Type: article

Abstract: Amorphophallus samarensis is described as a new species from Paranas, Samar Island Natural Park, Samar Eastern Visayas, Philippines. A. samarensis resembles A. calcicola by having a solitary leaf, long peduncled solitary flower, cylindric female zone, ovary depressed, disk shape, slightly distant ovaries, and absence of staminode. It differs from A. calcicola by having the rachis winged at the distal part of the leaf, pale to dark maroon slightly depressed globose capitate stigma, style color, length of spadix, and truncate anther. The new species is considered Critically Endangered (CR) based on IUCN guidelines due to persistent anthropogenic activities. There are 30 individual plants encountered in the locality with less than 100 sq. km area of occupancy with an observed threat.
