Definitions for "Plantyn"
Plantyn (Anglicized form of Plantijn) was one of three Dutch hybrid elms released in 1973, but was to prove no more resistant to Dutch elm disease than its contemporaries Dodoens and Lobel. Derived from a crossing of the Dutch hybrids 202 (U. glabra Exoniensis × U. wallichiana) and 302 (U. minor 1 × U. minor 28), it was nevertheless to prove of great significance in later developments. A selfed seedling was to become the first Dutch clone to prove immune to disease, released in 1989 as Columella.
