A plant up to 90 cm tall with tuberous roots that are usually between 15 mm long and
5-10 mm wide. Leaves: The leaves are flat and up to 40 cm long and 1-7 mm wide.
Flowers:The inflorescence is either racemose (succession along stem where oldest
flower is at the base) or paniculate (inflorescence with primary and secondary axis,
branched). There is one flower per node (stem joint), however there may occasionally
be two from the lower nodes. The flower stalks are up to 35 cm long and each flower
has bracts (leaf-like structures) that are between 5-15 mm long. All flower parts are
between 6-14 mm long and purple in colour. The outer segments are between 3-4 mm
wide and the inner ones between 6-10 mm wide. The margins are narrowly fringed.
The anthers (pollen sacs) are between 3-4.5 mm long and are either purple or yellow.
The filaments (stalk holding anthers) are flattened. The ovary is between 1-1.5 mm in
diameter. The flowers have a distinctive scent, which smells like chocolate. Fruit:
The fruit is a capsule that is spherical in shape and between 4-7 mm in diameter. It is
usually enclosed in the remnants of the flower parts. The seeds are black and angular
(description from Curtis & Morris 1994). Herbarium specimens have been collected
in November and December. This species was previously known as Dichopogon
Dichopogon strictus (R.Br.) Baker APNI*
Synonyms: Arthropodium strictum R.Br. APNI*
