This is consistent with additional anatomical characters that support a close relationship between Aristolochia and Holostylis (Solereder, 1889a; Carlquist, 1993) especially the presence of idioblasts filled with brown, tanniferous material in Holostylis (Solereder, 1889a) and at least in one species of its sister group such as A.
The following types of secretory structures have already been recorded in the family: trichomes, idioblasts, laticifers, coletters, nectaries, secretory cells with resinous contents, tannin cells, and mucilage lacunae (Solereder 1908; Metcalfe and Chalk 1950; Thomas 1991).
Also, idioblasts (Norstog & Nicholls 1998, Jones 2002) and occasionally isolated cells (Acuna-Castillo & Mann-Mendez 2012) with thickened secondary walls can be found in the mesophyll.
