Drosera from the Greek 'droseros' meaning dewy, alluding to the glistening hairs of the glandular leaf laminae. Schmutzii named in honour of Father Erwin Schmutz SVD (Society of the Divine Word) of the German Catholic Centre, Collinswood South Australia who discovered this species. He is an accomplished and passionate field naturalist of flora, fauna and geology in Indonesia and South Australia.

Distribution and status

Endemic to South Australia and restricted to Kangaroo Island, growing in buff-yellow sandy clay with laterite pebbles, with underlying sandstone. Native. Uncommon in South Australia.

Plant description

Small herb with a red stem tuber enclosed by multi-layered black sheath. Leaves annual in a semi-erect rosette, green or red, narrowly spatulate to 35 mm long and 15 mm wide. Inflorescence in centre of rosette with 2-7 flowers; pedicels to 4 cm long, arching in fruit; petals cuneate, truncate to shallowly notched, to 14 mm long and 9 mm white. Flowering between June and September. Fruits are brown ovoid to globose capsule to 8 mm diameter. Seeds are gold oblong seed to 1 mm long and 0.8 mm wide, with a black matt-like surface.

Seed collection and propagation

Collect seeds between August and November. Collect mature capsules that are plump, hard, turning brown and contain black seeds. Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently by hand to dislodge the seeds. Use a sieve to separate the 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.

Fire response

Obligate re-seeder, only tiny seedlings noted emerging in fire scars and no re-sprouting observed.

Longevity: 1 years

Time to flowering: 1 year

Recovery work

In 2020-2021 this species was assessed post-fire in 1 year and 2 year old fire scars. A total of 9,200 seeds have been collected & banked for a population inside the 2020 fire scar. Germination screening testing the response to fire cues will be undertaken in 2021.This project was supported by the Garfield-Weston program.
