Unraveling the story behind the Linnaean basionym of Bouchea prismatica : Revised typification of the name Verbena prismatica

The typification of the Linnaean name Verbena prismatica is revised. A previous neotypification is investigated and it is shown that the choice of Moldenke (Herb. Linn. No. 35.3) must be superseded since a sheet comprising original material has been located in the Linnaean collection at S. The protologue is shown to have comprised a mixture of two elements, one corresponding to Salvia occidentalis and to the traditional concept of V. prismatica (i.e., Bouchea prismatica ). A lectotype is selected that preserves the current application of the name to a species of Bouchea .
