Diverse fauna, but predominantly birds, set the fruits of Bromeliaceae (Table 6.1). However, few accounts provide the additional data necessary to determine how pollinators affect the structure of plant populations, in u-ence the quality of the resulting offspring, or affect the evolution of the ower. Gardner (1984, 1986a,b) conducted one of the most provocative inquiries, drawing on her extensive knowledge of Mexican Tillandsia. Other authorities choose various Pitcairnioideae, while Bromelioideae remain least studied of the three subfamilies. Gardner s descriptions and analyses provide a starting point to consider the breeding mechanisms of Bromeliaceae, but rst we need some background on this remarkable genus and its subfamily (Chapters 12 and 13).
