Name derivation:
Cryptandra from the Greek 'kryptos' meaning hidden and 'andros' meaning a man; referrring to the hidden anthers in the hood-shaped petals. Tomentosa from the Latin 'tomentum' meaning wool, hair; referring to the tomentose branches and floral tubes.
Distribution:
Found in the southern part of South Australia, mainly in the Mount Lofty Rangdes, Murryland and the South-east, growing in in heaths and woodlands. Also found in Victoria.
Status:
Native. Common in South Australia. Common in Victoria.
Plant description:
Small straggling shrub to 30 cm high, with slender tomentose branches and slightly spiny branchlets. Leaves usually terete with closely revolute margins, to 6 mm long and less than 1 mm wide, sometimes 1-2 mm wide when the undersurface is somewhat exposed. Flowers scented, sessile in loose few-flowered heads or short spikes at the ends of the branchlets, sepals as long as the floral tube, densely tomentose with minute hairs, floral tube more or less glabrous, white. Flowering between June and October.
Fruit type:
Brown obovoid capsule to 3 mm long, with an almost flat top, and free for about one-third of its length.
Seed type:
Brown ovoid seed to 1.5 mm long and 1 mm wide, with an aril at one end.
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect fruit heads that are darkening and have a fluffy appearance. Rub the flower parts in your palm to see if there is any seed, which should be yellow-brown and hard.
Seed cleaning:
Place the heads in a tray and leave to dry for a week. Then rub the heads with your hands or 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 low, at 30%.
Seed germination:
This species has morphophysiological dormancy that need to be overcome for the seed to germinate.
