Remarks.

C. septadentata was found on marginal rocks of small streams and on rocky seepages (large exposed rock in the middle of the forest), from 1045-1580 m a.s.l., extending slightly the altitudinal range of this species. Environmental characterization: Water temperature 15-17 °C; dissolved oxygen 8.6-10.2 mg.l-1; pH 5; moderate to fast flowing; vegetal canopy reduced or absent (less than 30% covered). The species was found in PARNASO (Rio de Janeiro State) and PESM ( São Paulo State). Low altitudinal specificity (IndVal: 0.09; p = 0.88).
