Nepenthes Attenboroughii - Description - Leaves and Pitchers

Leaves and Pitchers

The leaves are coriaceous and sessile or sub-petiolate. The leaves of rosettes are up to 30 cm long and 10 cm wide, whereas those of the scrambling stem are up to 40 cm long and 15 cm wide. The leaves are oblong to elliptic, obtuse at the apex and shortly attenuate at the base, clasping the stem by approximately two-thirds of its circumference and becoming decurrent for 2–3 cm.

Nepenthes attenboroughii produces some of the largest pitchers in the genus, sometimes exceeding those of typical N. rajah in size, but is not known to have exceeded the size and volume records set by that species. The largest recorded pitcher of N. attenboroughii measured more than 1.5 litres in volume, and traps exceeding 2 litres are likely to be produced on occasion. The lower pitchers are brittle and campanulate (bell-shaped), up to 30 cm tall and 16 cm wide and emerge from tendrils that are 30–40 cm long and 4–9 mm in diameter. The tendrils are flattened towards the leaf, making them almost semi-circular in cross section.

The upper pitchers are similar to the lower pitchers, but generally infundibular, to 25 cm tall and 12 cm wide.

Famous quotes containing the words leaves and, leaves and/or pitchers:

    What is a country without rabbits and partridges? They are among the most simple and indigenous animal products; ancient and venerable families known to antiquity as to modern times; of the very hue and substance of Nature, nearest allied to leaves and to the ground,—and to one another; it is either winged or it is legged. It is hardly as if you had seen a wild creature when a rabbit or a partridge bursts away, only a natural one, as much to be expected as rustling leaves.
    Henry David Thoreau (1817–1862)

    he went down
    As when a lordly cedar, green with boughs,
    Goes down with a great shout upon the hills,
    And leaves a lonesome place against the sky.
    Edwin Markham (1852–1940)

    Little pitchers have big ears.
    Unknown (20th century)
