Pupulin, F. 2002. The Prosthechea prismatocarpa complex (Orchidaceae: Laeliinae) in Costa Rica, with a new species, P. tardiflora. Lankesteriana 3: 19—24.
Abstract.
The complex of Prosthechea prismatocarpa (Orchidaceae: Laeliinae) in Costa Rica is revised. A key to the species of the group is presented, together with their current taxonomy. A new species is described, P. tardiflora Mora-Retana ex Pupulin. The new species may be distinguished within the complex by the abbreviate rhizome, the inflorescence produced on the pseudobulb of the previous year, the non-fragrant flowers, the acute and basally reflexed sepals, the wide isthmus, and the short midlobe of the lip.
