Nepenthes mikei is a beautiful highland tropical pitcher plant discovered in 1989 by Bruce Salmon, Ricky Maulder, and Mike Hopkins on an expedition to Mount Pangulubao in Sumatra. The plant was first published as Nepenthes sp. ‘New Species’ (I wonder how many plants have had that name) in a 1990 issue of the Carnivorous Plant Newsletter, managed by the International Carnivorous Plant Society. Our intrepid explorers described the plant thusly:
We saw another Nepenthes that is different than the others we saw in the higher highland areas. It has small pitchers slightly similar to N. tentaculata, N. tobaica and N. gracilis but tougher and thicker. The pitchers are always nicely colored with blackish lines and markings similar to N. fusca. There was very little variation with this species as all mature plants had ample rosettes on the ground and also at intervals up the stem. The stems were climbing [sic] up to about 7 meters and had upper pitchers similar in color and shape to the lower pitchers but with the usual differences. The male inflorescences were about 20 centimeters, peduncle inclusive.
Prior to a formal description, Nepenthes mikei was known as N. minutissima among growers. This name is a nomen nudum, or “naked name” – a placeholder used until a formal description occurs and proper name prescribed.
Ricky Maulder and Bruce Salmon formally described Nepenthes mikei in a 1995 issue of the Carnivorous Plant Newsletter. The herbarium specimen B.Salmon & R.Maulder 221719 is located at the Auckland Institute and Museum in New Zealand and is the holotype, or singular specimen used as the definitive example of a given species at the time of its description. The sacrificial holotype plant was prepared in 1995 from a specimen cultivated in New Zealand, and includes a vine with a rosette, a lower pitcher, and a female flower.
