FIG. B1. Flowering phenology of E. zeyheriana overlaps broadly with that of W. cuspidata at both (A) the Mt. Gilboa site and (B) Cobham. Samples include herbarium specimens (unhatched; E. zeyheriana: ngilboa = 8, ncobham = 16; W. cuspidata: ngilboa = 0, ncobham = 4) and field observations where herbarium specimens could have been made (different localities and/or dates) during the course of this study (hatched; E. zeyheriana: ngilboa = 10, ncobham = 17; W. cuspidata: ngilboa = 16, ncobham = 19). Each bar represents a period of ten days. Median flowering dates for Gilboa are 18 June vs. 22 June for E. zeyheriana and W. cuspidata respectively. For Cobham, medain flowering dates are 13 June vs. 22 June for E. zeyheriana and W. cuspidata respectively.
