Abstract
Dracontium fuscopunctatum, a new species of Araceae—Lasioideae—Dracontieae from the lower montane forest at the eastern Andean slopes, in the province of Morona Santiago, southeastern Ecuador, is here described and illustrated. It is characterized by the tubercles produced on top of tubers within a depression with thickened raised-margins. The new species is also characterized by leaf blades with veins sulcate and scattered tufts with glandular trichomes adaxially, prominent black glands abaxially, inflorescence with a large spathe that has punctuations to short dark strikes at base and abundant epidermal raphides without, and flowers with stigma disciform, sessile. Dracontium fuscopunctatum, is assessed provisionally as Endangered.
