Table 3 in Molecular phylogenetic data and seed coat anatomy resolve the generic position of some critical Chenopodioideae (Chenopodiaceae - Amaranthaceae) with reduced perianth segments

Table 3. Additional noteworthy characters evolved in Blitum and Oxybasis. This table summarises life history and carpological data from Sukhorukov and Zhang (2013), Sukhorukov et al. (2013), Sukhorukov (2014), with additional information included for Blitum virgatum subsp. montanum and B. korshinskyi.
