Name derivation:
Triglochin from the Greek 'treis' meaning three and 'glochis' meaning a point; referring to its three-sided carpels. The species is un-named and the phrase name was used in the The Flora of Australia, volume 39 .
Distribution:
Found in the north-eastern part of South Australia, growing on margins of pools & salt lakes, winter-wet areas and temporarily damp soil in a variety of habitats. Also found in Western Australia and the Northern Territory.
Status:
Native. 
Plant description:
Small tufted, upright to decumbent annual herb to 10 cm high. Leaves flat and thread-like, usually longer than the inflorescence. Inflorescence with fruiting part at the top. Flowering between June and September.
Fruit type:
Purple or straw-coloured narrowly pyramid fruit on a very short stalk with six seed segments (carpels), 3 fertile alternating with 3 undeveloped sterile ones. 
Seed type:
Purple or straw-coloured narrow wedge-shaped seed with 2 lateral spurs at the base.
Embryo type:
Linear.
Seed collecting:
Collect mature fruits either by breaking off individual spikes or by removing plants that are drying off with fruits that are straw-colour and seed segments coming apart easily.
Seed cleaning:
Place the fruit spikes in a tray and leave to dry for 1 to 2 weeks. Then rub the dried fruit spikes with a rubber bung to dislodge the seeds. Use a sieve to separate any unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
