• Pollen Production in the Androdioecious Datisca Glomerata (Datiscaceae): Implications for Breeding System Equilibrium 

  Philbrick, Tom; Rieseberg, L.H. (2005-02-01)

  Androdioecy (the presence of males and hermaphrodites in a breeding population) is a rare reproductive system in plants, with Datisca glomerata (Datiscaceae) representing the only well-documented example. Recent reports ...
• Exine Reduction in Underwater Flowering Callitriche 

  Philbrick, Tom; Osborn, J.M. (1994-10-01)

  Both aerial and underwater pollination systems (hypohydrophily) occur in Callitriche (Callitrichaceae), and as such the genus can serve as a model system in which to probe questions concerning the evolution of hypohydrophily ...
