Name derivation:
Acrotriche from the Greek 'akron' meaning summit and 'thrix' meaning hair; alluding to the tuft of hairs at the tip of the corolla lobes. Patula from the Latin 'patulous' meaning spreading slightly.

Seed type:
Woody, pale-brown seed to 3mm long and 3mm wide.

Linear underdeveloped.
Seed collecting:

Seed cleaning:
Place the berries in a bucket of water and rub the flesh off with your hands. Drain the water and wash again if required to remove all the flesh. Then spread the wet seeds on some paper towel and leave to dry. 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 high, at 90%.
Seed germination:
This species is generally difficult to germinate, it has morphophysiological dormancy and complex germination requirements.
