I'll also add to what Cliff said by saying that ampullaria will produce basal
rosettes anywhere along the length of the vine...as the ampullaria vine grows
upwards and larger, basal rosettes can suddenly appear anywhere along its
length...so although its rather rare that uppers are produced, the basal
pitchers (misnamed perhaps??) can cluster high up on the vine.
