Appendix D
Maternal plant seed weight depends on seed type and source population. Cleistogamous seeds are universally lighter weight than chasmogamous seeds across all source populations (P < 0.05), but the differences in source population depends on seed type (P < 0.001). Letters indicate significant differences among source populations separately for each seed type. Source populations are organized from left to right by increasing latitude. FF = French Flat, WS = Whetstone, LT = Lower Table Rocks, HD = Hazel Dell, HR = Horse Rock Ridge, JF = Jefferson, SL = Sublimity, UW = Upper Weir.
