Appearance

Unlike most ''Nepenthes'' species, ''N. deaniana'' does not climb. The stem is 20 to 30 cm tall, 4 to 5 cm wide, and glabrous throughout. Plants spread by means of shoots. Leaves are lanceolate or obovate in form, 6 to 12 cm long, and 3.5 to 4 cm wide. They possess 4 to 5 pairs of longitudinal veins, connected by irregularly reticulate transverse veins. Tendrils are 10 to 15 cm long.

Pitchers are obconic, 6 to 9 cm high, and 2.3 to 3.5 cm wide. The peristome is cylindrical and 5 to 8 mm wide, bearing long attenuate teeth on its inner margin. The operculum or lid of this species is broadly cordate.

The male inflorescence is 15 to 20 cm long and may be pubescent to glabrous.
Pedicels are 1-flowered, compressed and expanded at the base. Individual flowers have 4 sepals and 8 anthers.

The members of the Palawan Mountaineers who climbed Thumb Peak in 1993 actually took photos of ''N. deaniana'' and included it in their photo exhibit the same year, not knowing the identity of the plant.-->
