Nepenthes inermis
Nepenthes inermis
Nepenthes inermis is a carnivorous plant in the genus of pitcher plants ( Nepenthes ). It is found only on Sumatra and is only poorly understood.
Description
Nepenthes inermis is a perennial, evergreen, climbing plant. The stems are 3-5 mm thick, irregularly shaped and triangular in cross-section at an obtuse angle.
The lanceolate - spatulate, acute or obtuse, for the accretion wedge-shaped tapering leaves of the climbing shoots are thin, leathery and sessile, 5 to 12 centimeters long and 1 to 1.5 inches wide. The sheet approach includes the stem to a third to a half. The Blattaderung is irregular reticulate. Most spring on each side three longitudinal veins from the leaf approach, which run parallel to each other in the outer half of the leaf blade. The tendrils are as long to twice as long as the leaf blade, a loop may be present.
About the floor cans, little is known. According to observations in nature they are very small and their peristome is similar to that of Nepenthes lowii. A Aufsammlung but has so far not taken place.
The green air cans are 5-9 inches high, tubular to slightly trumpet-shaped in the lower part, a trumpet shape at the top. Wing missing, the ribs are inconspicuous. The slightly laterally compressed pot opening measures up to 5 inches in diameter. A peristome is almost completely absent and is pronounced only as a weak ring of approximately 0.2 millimeters wide. The inner surface is covered almost entirely with each square centimeter 600 to 900 tiny, slightly bulging glands, causing the can outside light " hammer suddenly " acts. The red - brown spotted lid is very narrow wedge-shaped, up to 5 inches long and below the rounded tip 0.3 to 0.4 inches wide. The base contains many glands, near the midrib these are oblong - round, towards the edge around. The spur is 3 to 4 mm long, unbranched and is close to the cover.
The male inflorescences are wedge-shaped grapes. The inflorescence is 5 centimeters, the inflorescence axis 12 inches long, at the base it has a diameter of 1.5 millimeters. The flower stalks are flowered, bottom and in the middle of the 8 mm long, at the top they are shorter, the highest measure around 4 millimeters. The lower flower stalks above the insertion point to small, thread-like bracts. The bloom are oblong - round to lanceolate, tapering to a point and about 3 mm long and 1 mm wide. The stamens are inclusive of dustbag up to 4 millimeters long.
The female inflorescences similar to the male, but are somewhat shorter, flowering stem and flower stalks are about 3 inches long. The densely hairy ovary is sessile. The fruit is the approach less tapered than the tip.
Dissemination
Nepenthes inermis grows exclusively in Sumatra at altitudes 2300-2590 meters in mossy forests.
Ecology
As one of the few known species of the genus Nepenthes inermis grows epiphytic. Hopkins, Maulder and Salmon sighted copies heaped high in trees.
Cans strongly scented sweet and aromatic, the percentage of prey from the group of Diptera is compared to other kinds of Sumatra relatively high. The digestion fluid contained in the pitchers is extremely viscous, so that it can draw extremely long threads. Experiments in culture have proven that no rain water accumulate due to the shape of the cans and the very viscous liquid in the cans and catch the prey can wash out.
System
Nepenthes inermis was first described in 1928 by the naturalist Benedictus Hubertus Danser, the specific epithet is the Latin word in - Armus borrowed ( German for " unarmed ", " unarmed ").
