No end to endemism - contributions to the difficult Nasa Weigend Series Alatae (Loasaceae). A new species from Peru and the rehabilitation of " Loasa" calycina Benth.

ABSTRACT: A new species of Nasaser.Alatae (Urban & Gilg) Weigend from Northern Peru is described and illustrated. Nasakatjae sp. nov. was at first encountered by an observation on iNaturalist and subsequently collected in the humid Andean forests near Colasay in the province of Jaén (Cajamarca, Peru). Whilst comparing the new species with closely related Nasaloxensis (Kunth) Weigend, a taxon widespread in Southern Ecuador (and tentatively adjacent Peru), a reevaluation of the status of earlier synonymized Loasacalycina Benth. became necessary. Consequently, Nasacalycina comb. nov. is rehabilitated at species level and Nasaloxensis is redefined.
