Different Flowering Strategies Ensure Reproductive Success in Two Coexisting Self-Incompatible Orchids. [PDF]
Ecol EvolThis study compares the reproductive strategies of two self‐incompatible orchids, Pholidota articulata (mass‐flowering) and Coelogyne prolifera (steady‐state flowering). Despite differences in pollinator visitation and pollinia transfer efficiency—higher in P. articulata—both species achieved similar natural fruit set rates over 3 years.
