Leyland cypress has a new name
Leyland cypress?s botanical name has been changed from x Cupressocyparis leylandii to x Cuprocyparis leylandii and Nootka cypress?s name has been changed from Chamaecyparis nootkatensis to Xanthocyparis nootkatensis.
These changes occurred after a new species of conifer was discovered in Vietnam, giving rise to a new genus. Golden Vietnamese cypress or Xanthocyparis vietnamensis is the first new conifer genus to be found since Wollemia nobilis was discovered in Australia in 1994 and only the third since 1948.
The tree was found growing on a rugged limestone ridge in 1999 by a team of botanists from Russia, the UK, USA and Vietnam. Samples were confirmed that the plant was a species new to science by Ajos Farjon, Taxonomist for Gymnosperms at the Royal Botanic Gardens in Kew.
Scientists also demonstrated that Nootka cypress is distinctly different from other members of the Chamaecyparis genus and realized that it is closely related to the new Vietnamese conifer. It has been transferred from the Chamaecyparis genus to the Xanthocyparis genus.
Leyland?s name had to be changed because one of the parents of this hybrid is the Nootka cypress.
While they made the transfer on paper easily, it will be a long time before it becomes common knowledge. I suggest that you list these at their correct new home in your catalog, but keep the old name with a statement of (See the new name. The name has been changed).

The Plant Patents Website as of 2-07 is http://www.uspto.gov/patft/index.html, and is useful when you know the plant patent number.
But something new is at Google. Just above the blank space intended for us to type a word, a subject or a question is a line with several words (web, images, video, news, maps, and the word more. Click on ?more?. Then click on the word ?patents? when it appears in a list.
In the blank space, type the cultivar name, the complete common name or the complete botanical name with cultivar name, or the patent number. The best method is to type the complete botanical name with the cultivar name. Or type the number this way (PP13098).
