In the photos you mostly see female plants but in photo 4 some males plants are obvious. A larger cluster of male plants is shown at https://www.anbg.gov.au/bryophyte/photos-captions/gigaspermum-repens-185.html and female plants with mature capsules at https://www.anbg.gov.au/bryophyte/photos-captions/gigaspermum-repens-77.html. Ferdinand von Mueller once mistook specimens of this moss for a flowering plant and described the new flowering species Trianthema humillima.
