Ij. Radford et al., CHROMOSOME COUNTS FOR THE AUSTRALIAN WEED KNOWN AS SENECIO-MADAGASCARIENSIS (ASTERACEAE), Australian systematic botany, 8(6), 1995, pp. 1029-1033
Chromosome counts of 2n = 20 for specimens of Senecio madagascariensis
from Australia and from Madagascar are reported. By contrast, counts
of 2n = 40 for a diversity of specimens of the S. lautus sensu late co
mplex are reported. These results support previous separation of these
taxa on morphological grounds.
