Brief SummaryRead full entry
DescriptionNepenthes macrophylla is a beautiful carnivorous plant that grows only on the summit of a single mountain on the island of Borneo (2). A vine which grows to a length of about ten metres, Nepenthes macrophylla has modified pitcher-shaped leaves that hang from coiled tendrils into which insects and other invertebrates fall (2). The semi-woody pitchers of Nepenthes macrophylla are usually cylindrical, becoming narrower at the midpoint (4). The pitchers contain an acidic fluid, secreted by the many glands which cover the inside surface of the lower half of the pitcher (5). The smooth and waxy upper inner surface of the pitcher makes it impossible for insects that fall into the pitchers to gain a foothold (5), and a ridge of hardened tissue lining the mouth of the pitcher, the peristome, bears well developed, downward pointing teeth, also preventing insects from escaping (2). A lid overhangs the mouth of the pitcher, preventing rain water from diluting the pitcher fluid (2). The pitchers of Nepenthes macrophylla vary in colour, but in general the upper surface of the lid is red and the lower surface green, the peristome is dark red, the rest of the outer surface of the pitcher is also red and the inner surface is green. The inflorescences are a dull red-brown and green in colour and very short inconspicuous hairs cover the plant (2) (4).
