• The leaf-like bracts on this cone are almost indistinguishable from the normal vegetative leaves, except they are more curved towards the stem.

• When receptive, the stigmas release a species-specific fragrance, and the bracts in the neck of the inflorescence loosen, allowing the pollinators to enter.

• In each experimental patch, 10 plants had a red bract added, 10 plants had a green bract added and five plants had no bract.

• For each bract treatment values for the species are means of three temperatures.

• Individual growth was measured as the number of new leaves and floral bracts produced per individual.

• On female trees each inflorescence is solitary and consists of a single pedunculate flower surrounded by a whorl of bracts c. 7 mm long.

• On the male trees inflorescences are often in fascicles, and with each inflorescence a whorl of bracts surrounds a capitulum of apetalous male flowers.

• The bracts are red and flower colour is uniformly violet.

• The hibernacula are located in flower bracts, under lichens, loose bark and on other tree parts, which are relatively exposed to ambient weather conditions.

• In both seasons, seeds were germinated either in their fruiting bracts (fruits) or after handremoval of the fruiting bracts.
