Utricularia from the Latin 'utriculus' meaning a small bottle or bladder; referring to a small insect trapping sac attached to the underground leaves. Lateriflora from the Latin 'latus' meaning side and 'florus' meaning flower; referring to the species having lateral flowers. Due to the short pedicels the flowers appear to be fastened directly to the peduncle axis.

Inflorescence erect, solitary or sometimes with 2 or more reddish stalk, with up to 5 pale lilac to mauve or violet with white or yellow spot at base of lower lip flowers. Flowering between October to January. Fruits are reddish brown globular capsule to 3 mm diameter, splitting into two. Seeds are tiny, brown and ovoid to 0.3 mm long and 0.2 mm wide.
Seed collection and propagation
Collect seeds between November and February. Collect mature capsules, those turning reddish brown colour, fat and containing brown seeds. Can collect individual capsules or break off the whole stem. Place the capsules in a tray and leave to dry for two weeks. Then rub the capsules gently by hand 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 is usually high.
