Table 2.
Results of controlled pollination treatments and values of indexes that describe the breeding systems of four epiphytic Werauhia species (Bromeliaceae: Tillandsioideae) in a montane forest, Cerros La Carpintera, Costa Rica. Data are fruit percentages (%) and in parenthesis the number of developed fruits/manipulated flowers.
