Typifications and new synonyms in Stachytarpheta (Verbenaceae) from Brazil

Abstract

We propose new synonyms and typifications for Brazilian taxa of Stachytarpheta (Verbenaceae). Twenty names are synonymized under the following accepted species: S. cayennensis, S. fiebrigii, S. gesnerioides, S. harleyi, S. hispida, S. indica, S. martiana, and S. reticulata. Lectotypes are designated for the following names: S. bicolor, S. bromleyana, S. crassifolia subsp. abairensis, S. elatior, S. gesnerioides var. cuneata, S. gesnerioides var. rotundata, S. glazioviana, and S. hirsuta. An epitype is designated for S. lanata, previously considered as a doubtful taxon and now treated as an accepted species, and also for S. restingensis. The necessity of such taxonomic and nomenclatural adjustments was noticed after the examination of a large set of herbarium collections (including the type specimens), specialized literature, and field observations. Our results support a forthcoming taxonomic treatment of the Brazilian Stachytarpheta.
