Abstract
Summary: Three types of serological precipitin techniques were employed, using seed extracts from selected monocotyledonous species and antisera to Typha and Sparganium. The obtained protein data were evaluated for use in helping to determine the placement of the Typhales within the monocotyledons. Data indicated the following: (1) significantly high serological correspondence between Typha and Sparganium, supporting the placement of these two genera within the order Typhales; (2) low serological correspondence between the Typhales and Liliales (in addition to some anomalous activity), indicating possible distant evolutionary relationships between these two orders; and (3) little or no serological correspondence between the Typhales and most of the tested monocotyledons, reflecting an isolated position for the Typhales within the monocotyledons.
