Name derivation:
Wurmbea name after Friedrick Wilhelm von Wurmb, merchant and botanist in 18th century Batavia (Jakarta). Latifolia from the Latin 'latus' meaning broad or wide and 'folium' meaning a leaf; referring to the species broad leaves. Vanessae named after Vanessa, the author's wife and companion on many field trips.
Distribution:
Found along the coast from Eyre Peninsula, Kangaroo Island, Mount Lofty Rages and the South-east in south Australia, growing in low scrub on exposed sites. Also found in Victoria and Tasmania.
Status:
Native. Rare in South Australia. Very rare in Tasmania. Uncommon in Victoria.
Plant description:
Doecious herbs to 15 cm high. Leaves 3, lower 2 similar, close together or separated, narrowly to broadly linear, or lanceolate, to 12 cm long and 8 mm wide, margin serrated, lowest leaf basal and not dilated, middle leaf more erect and sometime dilated at the base, upper leaf smaller, dilated at the base with short erect apex. Inflorescence spike with 2–9 white or pink flowers, tepals elliptic shortly fused basally, spreading, white, nectary 1 per tepal, situated about one-third from base of tepal, white or faint violet, raised, often with a narrow central beak, anthers purple. This subspecies differ from the other subspecies found in South Australia by the relatively longer, less broad and  not opposite leaves, female flower spikes spike not dense and exserted on a scape at least 2 cm long and capsule oblong. Flowering between July and September.
Fruit type:
Brown papery oblong capsule containing many seeds.
Seed type:
Brown globular seed to 1.5 mm diameter.
Embryo type:
Linear under-developed.
Seed collecting:
Collect mature capsules, those turning pale straw colour and containing hard brown seeds. 
Seed cleaning:
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:
From three collections, the seed viability was high, ranging from 95% to 100%.
