appendages on its lower surface. A flattened spur measuring up to 5 mm in length is inserted near the base of the lid. It may or may not be branched. Lower pitchers are typically light yellow to olive green and speckled with red or purple. The inner surface is a light shade of yellow. The peristome is generally yellow or orange in freshly opened traps, later becoming dark red to purple as the pitcher matures. The upper surface of the lid is often yellow with orange to purple blotches, whereas the underside may be completely red, although this is not always the case. Upper pitchers are either narrowly infundibular in the basal half of the pitcher cup and swollen above or infundibular throughout. A constriction is present just below the peristome. Aerial traps reach 12 cm in height by 6 cm in width. In upper pitchers, the wings may be partially developed near the pitcher mouth, or they may be reduced to ribs. The peristome reaches up to 24 mm in width and is similarly incurved to that found in terrestrial traps. Other parts of upper pitchers are similar to their lower counterparts. Upper pitchers exhibit a similar pigmentation to lower pitchers, but are typically lighter. Nepenthes talangensis has a racemose inflorescence up to 14 cm long, of which the peduncle constitutes up to 5 cm and the rachis up to 9 cm. The peduncle has a basal diameter of 2 mm. Flowers are borne solitarily on pedicels (≤10 mm long) with simple bracts. Tepals are elliptic and up to 4 mm long. Female and male inflorescences have a similar structure. A sparse but persistent indumentum of simple, white hairs is present on most parts of the plant. The density of hairs on the pitchers may be so low that they appear glabrous. The laminar margins are lined with red, brown or white hairs measuring up to 3 mm. Nepenthes talangensis varies little across its restricted range and has no infraspecific taxa. Ecology Nepenthes talangensis is thought to be endemic to the area around Mount Talang in the Indonesian province of West Sumatra; it has been recorded from Mount Talang itself and from nearby Bukit Gombak. A population of apparently tetraploid plants is known. Although Nerz and Wistuba wrote in their formal description that N. talangensis is restricted to elevations above 2200 m, the species is now known to have
