Clock-dated phylogeny for 48% of the 700 species of Crotalaria (Fabaceae–Papilionoideae) resolves sections worldwide and implies conserved flower and leaf traits throughout its pantropical range

Table 2 The 14 Köppen-Geiger climate categories and their grouping into four major climate groups (rightmost column)

Precipitation criteria reflect annual accumulated precipitation (P_ann), monthly precipitation in driest (P_min) and wettest (P_max) month, for the summer and winter half-years on the hemisphere considered (P_smin, P_smax, P_wmin, P_wmax) and dryness threshold (P_th, only for Arid). Dryness threshold (mm) depends on annual temperature and annual cycle of precipitation. Temperature criteria depend on annual mean near-surface temperature (T_ann), monthly mean temperature of warmest (T_max) and coldest (T_min) months, and monthly temperature (T_mon). (See [31])
