Discussion
In Florida, Rhabdadenia biflora occurs from Brevard and Charlotte counties southward.
F. Lens et al. (2009) have shown that Rhabdadenia biflora exhibits an interesting developmental plasticity in its ability to switch abruptly between wood anatomical features characteristic of erect or suberect species (vessels in radial multiples) and those characteristic of lianas (vessels in clusters).
Selected References
None.
