According to my sources, we could find them in this areas. Bukidnon, Misamis Oriental and Davao. For last 4 years, a gatherer of Davao from my friend bought 2 sacks of this plants worth 500 pesos only. They sold them during the Cagayan de Oro City Fiesta but nobody recognizes it, most of the people here don't like forest plants they are just weeds into their sight. Those plants were left unsold until neglected and all died out which I'm trying to get all those for free but it's too late they are already gone.
