it shows other characters. It is a fragment of the lower portion of a climbing stem; this stem and its leaves are like those of the first mentioned plant, but the pitchers differ from those of N. sanguinea only by the toothed interior margin of the peristome. When the latter character had been absent, I should not have hesitated to record N. sanguinea as occurring in Sumatra; also the provenance of the two mentioned plants from probably the same habitat has kept me from doing this. Of course it is possible, that both plants of Junghuhn represent a new species, but since the material at hand shows only characters intermediate between two species already known and between many related species intermediate forms have been found, I prefer to distinguish also these plants as such. It is very improbable that it is a hybrid, since pure N. sanguinea has not been found in Sumatra, and from the region where Junghuhn collected his plants N. singalana too has not been recorded. As is obvious from a letter written by Macfarlane and extant in the Leiden Herbarium this author intended to make a description of N. Junghuhnii for Koorders to be published in his Plantae Junghuhnianae lneditae, but apparently it had not come to that. The publication of Ridley, not written in Latin, is invalid from a nomenclatorial point of view. Danser treated N. junghuhnii as a possible natural hybrid between N. singalana and N. sanguinea. The latter species is now known to be absent from Sumatra. References Clarke, C.M. 2006. Introduction. In: Danser, B.H. The Nepenthaceae of the Netherlands Indies.
