Name derivation:
Zygophyllum from the Greek 'zygon' meaning pair and 'phyllon' meaning leaf; referring to the pair of leaflets making up each leaf. Tesquorum means of waste ground or desert; referring to its habitat in the centre of Australia.
Found in the far north-western part in South Australia, growing in disturbed areas on calcareous soils. Also found in Western Australia and the Northern Territory.
Native. Rare in South Australia. Common in the other states.
Plant description:
Erect to spreading herb to 30 cm high with glabrous ridged stems. Leaves opposite, succulent, green, oblong to ellpotic, Y-shaped, to 18 mm long and 8 mm wide, glabrous. Inflorescence solitary at each node with white flowers. Flowering between July and September.
Fruit type:
Ovoid capsule to 11 mm long, strongly 5-angled (but not winged), on a long stalk.
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect semi-dried and dried capsules by running your hands through the stems of the plant. Mature fruits will come off easily and will have a hard and dark seed inside each segment.
Seed cleaning:
Place the capsules in a tray and leave to dry for 1 to 2 weeks, depending on the greenness of the fruit. Then rub the dried capsules to dislodge the seeds. Use a sieve to remove 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.
