Allocasuarina from the Greek 'allos' meaning other or different, indicating the relationship with the genus Casuarina (first used by Rumphius (1743) in allusion to the supposed resemblance of the "foliage" of Casuarina equisetifolia to the plumage of the Cassowary, which is from the Malay 'kesuari', later being latinised as Casuarius). Pusilla from Latin meaning very small, may refer to the small habit of the plant.

Seeds are smooth semi-flat black seeds to 5 mm long, with a papery wing at one end. Seed embryo type is investing.
Seed collection and propagation
Collect seeds between January and December. Cones can be collected anytime as mature cones remain on the female plant. Collect cones that have closed valves from the lower part of the stem as these are more mature. Place cones in a paper bag and leave to dry for 2-3 weeks. This will allow the valves to dry and open, releasing the seeds. Then place the cones in a bucket and shake gently to dislodge the seeds. Use a sieve to separate seeds from 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 From one collection, the seed viability was average, at 65%. Seeds are non-dormant, viable seed should germinate readily.
