Description

As N. lowii but differing as follows: Leaves of climbing stems with petiole base de-current as two prominent, recurved ridges that unite above the node below. Longitudinal nerves entirely absent, rarely 1. Pennate nerves oblique, branching 1 or 2 times before reaching edge of leaf, conspicuous. Upper pitchers only very slightly constricted at midpoint; the peristome more pronounced; the lid relatively broader and larger than N. lowii, lower surface with numerous stout spike-like processes 2-3 by 1 mm towards the base, nectar glands volcano-like, 1 mm wide with a narrow central opening < 0.1 mm wide, these glands more numerous toward the lid margin, where the processes are absent.A

Notes

The drawing of N. ephippiata in Danser Bull. Jard. Bot. Buitenzorg III 9 (1928) 427, f. 36 is not accurate. In N. ephippiata the lid bristles are less numerous, more concentrated towards the base of the lid and are both shorter and stouter than those shown. Danser in Bull. Jard. Bot. Buitenzorg III 9 (1928) 426 seems not to have fully appreciated how similar this species was to N. lowii. Both N. ephippiata and N. lowii have more or less cylindrical lower pitchers with a well-developed peristome: it is only the upper pitchers that are so bizarrely formed. The saddle-like decurrent petiole-bases, from which N. ephippiata derived its name, are similar to those of some N. northiana collections.
Nepenthes ephippiata appears to replace N. lowii in the central mountains of Kalimantan, the latter being abundant in parts of Sarawak, Brunei and Sabah.A
