 Possible new species

  1. Nepenthes tenuidon Suarez & Ferreras, ined. LUZON: Zambales. In ultramafic substrates at ca.1600 m altitude.
  2. Nepenthes sp. 1 (Cetaceo) - Insignes group. Pitcher green with irregularly shaped red spots; trichomes on pitcher wings branched into two or three; peristome teeth relatively large, including those on the column.
  3. Nepenthes sp. 2 (Mingan) – Insignes group. Lower pitchers variably red, similar to N. sibuyanensis, but upper pitchers more elongated, green with faint reddish blotches; peristome slightly flaring, green with reddish-orange ribs; operculum smaller than the diameter of the mouth. May be a disjunct population of N. sibuyanensis.
  4. Nepenthes sp. 3 (Zambales) - Regiae group. Stem four-cornered, stiff and woody, non-sprawling; axillary buds prominent; pitchers with indumentum, green, suffused with orange and with red-orange streaks.
  5. Nepenthes sp. 4 (Zambales) – Regiae group. Pitchers green throughout, superficially similar to N. alata especially by the presence of a basal lid appendage, but operculum more orbicular with a cordate base and rounded apex and possessing no median keel as in N. alata; pitcher base infundibular in front, not ventricose.
  6. Nepenthes cf. alata (Bicobian) – Pitchers similar to N. alata but relatively stouter, operculum glands large, loosely scattered.
  7. Nepenthes cf. alata (Mingan) – In all respects similar to N. alata, but fringe elements denser and much longer (reminiscent to those on the lower pitchers of N. fusca), upper surface of the operculum base with sparse multicellular hairs similar to that seen in N. tentaculata and related species. Compared to N. alata, the peristome ribs are higher and somewhat more separated and terminating in filiform teeth, characters not seen in any known variation of the said species.
  8. Nepenthes cf. boschiana MINDANAO: Davao Oriental (Mt Hamiguitan) Shape of operculum, distribution of the dimorphic glands (smaller glands widely scattered, larger ones concentrated on or around the barely developed median keel), the undulating peristome and the general shape and colouration of the pitchers very similar to N. boschiana, but fringe elements sparser and shorter. Another specimen but with green pitchers and red-striped green peristome is also very similar with regards to the shape and morphology of the operculum and the distribution of glands, but the pitchers are hipped and in this respect approaches N. faizaliana, itself closely related to N. boschiana.
  9. Nepenthes ampullaria Jack, Comp. Bot. Mag. (1835) 271; --Type from Singapore. Thailand, Sumatra, Peninsular Malaysia, Borneo, Philippines, New Guinea. Known in the Philippines only from a single plant collected from an undetermined locality. More specimens are needed to determine its exact distribution within the country. Photos
  10. Nepenthes maxima Reinw. ex Nees, Ann. Sci. Nat. 3 (1824) 369, t. 20, Fig. 2; --Type: ? Reinwardt 1537 (L), Sulawesi: Manado, Gunung Rumengan, 1821. Sulawesi, the Moluccas, Philippines, New Guinea. MINDANAO: Davao Oriental (Mt Hamiguitan). Epiphytic in mossy forests, but also as terrestrials in swampy grasslands, on ridge tops, open podzolic forests, rocky substrates and ultramafic soils at elevations from 600-2500 m.
