SE Asia mainland is a very rich area for some Araceae genera especially Amorphophalus and Typhonium which prefer seasonal conditions. Over the last two decades many new species of these two genera have been described from this region, particularly Thailand and Laos (Hetterscheid et al., 2001; Hetterscheid, 2006; Hetterscheid & Galloway, 2006; Murata et al., 2010). The total number of described species for Amorphophallus now exceeds 200 and the number of described species for Typhonium now exceeds 70. Fieldwork in Laos and Thailand by the author, starting in 1999 and still ongoing, continues to yield new species of Amorphophallus and Typhonium. Sample specimens of these species have been grown by the author. Repeated growth habits and flowerings have been observed for these new species and their descriptions are presented here.
