Lumnitzera rosea (Combretaceae) -- Its Status and Floral Morphology

Three forms of Lumnitzera (Combretaceae) are known to us in Queensland. Two are clearly the common and widespread mangrove species L. littorea, with scarlet flowers, and L. racemosa, with white flowers. The third form is intermediate (e.g., it has pink flowers) and is very local in distribution. The identity of this third form is the substance of this paper and is set against the background of a description of floral morphology and pollination biology in the genus.
