  abstract = {{W}e characterized the flowering patterns of 45 epiphytic orchid species occurring in {C}ameroonian rainforests to explore the environmental and evolutionary forces driving their phenology. {W}e used a dataset of 3470 flowering events recorded over a period of 11 years in the {Y}aounde living collection (82% of the flowering events) and from in situ observations (18% of the flowering events) to (i) describe flowering frequency and timing and synchronization among taxa; (ii) test flowering patterns for phylogenetic relatedness at the generic level; and (iii) investigate the spatial patterns of phenology. {A}n annual flowering pattern prevailed among the species selected for this study. {T}he species-rich {A}frican genera {A}ngraecum and {P}olystachya are characterized by subannual and annual frequency patterns, respectively. {H}owever, in terms of flowering time, no phylogenetic signal was detected for the four most diverse genera ({A}ncistrorhynchus, {A}ngraecum, {B}ulbophyllum, and {P}olystachya). {R}esults suggest also an important role of photoperiod and precipitation as climatic triggers of flowering patterns. {M}oreover, 16% of the taxa cultivated ex situ, mostly {P}olystachya, showed significant differences in flowering time between individuals originating from distinct climatic regions, pointing toward the existence of phenological ecotypes. {P}henological plasticity, suggested by the lack of synchronized flowering in spatially disjunct populations of {P}olystachya, could explain the widespread radiation of this genus throughout tropical {A}frica. {O}ur study highlights the need to take the spatial pattern of flowering time into account when interpreting phylogeographic patterns in central {A}frican rainforests.},
