Taxonomy question
I have what was labelled as Polygonum bistorta 'Superbum' in my garden.
The RHS does not have it listed but does have Persicaria bistorta 'Superba'. Are they the same thing? What is the correct current taxonmy of this plant? I assume that somewhere along the line the name has changed but need to know which is the right name. As the 03/04 Plantfinder has it has P. bistorta 'Superna' that that is the right name. If so then what happened to Polygonum? Many thanks P. |

The picture is of a 'vigorous, clump-forming perennial that from arly to late summer produces spikes of soft pink flowers above oval leaves.' It grows to about 2.5' and spreads to about 2'. This copy was published in 1989. The 1999 version says "Persicaria bistorta syn. Polygonum bistorta 'Superba' and to me, the two pics look identical.

As the 03/04 Plantfinder has it has P. bistorta 'Superna' that that is the right name. If so then what happened to Polygonum? Polygonum has been chopped into pieces (as per Cornus and Chyrsanthemum). The less drastic version - which appears to be what PlantFinder is using - has Polygonum, Persicaria and Fallopia (the latter includes Japanese Knotweed). The more drastic version adds Aconogonum, Koenigia and Bistorta, and perhaps other genera; in this versions Polygonum bistorta aka Persicaria bistorta becomes Bistorta officinalis. The best reference I could find online was from "Contributions to the Flora of Hawaii". It reads "The genus Polygonum has presented taxonomic problems since its establishment by Linnaeus in 1753. In the ensuing years, several authors have attempted to divide the genus into more natural units, the most recent being Louis-Philippe Ronse Decraene who chose to investigate the floral morphology of the genus as a research topic for his Master of Science degree in plant taxonomy. His data supports the division of Polygonum into two tribes containing ten genera, a classification that is gaining wide acceptance." The family boundaries in that area have also been revised - see the April 2002 issue of Fremontia for an overview (URL:http://www.cnps.org/ publications/Fremontia_Vol30-No2.pdf) -- Stewart Robert Hinsley |

In those days it was spelt Pomfadog, so you can guess, it was renamed in out vocabulary from Pom-FAdog to Pomfa-dog, which name later slid off the Welsh mountains on to our bull terrier.... -- Rusty Open the creaking gate to make a horrid.squeak, then lower the foobar. http://www.users.zetnet.co.uk/hi-fi/ |

Does indeed. It may be that altering "Superbum" to "Superba" is a falsification. Well, it might confuse it somewhat. And find itself with diminished attraction in the Mardi Gras Parade..... -- Rusty Open the creaking gate to make a horrid.squeak, then lower the foobar. http://www.users.zetnet.co.uk/hi-fi/ |
