I bought a plant labelled N. Ventricosa/Burkei Complex from Peter
D'Amato. This plant does seem different from my N. ventricosa.
It is a much smaller plant: the leaves on my plant are perhaps 2 inches
long and the pitchers are roughly the same size. The pitchers are
Red and Green. The top part of the pitcher is red and an almost
horizonal line ends the red. The rest of pitcher is green.
