Notes: Alocasia cf. zebrina; fruiting plant. Leaf looks similar to A. sinuata but the petiole is similar to A. zebrina
However, the leaf margin is sinuate and the presence of silvery patches on the leaf indicates that it is not A. zebrina or it is just a result of environmental conditions since the area is the site of a geothermal plant?

Image 1: Alocasia wenzelii in situ, Samar Island, Philippines. Those leaves are over three feet long- way longer and bigger than Alocasia zebrina's, and the petiole markings don't reach all the way up to the apices of the petioles (many still consider them conspecific, but then again many who think of them that way have not seen the two alive, in their natural habitat). (Suarez, W.)
