Abstract

Brassia gireoudiana Rchb.f. is treated as a subspecies of B. verrucosa Lindl. because of apparent hybridization in Costa Rica. Trichocentrum stipitatwn (Lindl.) Chase & N.H. Williams is treated as a subspecies of T. nudum (Batem. ex Lindl.) Chase & N.H. Williams because of an area of intergradations in the Perlas Archipelago and Panamá province. Reflecting recent work in DNA analysis, new combinations are published in Cuitlauzina for four species previously treated as Osmoglossum or Palumbina. Odontoglossum leucomelas Rchb.f., a close ally of Oncidium stenoglossum, is transferred to Oncidium.
