Abstract

Calandrinia speciosa Lehm. and Calandrinia spectabilis Otto & Dietr. are 1830s-vintage validly-published names of Chilean plant species evidently pertaining to taxa currently classified in Cistanthesect. Cistanthe (Montiaceae). The taxonomic status of both names is problematic, because they were not typified or illustrated, their precise Chilean provenance is unknown, and their diagnoses/descriptions might apply to more than one species. Both names have been and continue to be applied taxonomically haphazardly. The existence of two later conceptually heterotypic synonyms of C. speciosa Lehm, viz. C. speciosa Lindl. non Lehm. and C. speciosa Hook. non Lehm., has exacerbated the confusion. The present work summarizes the history of the application of these names in botanical taxonomy and horticulture. Both likely, but not unequivocally, refer to plants of the later-described, typified, and otherwise well-documented species Calandrinia laxiflora Phil. [≡ Cistanthe laxiflora (Phil.) Peralta & D.I. Ford]. But persistent ambiguities justify proposals to reject both C. speciosa and C. spectabilis.
