Family: Nepenthes

I doubt that Nepenthes is a vine with a stem vein length of three meters and a diameter of three or four mm, the shape is conical or nearly prismatic. The length between the nodules is about ten centimeters. Doubt Nepenthes leaves have no petioles and are leathery. The leaves are lanceolate to spoon-shaped, ten centimeters long and two centimeters wide. The front end is relatively sharp, the root is gradually narrow and long, and there are about 3 longitudinal veins on each side of the midrib, originating from the base third of the midrib. Pinnate veins oblique, irregular, but inconspicuous. The vines can be up to 15 cm long, and vine circles may appear. The lower pitchers of the doubtful Nepenthes rarely appear. Its base two-thirds are narrowly funnel-shaped, the upper part is oval, and the middle part shrinks into a cage shoulder. The lower cages are all smaller in size, up to 5 cm in height and 3.5 cm in width. The ventral third has a pair of cage wings, not wider than 3 mm.

2. Habits of Nepenthes Doubt

Nepenthes Doubt, like N. inermis, which is closely related to it, will Produces extremely viscous digestive juices. This allows N. thornless pitchers to capture prey in cage-like traps and stick to passing flying insects with the extremely sticky inner wall of the pitcher. Nepenthes domus has a similar method of capturing prey. For a long time, it was believed that N. doubtful was only distributed in Mount Talakmau, but a second native place of N. doubtful has been found, about 1600m above sea level. Nepenthes Doubtica is distributed at 1800~2700m above sea level in Trema Mountain. In the lower elevations of Mount Terema, Nepenthes domus doubts grows as an epiphyte in mountain forests. But when the altitude is above 2400m, the vegetation has become very short, so the doubtful Nepenthes there often takes root in the moss on the ground.

3. Planting of Nepenthes Doubt.

Nepenthes Doubtica also needs more nutrients. In the wild, she mainly relies on catching insects to provide the nutrients it needs. However, during artificial planting, there are often not many insects that can be caught, and additional nutrients are required. Generally, the method of fertilization is used. During the growing season, use general compound fertilizers diluted four thousand times to spray the foliage or pour it into 1/3 of the height of the cage, 1-2 times a month. It is not recommended to spray too much high nitrogen fertilizer on the foliar surface, which often results in very large leaves and small cages. I wonder if Nepenthes likes brightly lit places. Whether it can bask in the sun depends on the variety, and it is necessary to coordinate the relationship between light, temperature and humidity (when planting in a closed environment, it is necessary to prevent direct sunlight. high temperature). Appropriate light can make the color of the cage more vivid, but under the direct sunlight in summer, it must be shaded, otherwise the leaves are easily burned, which directly affects the development of the cage.
