Chromosome numbers in African and Madagascan Loranthaceae and Viscaceae

Abstract: Eighty‐five chromosome numbers representing about 63 species and 23 genera are reported for African and Madagascan Loranthaceae. The base chromosome number of all genera studied is χ= 9. This chromosome number also typifies all other Old World genera of the tribe Lorantheae, and thus supports the previously suggested thesis that the Asian and African Loranthaceae are relatively closely related. Seventy‐six chromosome numbers, representing three genera (Arceuthobium, Korthalsella, Viscum) and 40 species are rep… Show more

“…The unusual translocation heterozygosity in this species was previously described and illustrated by Wiens andBarlow (1973, 1975). Male plants were found to have a somatic chromosome number of 2n = 23, and at first meiotic metaphase the chromosomes consistently associated as seven bivalents and an open multivalent chain of nine chromosomes.…”

“…In other species of Viscum studied karyologically, there are no indications of identifiable sex chromosomes (Wiens and Barlow, 1971;Wiens, 1976). Sex is probably determined in a genetically simple fashion, as mentioned earlier.…”
