 2 cm wide, leaf sheath with dense
thick hairs. Seed head terminal with 5–20
spikelets, each 2–8 cm long.
Distinguished by leafy spreading habit,
branching at right angles to stem, and hairy

leaf sheafs and nodes.
Flowering: Most of year depending on
location
Reproduction: Spreads by seeds and
vegetatively by widely creeping stolons and
fragments. Also spread by use as a pasture
species.
Control: Physical removal, chemical control
Cumbungi (Typha orientalis, T. domingensis)
Erect native perennial herbs with flat or
slightly rounded leaves (sometimes spongy)
to 3 cm wide and growing to 3 m tall. Flower
head a dense spike above a larger spike of
female flowers.
T. domingensis (Narrow-leaf Cumbungi) is
generally shorter than T. orientalis (Broad
-leaf Cumbungi) and has a smaller, narrower
seed spike. T. domingensis is also more salt
tolerant than T. orientalis.
Typha is able to grow in water depths to
1.5 m and often forms dense stands that out
compete and reduce species diversity within

Flowering: Mostly summer
Reproduction: Seed and vegetatively from
branching rhizomes (runners)
Control: Mechanical removal, slashing,
chemical control
Effective control of small Typha infestations
can be achieved by cutting the plants 15 cm
below the water surface in autumn.
