Notes
1 Nepenthes gracilis is a widespread, common and weedy species. Nepenthes albomarginata and particularly N. reinwardtiana have often been confused with N. gracilis. From N. albomarginata, N. gracilis is told apart by the triangular stems, the decurrent leaf bases which run down the stem ridges, and the absence of a white band of hairs below the peristome. From N. reinwardtiana it is distinguished by the slender, gracile pitchers, the shortly-toothed peristome (vs. untoothed), the absence of eye-spots, the lid with its few, large nectar glands and the 1-flowered partial peduncles (vs. 2-flow-ered).
2. Blume cites Jack’s misapplication of the name N. distillatoria and Wallich’s Cat. No. 2244 under his variety elongata. The former is not possible to certainly identify, whilst the Wallich herbarium at K comprises at least 5 sheets with N. gracilis, and on two of these are attached specimens of N. albomarginata also. Five further sheets of this number comprise specimens of N. khasiana.
3. Nepenthes neglecta Macfarl. is discussed under ‘Excluded Species’ in relation to N. gracilis.
