LECTOTYPIFICATION OF TRITICUM-TURGIDUM AND T-SPELTA (POACEAE)

The protologues of Triticum turgidum L. and T. spelta L. each show unc ertainty in the Linnaean concept of Triticum species but pose differen t problems for typification. In the case of T. turgidum, Bowden's lect otypification by the specimen Herb. Linn. No. 104.2 (LINN), designated apparently on the basis of its Linnaean notation ''turgidum 3'', is i n error. Both elements on that sheet are forms of T. aestivum and neit her can be accepted as being part of the original material for T. turg idum. The various elements of the protologue are discussed and a Royen specimen is designated as lectotype of T. turgidum, thereby avoiding a major destabilization of Triticum nomenclature. For T, spelta, the o riginal Linnaean concept includes T. dicoccum Schrank ex Schubler. Cur rent usage of T. spelta is maintained by designating a Linnaean specim en of T. spelta at LINN as the lectotype.
