Two new species of Calceolaria L.(Scrophulariaceae) from the tropical Andes are de-scribed: Calceolaria rhombifolia Molau from north-ern Peru and C. urticifolia Molau from northernBolivia, belonging to the sections Rotundifoiiae andUlrticopsis, respectively, within subgenus Calceolar-ia. This paper is the first addendum to the 1988monograph in Flora Neotropica.REIKSIMN. Se describen dos nuevas especies deCalceolaria L. (Scrophulariaceae) de los Andestropicales: Calceolaria rhombifolia Molau del nortede Perui y C. urticifolia Molau del norte de Bolivia.Pertenecen a las secciones Rotundifoliae y U(rticop-sis, respectivamente, dentro del subgenero Calceo-laria. Este articulo es la primera adenda a la mon-ografia de Flora Neotropica de 1988. Key words: Bolivia, Calceolaria, Peru, Scro-phulariaceae. Calceolaria L. (Scrophulariaceae) is a Latin American genus of approximately 250 species ranging from Mexico to Tierra del Fuego. In the most recent monograph of the Neotropical repre-sentatives of the genus (Molau, 1988), 183 species were recognized in the Neotropical part of its dis-tribution area. With the present circumscription. the genus comprises 3 subgenera and 22 sections (Molau. 1988). Nearly all of the Neotropical species belong to the subgenus Calceolaria, whereas the vast majority of the southern temperate species be-long to the subgenera Cheiloncos and Rosula. Since the 1988 monograph, a lot of new Calce-olaria collections from the Neotropics have accu-mulated. However, most of these are from previ-ously relatively well-known parts of the Andes, andonly little among the accessions has so far calledfor an update of the monograph. There are huge"white spots" in the tropical Andes still awaitingprimary botanical exploration. and it is sympltom-atic that only the collections of field parties workingin remote and poorly explored areas have broughtin Calceolaria collections that add to our knowl-edge of the genus. Most important of these are thegroups of Isidoro Sanchez Vega and collaborators(Cajamarca) and Ahundio Sagastegui A. et al. (Tru-jillo) operating in northern Peru, and Stephan Becket al. (La Paz) undertaking fieldwork in northernBolivia. In addition, the fieldwork of the late DavidN. Smith from many remote parts of the PeruvianAndes has yielded an important set of Calceolariaspecimens, in some cases the first modern collec-tions of species that were previously known onlyfrom the type collection. The collecting activity ofthe above-mentioned parties has provided materialthat now calls for taxonomic recognition. The twospecies described here are the first addendum tothe 1988 monograph; both belong to subgenus Cal-ceolaria.Calceolaria rhombifolia Molau, sp. nov. TYPE: Peru.
