The following description is based upon the text and illustration presented in Macfarlane (1908).
The lamina is elliptic or lanceolate, up to 40 cm long and 9 cm wide. The apex of the leaf is obtuse or rounded, and the base is attenuate and petiolate. The petiole is up to 10 cm long, winged, and amplexicaul, clasping up to half of the stem. Most parts of the plant are covered with dark, reddish brown hairs.
The lower pitchers are up to 18 cm tall and 5 cm wide. The bottom half of the trap is swollen, narrowing above this part and becoming cylindrical towards the pitcher opening. Broad wings run down the front of the pitcher and are fringed with long, narrow filaments. The pitcher opening is oblique and ovate, rising at the rear to form a short, elongated neck. The peristome is broad, up to 10-15 mm wide, recurved along the outer margin, and lined with distinct ribs that form a rim of short teeth on the inner margin. The lid is up to 7 cm long and 5 cm wide, and is ovate with a cordate base, and has numerous glands on its lower surface that are large towards the middle and smaller towards the edges. The spur is unbranched and up to 15 mm long, with a club-shaped tip.
The upper pitchers are up to 30 cm tall, 6 cm wide, and cylindrical. The wings are partly reduced to irregular fringes or entirely to narrow ridges. The peristome is oblique and narrower than in the lower pitchers. The lid and spur are similar to those of the lower pitchers.
The colour of the leaves and pitchers is not known, although the depiction presented by Macfarlane (1908) indicates that colouration may include interior mottling of upper and lower pitchers. The structure of the inflorescence and fruit is not known.A


Danser (1928) reduced this species to a synonym of N. mirabilis, but noted that he did not examine the type. Jebb & Cheek (1997) [and Cheek & Jebb 2001 - Berendsohn (2017+)] did not examine the type either and followed Danser's interpretation. Recent observation of the type by Schlauer & Nepi (2000) suggested that N. beccariana is related to N. sumatrana and N. longifolia, and has little in common with N. mirabilis.B
