Table S1: Inventory of the introduced plants of Madagascar. “Introduced plants" are here defined as non-native plants presumably introduced by humans (directly or indirectly). Codes explained at end of table. Tropicos Madcat categorization (*'cultivated' usually comes from Perrier's Family notes to genus or binomial name Alien/ Known (following Genus / species (Tropicos family; not species [if blank not in Perrier's native invasive Note / comment for publication (e.g. Tropicos) or best we can determine) entry) Perrier] category status status Source issue with identification and classification) Acanthaceae indigenous non- Asystasia Juss.

Acer negundo L. not listed C S Chose 'N' for our category due to Binggeli reference (over Decary); Samyn cites Agave rigida as spontaneous (but this name is Agavaceae ambiguous according to ARS-GRIN).

Note that Tropicos MadCat has inconsistent treatment of A. viridis L. which it considers synonym of A. blitum subsp. emarginatus (which it designates as indig non endem) but A. blitum is designated naturalised.
