OCCURRENCE OF THE ROTIFER, HABROTROCHA CF. ROSA DONNER, IN THE PURPLEPITCHER PLANT, SARRACENIA-PURPUREA L., (SARRACENIACEAE) ALONG THE EASTERN SEABOARD OF NORTH-AMERICA

Sarracenia purpurea L, plants were studied in seven bogs along the eas tern seaboard of the United States from New Jersey to Georgia. Water s ampled from 225 leaves was found to contain several invertebrates. A s ingle bdelliod rotifer, a form of Habrotrocha cf. rosa Donner very sim ilar to that described by Bateman (1987) in S. purpurea in western New foundland, was identified in 70% of the leaves. Investigations are in progress to examine the possibility that this strong association indic ates H. cf. rosa is specific to S. purpurea.
