Underwater cross pollination (hypohydrophily) represents a markedly divergent form of pollination in seed plants; reproductive structures are functionally wet during pollination. Callitriche (Callitrichaceae) is the only genus in which both aerial pollination systems and hypohydrophily are reported. This diversity in pollination types would not be predicted based on the general uniformity in floral structure in the genus. Logistic difficulties in conducting experimental pollination studies in C. hermaphroditica have plagued actual confirmation of hypohydrophily. Evidence from paternity exclusion analysis using random amplified polymorphic DNA markers is presented that confirms hypohydrophily in C. hermaphroditica.
