|
Name derivation:
|
Evolvulus from the Latin 'evolvere' meaning to unroll; referring to their non-twining habit. Alsinoides means resembling a species of the genus Alsine. Villosicalyx from the Latin 'villus' meaning shaggy hair and from the Greek 'kalyx' meaning cup-shaped; referring to the species hairy sepals. |
|
Distribution:
|
Found in the northern part of South Australia, growing on sand, loam and clay in claypans, along drainage lines and dunes. Also found in Western Australia, Northern Territory, Queensland and New South Wales. |
|
Status:
|
Native. Common in South Australia. Common in the other states. |
|
Plant description:
|
Perennial herbs or subshrubs with ascending or prostrate hairy stems. Leaves entire, hairy. Inflorescence axillary with a single blue/white funnel-shaped flower. Flowering throughout the year but mainly between March and August. Evolvulus alsinoides var. villosicalyx differ from the other variety E. alsinoides var. decumbens by having the peduncles shorter than or rarely equalling the leaves (much longer than the leaves in var. decumbens), pedicels 1–4 mm long (2–7 mm long in var. decumbens) and sepals 4–5 mm long, densely hairy, hairs spreading (2–3mm long, sparsely to densely hairy, hairs appressed to spreading in var. decumbens). |
|
Fruit type:
|
Brown globular capsule with hairy sepals, splitting into 4 valves. |
|
Seed type:
|
Orange to brown sectoroid seed to 1.5 mm long and 1.2 mm wide, glabrous. |
|
Embryo type:
|
Folded. |
|
Seed collecting:
|
Collect capsules that are maturing, turning brown and contain hard seeds inside. Capsules can be opened or unopened and some seed can be collected from the ground under the plant. |
|
Seed cleaning:
|
Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently by hand or with a rubber bung 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. |
|
Seed viability:
|
From one collection, the seed viability was average, at 65%. |
|
Seed germination:
|
This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking the seed coat). |
