Ecology and distribution
Trop. Afr.
Biology : Differs from Scilla by: leaves usually spotted, inflorescences ± flexuous (usually 2 or more), flowers usually purplish to greenish, ovary stipitate. However, “the morphological distinction between Ledebouria and Scilla…becomes less clear when material from tropical Africa and the Mediterranean is included” (Stedje, 1998: 4); “but as these small differences get support from the DNA sequence data I will suggest that Ledebouria and the sub-Saharan species of Scilla should be treated as two separate genera. Ledebouria is closest related to the tropical African species of Scilla, and appears to have a common ancestry” (Stedje, o.c.: 8).
Ecology : The genus is very variable in leaf characters, chromosome numbers and karyotypes. The species boundaries are often obscure, and species delimitation has often been based on single characters.
