Conservation
Least Concern due to its distribution and common habitat
Note
See also notes under C. tenuispica, with which there is much confusion. This taxon looks quite similar to C. haspan, with the only real difference being the shortlived (‘annual’) status with the lack of rhizome or stolons. There is some confusing variability within this taxon: there are specimens which are indistinguishable apart from the number of stamens, e.g. Katende 622 from U 4 and Luke & Mbinda 5771 from K 7; in the first there are 3 stamens (and slightly tuberculate nutlets), in the second there are 2 (and ± smooth nutlets). A third specimen, also from U 4, Langdale-Brown 2276, has 3 stamens – and ± smooth nutlets! Within Liben 846 from Rwanda there are 2 or 3 stamens within the same collection, with no other visible difference in the specimens.
