Distribution of N. gymnamphora. (incomplete)

Nepenthes gymnamphora (Greek: gymnos = naked, amphoreus = pitcher) is a species of pitcher plant endemic to Java. There is much confusion surrounding the status of this species and the closely related N. pectinata and N. xiphioides.

Morphological differences between N. gymnamphora* and N. xiphioides (Salmon & Maulder, 1995)
Morphological character N. gymnamphora N. xiphioides
Longitudinal leaf veins 3-6 running in outer 2/3- 4/5 of blade 2-3 running in outer 1/2 of blade
Leaf margins covered with short dense hair glabrous
Rosette leaf tendril about as long as the pitcher 2-3 times as long as the leaf
Rosette pitchers 8-12 cm tall, 3-4 cm broad 4-5.5 cm tall, 1.5-2 cm broad
Aerial pitchers present absent
Peristome teeth 3-6 times as long as broad 6-8 times as long as broad
Inflorescence mostly 2 flowered, upper most ones 1 flowered; rarely most or all of them 1 flowered 1 flowered but bearing some 2 flowered pedicels in lower 1/3
Staminal column hairy at base or over whole length glabrous

* Salmon & Maulder (1995) treat N. pectinata as conspecific with N. gymnamphora.
