Discussion
Syrrhopodon incompletus is a variable species and the variation has been sorted out as varieties. Within our flora area we have var. incompletus (FIG. 55A-F), var. berteroanus (Bridel) Reese [Syn.: S. berteroanus (Bridel) Muller Hal.] (FIG. 55G-H), and var. luridus (Paris & Brotherus) Florschiitz. The var. incompletus (from all local habitats) has mostly paired teeth on the upper leaf margins and only slightly flaring leaf shoulders without elongate cells between the cancellinae and margin; var. berteroanus (from atop Mont Galbao at 700 m) has mostly single teeth on the upper leaf margins and strongly flaring leaf shoulders; var. luridus (at 200-300 m) has mostly paired teeth on the upper leaf margins and strongly flaring leaf shoulders with conspicuous elongate cells be¬tween the cancellinae and margin.
