The density of epiphytic bacteria on (1) leaves, (2) stems and petioles, and (3) whole shoots of submerged Nasturtium officinale, Apium nodiflorum and Glyceria fluitans was determined from January to June 1984 in a calcareous stream in North Humberside. The density on leaves was less than on stems and petioles; reasons for this are suggested. The density on all three species decreased from late January to February‐March and then increased to June. This temporal change was related to environmental variables (e. g. negative correlation with discharge and positive correlation with temperature), a situation which contrasts with Baker & Orr (1986) who found no such relationships in a Southern England chalk stream.
