Juncus from the Latin 'jungere' meaning to tie or bind; referring to the use of the rushes for weaving and basketry. Sarophorus from the Greek 'saron' meaning broom and the suffix '-phoros' meaning to bear; referring to its dense broom-shaped inflorescence.

Found in the southern Mount Lofty Ranges in South Australia, growing in damp and swampy areas that are inundated or saturated for a considerable period. Also found in New South Wales, Victoria and Tasmania.

Plant description:
Strongly rhizomatous perennial sedge to 120 cm high with terete culms to 4 mm diameter, hard, blue-green, with an interrupted pith; stem striations 25-50. Inflorescence a rather dense broom-shaped lateral panicle to 15 cm long with straw-brown flowers in loosely clustered to solitary. Flowering between December to March.

Clusters of golden brown ellipsoid capsules with numerous seeds.
Seed type:
Tiny orange ellipsoid seed to 0.5 mm long and 0.2 mm wide, with fine reticulated surface.
Embryo type:
Broad.
Seed collecting:
Collect fruits either by picking off the mature heads, those turning brown and come-off easily or break-off the whole spikes.
Seed cleaning:
Place the heads in a tray and leave to dry for one to two weeks. Then rub the heads with a rubber bung to dislodge the seeds. Use a sieve to separate any unwanted material. Be careful, as the seeds are very small. Seeds are brown and hard. 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.
