Hakea epiglottis, a relative of the Hakea laurina previously featured on BPotD, is endemic to Tasmania. These photographs are from early May of last year in UBC's Alpine Garden.
Though some references suggest that this species' common name is white hakea, most (if not all) Australian sites instead use beaked hakea – so my preference is the latter.
The Flora of Australia Online's record for Hakea epiglottis notes that most wild populations of the plant consists of plants with flowers that are either functionally male or functionally female. Exceptions do occur, though, where individuals have flowers that both produce viable pollen and form fruit. In other words, while a few plants are hermaphrodites, most are unisexual. The lead paragraph in the following paper discusses the advantages and disadvantages of being either hermaphroditic or unisexual: Fetscher, AE. 2001. “Resolution of male-female conflict in an hermaphroditic flower (PDF).” Proc. R. Soc. Lond. B. 268:525-529. It boils down to either conserving resources (hermaphroditism) or increasing the likelihood of outcrossing.
