Flowers were a light pink colour, no strong scent.

Floral Morphology and visitations:

Each "flower-like" structure in fact contains several (approx. 5) styles (and ovaries). "Petals" are actually modified stamen ("petaloid stamenoids"). This increases efficiency of pollination one animal could potentially visit 4-5 genetically different flowers in one visit. Stamen encircle each individual ovary in several rows. True petals are brown and do not protrude far from sepals around the entire structure.

Pollen Morphology:

High levels of pollen present but difficulties in our extraction technique showed little pollen on slide. Pollen shape is small, round (pictured).

Nectar Characterisation:

The flower appears to have little nectar. From the flower's structure and size it can be inferred that this species' primary pollinators are insects, which would only be able to carry a small volume of nectar. So it is possible that the flower produces a small volume of highly concentrated nectar, rather than producing copious amounts of dilute nectar.
