Climbing stem internodes 3–4 cm; leaves green, 19 cm × ca. 3.5 cm, linear-lanceolate, sessile, 3–4 veins on each side run parallel to the midvein, pennate veins arising from the midvein at 45–80° angle, leaf base clasping up to ½ of the stem diameter becoming decurrent up to the entire internode, apex acute. Ground pitchers ellipsoidal to urceolate, up to 22 cm long × 14 cm at widest region; wings up to 1.5 cm with filaments up to 1.5 cm long run the entire pitcher anterior; pitcher exterior yellow green suffused and blotched with blood red subtended by uncoiled yellow-green glabrous tendrils ca. 43 cm long and 1.5 cm in diameter; pitcher interior yellow-green blotched with dark red; peristome ovate slightly tapering posteriorly giving a short neck, color variable from yellow-green suffused with red to entirely dark red; lid ovate, ca. 8 × 6 cm, dorsal and ventral surface with variable coloration from entirely olive green to suffused red. Aerial pitchers wholly infundibular, slightly inflated bottom ½, 19.5 cm long x up to ca. 6 cm at the widest region, subtended by coiled tendrils; pitcher exterior suffused red, pitcher interior waxy zone yellow-green blotched with dark red, digestive zone dark green; peristome ovate slightly tapers posteriorly giving a short neck, variable coloration from yellow-green suffused with blood red to entirely dark red, teeth triangular ca. 1 mm, with ridges elevated ca. 0.1 mm with ca. 1 mm space in between; lid ovate, up to ca. 8 × ca. 6 cm, dorsal surface with distinct paired elevated vein with short indumenta running up to half of the lid, up to 4 veins arise from base of the paired veins running the entire lid, up to 3 veins traverse the lid shallow depressed mid-region; lid ventral surface with small extrafloral nectar glands (ca. 0.1 mm) evenly distributed, central basal appendage or ridge absent; lid spur filiform, unbranched, up to 13 × 1 mm tapering to the slightly biforked. Female Inflorescence glabrous, 2-flowered partial peduncles sit on a ridge giving the rachis an angular appearance, rachis ca. 30 cm long, scape ca. 11.5 cm, ca. 7 mm in diameter; partial peduncles ca. 7 mm long, 2 mm in diameter; pedicels subtending the florets ca. 1 cm long, 1 mm in diameter; fruits ca. 1.3–2.5 cm; tetrapetalous, tepals narrow-ovate, 5 × 2 mm; seeds many, length ca. 1.5 cm x 1 mm. Male Inflorescence 2 flowered partial peduncles sit on a 35 cm long rachis, scape, yellow-green, ca. 11 cm long; partial peduncles sit on a ridge giving the rachis an angular appearance, 2 mm long, ca. 1 mm in diameter, with filiform process ca. 0.5 cm long arising near the base; pedicels subtending the florets, yellow-green to yellow to brownish, ca. 1 cm; tepals ovate-lanceolate, ca. 5 mm x 3 mm, concave, floral nectar glands ovate to narrow-ovate, ca. 0.8 × 0.1 mm, yellow-green suffused with red towards the margins; anther tubes ca. 3 mm long, 1 mm in diameter, suffused with pinkish red; florets faint yellow, 2 mm x 3 mm, theca ca. 20 centrally fixed recurved forming a head.</p><p>Taxonomic and ecological notes: —  Nepenthes surigaoensis belongs to  Nepenthes sect. Insignes or  N. ventricosa Blanco (Blanco 1837: 807) as characterized characterized by its lack of petiole, broadly subcylindrical pitchers with broad peristome which is conspicuously toothed on its inner surface. It is easily mistaken for  N. merrillian a due to striking similarities but can be delineated in having strongly decurrent leaf-to-stem attachment ( N. merrilliana: obliquely decurrent up to 2/3 rd of the stem internode), subcylindrical aerial pitchers (vs. wholly infundibular). It thrives on gravel and clay-loam substrates at 700–1100 m asl in Talangisog, Eureka, Gingoog City, Misamis Oriental; Mt. Pantaron Range (Fig. 3), Mt. Limbawon, Tago Range (Fig. 4), Mt. Kiamo, in Bukidnon. Other noteworthy species thriving with  N. surigaoensis includes  N. cabanae Lagunday &amp; Amoroso (2019: 39),  N. manobo Lagunday, Acma, Cabana, Sabas &amp; Amoroso (2017: 161),  N. malimumuensis Lagunday, Acma, Cabana, Sabas &amp; Amoroso (2017: 161),  N. talaandig Gronemeyer, Coritico, Wistuba, Micheler, Marwinski, Gieray &amp; Amoroso (2014: 292), and  N. truncata Macfarlane.
