Different Flowering Strategies Ensure Reproductive Success in Two Coexisting Self-Incompatible Orchids. [PDF]

open access: yesEcol Evol
This 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.

Adaptive floral traits that impact stigma pollen load and seed production in Penstemon digitalis (Plantaginaceae)

open access: yesNordic Journal of Botany, Volume 2026, Issue 6, June 2026.
Penstemon digitalis is an early spring‐flowering species of the northwest Missouri prairie community, a period often characterized by low and unpredictable bee visitation. We conducted an experimental field study to evaluate how pollinator‐mediated pollen transfer and floral longevity interact to influence pollen acquisition and seed production.
