| An unusual type of trichome is described for Anaxagorea (Annonaceae). On top of the stalk cell, extremely thinwalled cells form single, branched or stellate trichomes. The terminal cell(s) always end bluntly. When the thinwalled cells have been shed, the thick cuticle of the stalk cell remains as a cylindrical scar. Until now, this trichome type has not yet been found in other annonaceous genera. Our data contradict reports of other authors (Jovet-Ast 1942, Kramer 1969, Roth 1981) with regard to occurrence and structure of hairs in Anaxagorea. |
