Taxonomy
This species is superficially reminiscent of K glomerata (especially in the leaves) and K. tomentella (as regards the conspicuous indumentum, falling off in pieces). Knema ridsdaleana is readily distinguishable by its grey leaf undersurface, with minute dark punctation (not to be confused with coarser dots, strong lens!), conspicuous indumentum, long-stalked (male) inflorescences, 4-merous perianth, with conspicuously shedded indumentum, and 11-13 large (long) ± contiguous subsessile 4-sporangiate anthers.
