New taxa and combinations in Calceolaria (Scrophulariaceae) from Peru and Bolivia

As a result of field work in Peru and Bolivia 1982–83, and herbarium studies, 21 new taxa are described and two new combinations are made in Calceolaria. The following species are described as new: C. sclerophylla, C. arbuscula , and C. crassa of sect. Sa–licifoliae; C. rupestris of sect. Revolutae; C. micans, C. laevis, C. rariflora , and C. concava of sect. Teucriifoliae; C. bullata and C. neglecta of sect. Parvifoliae; C. amoena and C. ramosa of sect. Polyclada; C. pilosa, C. incana, C. hirsuta , and C. cordifolia of sect. Urticopsis; C. cumbemayensis of sect. Lobatae; and C. caespitosa of sect. Scapiflorae. Three new subspecies are described: C. deflexa R. & P. ssp. cuneata and C. salicifolia R. & P. ssp. nigricans of sect. Salicifoliae , and C. hispida Benth. ssp. acaulis of sect. Lobatae. Two new combinations are proposed: C. melissifolia Benth. ssp. pseudoscabra (Edwin) Molau of sect. Teucriifoliae , and C. llamaensis (Edwin) Molau of sect. Anacyrta. The taxon Revolutae is raised to the sectional level, and the sections Polyclada and Parvifoliae are emendated. Chromosome numbers are reported for C. sclerophylla (2n = 36), C. micans (2n = 72), C. laevis (2n = 72), C. melissifolia ssp. pseudoscabra (2n = 36), C. neglecta (2n = 36), C. cumbemayensis (2n = 36), and C. hispida ssp. acaulis (2n = 36).
