 "N. × cincta" is one of only three known natural hybrids involving "N. northiana", the others being "N. × bauensis" and a cross with "N. mirabilis".The traits of "N. albomarginata" are very dominant in this hybrid; the wide flared peristome of its larger parent species ("N. northiana") is almost completely lost.Pitchers are narrowly infundibulate (funnel-shaped) throughout and range in colouration from cream to dusky purple with red or black spots.
