Nepenthes izumiae is a climbing plant growing to a height of 8 m. The stem ranges in color from green to reddish.

Rosette and lower pitchers are typically ovate in the basal quarter to half of the pitcher cup, becoming cylindrical and sometimes slightly infundibular above. A conspicuous hip often delimits these two parts of the trap. Terrestrial pitchers may be quite large, reaching 30 cm in height by 6 cm in width. A pair of fringed wings (?6 mm wide) runs down the ventral surface of the trap, bearing filaments up to 12 mm long. The peristome is cylindrical at the front and becomes flattened and broader towards the sides and rear, measuring up to 3 cm in width. It bears ribs up to 2 mm high and spaced up to 2.5 mm apart. These ribs terminate in teeth (?8 mm long) on the inner margin of the peristome, the largest being located towards the top. There is often a gap of several millimetres separating the two lobes of the peristome directly below the lid. The pitcher lid or operculum is ovate to orbicular and typically has a cordate base as well as a frilled margin. It measures up to 6 cm in length by 4.5 cm in width. A triangular or hook-shaped basal crest (?1 cm long) is commonly present on the lower surface of the lid. An unbranched spur measuring up to 10 mm in length is inserted near the base of the lid. Lower pitchers typically have a very dark pigmentation, being purplish-black throughout. However, the indumentum covering the traps can give them an orange or brownish sheen. The peristome is generally purple, black, or dark brown, but may have lighter coloured teeth ranging from green, through yellow, to white. The inner surface of the pitcher may be light yellow, white, or light purple, and often bears purple speckles. The pitcher lid is often yellow or green on the underside and dark purple on its upper surface. Occasionally, the pitcher may be yellowish-green throughout with a black peristome.

Upper pitchers are narrowly infundibular in the basal third to half of the pitcher cup and cylindrical above. A constriction and associated hip often delimit these two parts. Aerial traps are smaller than their terrestrial counterparts, reaching 20 cm in height by 4 cm in width. In upper pitchers, the wings are reduced to ribs. The peristome, which reaches up to 8 mm in width, is cylindrical and expanded at the sides and rear. It bears ribs up to 0.5 mm high and spaced up to 0.5 mm apart as well as teeth up to 1.5 mm long. The pitcher lid is sub-orbicular to slightly ovate and has a cordate base. It measures up to 4.5 cm in length by 4 cm in width. It may or may not bear an appendage on its underside. The spur is simple[4] or branched[8] and attains a length of 5 mm. Upper pitchers exhibit a similar pigmentation to lower pitchers, but are typically lighter.

Nepenthes izumiae has a racemose inflorescence up to 18 cm long, of which the peduncle constitutes up to 10 cm and the rachis up to 8 cm. Flowers are borne solitarily on pedicels (?5 mm long) that lack bracts. Tepals are ovate and up to 6 mm long. Fruits reach 15 mm in length. The structure of the male inflorescence has not been documented.

An indumentum of red, brown or white hairs up to 1 mm long may be present on the laminar margins, pitchers (particularly lower ones), tendrils, and parts of the inflorescence

GERMINATION

These seeds germinate best on dampened sphagnum moss. Soak the moss for 1 hour, then gently squeeze out excess water, but allow some moisture to remain (not dripping). Place the moss in a container, and sprinkle the seeds on top. Cover the container with plastic to retain moisture. Place the container in very bright light, and in a very warm location, ideally 32C, 90F. Once the small plants begin to grow, slowly open the plastic a little each day. Use rain water or bottled water (use a spritz bottle while plants are small) to regularly water plants, but do not leave them standing on water. Once plants are large enough to transplant, a growing mix consisting of equal parts peat moss, perlite, vermiculite and sphagnum moss (long fibre type) can be used. Seeds germinate anywhere from 1 month, to 12 months. Patience is needed, but they are worth the effort for this unique plant
