Taxonomy
2. This species was synonymised with N. gracillima Ridl. by Danser, but we reinstated it in 1997 (). The illustration of N. gracillima in is of N. ramispina. From the other Peninsular Malaysian species it can be distinguished by its cylindrical, pubescent stems, slender pitchers and branched spur. See key under N. gracillima.
1 Nepenthes ramispina is closely similar to N. gracillima. It can be diagnosed by its larger habit, broader, oblong-obovate leaves, the more slender and longer upper pitchers with long, fasciculated spurs (vs. simple and < 3 mm), the glands on the underside of the lid which are numerous, unbordered, and range from 0.1 mm near the margin to 0.4 mm wide near the middle (vs. lipped and evenly sized from 0.4-0.6 mm), and the pubescent stem and midrib (vs. glabrous to sparsely pubescent).
