Where is the best spot to observe NEPENTHES in Madagascar ?

In Madagascar, it is located in 3 places: Taolagnaro (Fort-Dauphin), the Presqu’ile de Masoala and all along the Canal des Pangalanes.

Scientific or botanical name of NEPENTHES : Nepenthesenthes madagascariensis, Nepenthesenthes ventrata or ventricosa.

Among Westerners, Etienne de Flacourt was the first to describe it in 1658. The scientific community of the time was surprised to find it so far from its main home, that is to say in Southeast Asia. This botanist was therefore the first to mention his establishment in the Big Island.

For scholars, he was the first to state the "endemic pitcher plant" Nepenthesenthes madagascariensis, simultaneously with the "Madagascar Periwinkle". Source : Wikipedia.

The plant has been the subject of numerous observations and studies to date.

Vernacular names of NEPENTHES

The "natives" had known NEPENTHES for a long time. It fits into the pharmacopoeia used on the East Coast of Madagascar. It is thus attributed the following names : Amponga, Ampongandrano, Ampozandrano, Betakotra, Oramitako, Ponga, Ravinkapoaka, Takotra, Nepenthesenthes Masoalensis, Tsiveravera.

The vernacular names always indicate the location of the plant or its pharmacopoeia virtues. By stating the native name, one can quickly know the diseases that it could cure. This encyclical know-how was lost with the arrival of Western botanists, who took pleasure in naming plants with Latin names.

NEPENTHES is part of the red list of species to be protected according to The International Union for Conservation of Nature

What are the 2 fascinating peculiarities of this wicked carnivorous plant ?

The NEPENTHES would have medicinal virtues according to scientific sources.
Secondly: to keep it simple. Here is the extraordinary ingenuity of NEPENTHES. It is a carnivorous plant. It has developed an ingenious technick to capture its victims and ingest them, digest them. It produces in the walls of its "cup" in the shape of a jug or purse, a chemical product, sticky. This substance mimics the composition of the "pheromones" of female insects. And so. Once again, the males are attracted by this smell, conducive to meeting their females to copulate. This odor is considered "foul" to the human sense of smell.
This trap is said to be passive. The victims are captured without the trap being otherwise active. Botanical observers add that the trap is shaped like a leaf connected by a tendril to a leaf, shaped like an urn. It is particularly attractive with bright colors and its nectar, called "peristome". The victim insects, thus captured, are hooked and will slide slowly to the bottom of the urn. The latter is filled with digestive fluid.
To reproduce, NEPENTHES produces a flowering on the basis of a cluster adorned with many small, red flowers. Regarding the seeds, the plant is said to be dioecious : it is either female or male. Male flowers have a yellow tip, which does not exist in the female gender.

The pharmacology of NEPENTHES or ethnopharmacology

During a certain colonial era and in order to promote medicines of Western origin, scientists and doctors of the time (including those trained in medical schools in Madagascar) denigrated the indigenous pharmacopoeia.
