Skog, L. (1984). A REVIEW OF CHROMOSOME NUMBERS IN THE GESNERIACEAE. Selbyana, 7(2/4), 252-273. Retrieved from https://journals.flvc.org/selbyana/article/view/120658


Of the 135 known genera of the Gesneriaceae, 71 have had a count made of the chromosome complement ofat least one species. A few genera are well known cytologically relative to the number of species, e.g., Streptocarpus, Columnea, Sinningia, etc. This knowledge reflects the fact that workers have specialized in certain genera and that the well-known genera have received particular attention due to their horticultural value. Other genera, e.g., Cyrtandra and Besleria in particular, have had little study relative to the numbers of known species. These two genera, each having hundreds of species, have had only a few counts made. They have little horticultual potential and thus are seldom grown in cultivation for counts to be made from living plants.
