Taxonomy
1 Nepenthes reinwardtiana is unusual in the ‘eye-spots’, which contrast strongly against the back of the glaucous inner pitcher wall. In some populations there may be pitchers with one, three or no eye-spots (). Similar spots have been reported, but only as single pitchers on odd plants, in N. sanguinea, N. stenophylla, and N. tentaculata ( ). Nepenthes reinwardtiana is sometimes confused with N. gracilis, with which it shares sharply triangular stems and decurrent, sessile leaf bases. Nepenthes reinwardtiana can be distinguished by its leaves with 1-3 (vs. 4-6) pairs of longitudinal nerves, by the inner peristome which lacks teeth and has instead a prominent row of glandular pits. Furthermore, N. reinwardtiana has the base of the lid truncate and not cordate, and bears numerous small nectar glands (those of N. gracilis are few and large) and the partial peduncles are 2-flowered (vs. 1-flowered). report that red pitchers seem to be found only on plants growing on ultrabasic, sandy heath or podsolic soils.
2. J.H. Adam & Wilcock base their variety samarindaiensis on specimens with rounded stems and non-decurrent leaf bases found in E Kalimantan. As indicated by , reports of this species in Peninsular Malaysia are based on the misidentification of specimens or misinterpretation of localities from collecting notes.
