Name derivation:
Mentha a Latin name of a Greek nymph who was turned into a mint plant. Satureioides means resembling the genus Satureia (which is from the Latin 'satureia' meaning savory).
Found scattered from the Gammon, Flinders and Mount Lofty Ranges, southern Eyre Peninsula and the upper South-east in South Australia, growing on heavy, seasonally wet soils. Also found Queensland, New South Wales and Victoria.
Native. Rare in South Australia. Common in the other states.
Plant description:
Rhizomatous, often mat-forming perennial herb with ascending or prostrate branches, often rooting at lower nodes, glabrous or covered with short spreading hairs. Leaves narrowly elliptic, to 35 mm long and 7 mm wide, surfaces glabrous, apex obtuse or rounded, margin entire. Inflorescence in clusters with 3  tubular white or pink flowers in axils of distal leaves. Flowering from November to March.
Fruit type:
Small clusters of papery brown capsules in axis of leaves.
Seed type:
Dark brown to black ovoid seed to 1.2  mm long and 0.7 mm wide, with a slightly wrinkled surface.
Embryo type:
Seed collecting:
Collect individual capsules that are turning brown and contain hard seeds or break off whole stems with numerous brown capsules.
Seed cleaning:
Place the capsules in a tray and leave to dry for a week. Then rub the capsules gently with a rubber bung to dislodge the seeds from the capsules. Use a sieve to separate the unwanted material. Some seeds will be empty.  Use an aspirator to siphon off the lighter, non-viable seeds from the heavier good seeds. 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.
Seed viability:
From one collection, the seed viability was low, at 15%.
