Nepenthes ventricosa

Nepenthes ventricosa (; from New Latin "ventricosus" "having a swelling on one side") is a tropical pitcher plant endemic to the Philippines, where it is a highland species, growing at an elevation of above sea level. It has been recorded from the islands of Luzon, Panay, and Sibuyan. The pitchers are numerous, growing up to tall and ranging in colour from ivory white to red.
"Nepenthes ventricosa" is very closely related to both "N. burkei" and "N. sibuyanensis", but can be distinguished by a more waisted middle to the pitchers, a smaller mouth, and, generally, a thinner peristome.
