Here is a shot from this afternoon of a female Nepenthes ventricosa flower, from a plant that I grew from a seedling on a windowsill back in 2004-05. It stopped "pitchering" and attempted to flower a few months back; the bloom aborted for some odd reason -- and the plant has since grown another 40 centimeters or so of vine and sent up a second stalk . . .
