Taxonomy

2. Of the three duplicates of Lörzing 6573, the sheet with both male and female inflorescences is the lectotype. The Lörzing number ‘6802’ in is an error for 8602, as shown in the caption to f. 23 (1928). 1 Nepenthes tobaica was long confused with N. mikei. The last can be distinguished by its fasciculate or branched pitcher spurs, its broader peristome (2.5 mm vs. 0.5-1 mm wide) and its shorter inflorescence (7-15 cm vs. 15-35 cm) with 1-flowered, not 2-flowered, partial peduncles. Nepenthes tobaica is sometimes also confused with N. reinwardtiana but can be distinguished by the absence of pitcher ‘eye-spots’, the presence of tufts of white hairs in the leaf axils, and the rounded stem with non-decurrent leaf bases.
