Nepenthes Faizaliana - Description

Description

The climbing stem of Nepenthes faizaliana may be up to 8 mm in diameter. Internodes are cylindrical in cross section and up to 3 cm long.

The leaves alternate around the stem. They are petiolate and coriaceous in texture. The lamina is lanceolate to elliptic in shape and up to 14 cm long by 4 cm wide. Its has an acute apex and an obtuse base. The petiole is canaliculate and up to 5 cm long. It is semi-amplexicaul, but lacks wings. Two longitudinal veins are present on either side of the midrib. Pinnate veins are indistinct. Tendrils reach 20 cm in length.

Lower pitchers have not been formally described, although they are smaller and less frequently produced than their aerial counterparts. Upper pitchers are narrowly infundibular, becoming slightly wider in the upper part. They reach over 30 cm in height. In aerial pitchers, wings are usually reduced to a pair of ribs. The waxy zone of the inner surface is well developed. The pitcher mouth has an oblique insertion. The peristome is flattened, cylindrical in cross section, and up to 4 mm wide. The lid or operculum is orbicular and has a distinctive glandular crest on its underside. An unbranched spur is inserted near the base of the lid.

Nepenthes faizaliana has a racemose inflorescence. The female inflorescence of this species has not been formally described. In male inflorescences, the peduncle is up to 17 cm long, while the axis reaches 40 cm in length. Pedicels are one-flowered, up to 20 mm long, and typically possess bracts. Sepals are lanceolate to oblong in shape and up to 4 mm long. A study of 120 pollen samples taken from the type specimen (S 44163 (Lai & Jugah)) found the mean pollen diameter to be 32.3 μm (SE = 0.4; CV = 7.6%).

Nepenthes faizaliana bears an indumentum of white, stellate hairs on its stem and petioles. The upper surface of the lamina is glabrous, whereas the underside has a sparse covering of short, branched hairs. In addition, long white hairs are present at the base of the midrib.

Famous quotes containing the word description:

    An intentional object is given by a word or a phrase which gives a description under which.
    Gertrude Elizabeth Margaret Anscombe (b. 1919)

    Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.
    Elaine Heffner (20th century)

    Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.
    Willard Van Orman Quine (b. 1908)
