Seed embryo type is spathulate.

Seed collection and propagation

Collect seeds between September and December. Collect mature seed heads that are dried and turning brown by picking off the heads and placing them in a paper bag. Be careful as the heads are spiny. Leave the heads in the paper bag to dry for at least a week. No further cleaning required if only the heads are collected. If other material were collected, use a sieve to separate the unwanted material. Whole heads can be stored with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. Seeds are non-dormant, viable seed should germinate readily. 1. Germination 100% on 1% w/v agar, 8/16 dark/light, 10oC. 2. Germination 100% on 1% w/v agar 8/16 dark/light, 15oC. 3. Germination 100% on 1% w/v 8/16 dark/light, 20oC. See
