Systematic Botany, 1991
Patterns of morphological variation within the Tolumnia variegata complex of Puerto Rico, Hispaniola, and Cuba are described. Univariate and multivariate analyses of population data obtained from fresh material collected in Puerto Rico and the Dominican Republic indicated that three a priori groups (Puerto Rican spring- and fall-flowering populations ...

The effects of a rust infection (Sphenosphora saphena, Basidiomycetes) on several fitness components of the orchid Tolumnia (Oncidium) variegata were quantified in a subtropical moist forest of Puerto Rico. Infected and uninfected plants of two size categories were observed and manipulated by increasing natural levels of fruit production to determine ...

Symbiotic seed germination is a critical stage in orchid life histories. Natural selection may act to favor plants that efficiently use mycorrhizal fungi. However, the necessary conditions for natural selection – variation, heritability, and differences in fitness – have not been demonstrated for either orchid or fungus.
