title: Data from: Global biogeography and macroevolutionary patterns of angiosperm inflorescence types

description: The huge variety of inflorescences plays an important role in the
 reproductive success and diversification of flowering plants. However, the
 influence of climate on inflorescence diversity at macroecological and
 macroevolutionary scales remains poorly understood. In this study we map
 the global spatio-temporal pattern of inflorescence types and investigate
 the influence of climate on the spatiotemporal patterns of angiosperm
 inflorescence diversity. Our results reveal a clear latitudinal trend in
 inflorescence types, with indeterminate inflorescence frequency increasing
 away from the equator. Pollination mode composition and temperature
 variables are strong correlates of the geographic variation in
 inflorescence type frequency. We further reveal that lineages with
 determinate inflorescence have significantly higher net diversification
 rate than those with indeterminate inflorescence. The frequency of
 evolutionary transitions from indeterminate to determinate inflorescences
 consistently decreased during the Cenozoic. Significantly, the
 evolutionary dynamics of inflorescence types during the Cenozoic show
 clear latitudinal differences: the proportion of indeterminate
 inflorescence at high latitudes increased with time and with the decline
 of paleo-temperature, while that at middle to low latitudes decreased.
 These results indicate strong climatic forcing on floral dynamics via
 influencing inflorescence types and their coevolution with animal
 pollination over large biogeographical and macroevolutionary scales.
