Notes

1 Nepenthes ventricosa is unlikely to be confused with the only other Luzon Nepenthes, N. alata. The angular stems and white, hourglass-shaped, upper pitchers of N. ventricosa make it easily distinguished. Nepenthes ventricosa is closely related to N. burkei of Mindoro and N. sibuyanensis of Sibuyan, but neither have the white, highly constricted pitchers of N. ventricosa. 2. Blanco’s types were destroyed at PNH, but duplicates may exist elsewhere (see notes under N. alata).
