Status: Native
Description:
See C. caesius subsp. caesius. for general description of the species.
Notes: The species-group is characterized by having distinct swollen and fused lowermost internodes and pedicels. C. caesius sens. lat. (subsp. caesius and subsp. giganteus) shows great range of variation in habit and leaf size. Such characters are not fully correlated with each other and are certainly not correlated with any other character. Nevertheless, a reasonable number of specimens can be separated into those with delicate wiry culms and those with more robust culms by using lamina width. But there is a continuous range of variation in these and all other characters. The more robust plants (subsp. giganteus) are restricted to the northern, more tropical areas. Further studies are needed to ascertain whether the differences in habit between the two extremes of the range of variation are merely those of phenotypic plasticity or not. Lamina width can vary greatly in an individual and measurements should be taken of the widest leaves in a specimen.
