Fig

Based on five plants:

1. Rafflesia: ...
Scientific name: Rafflesia arnoldii
Location: Indonesia
About the Plant: Because of its stench, the Rafflesia is another "corpse flower." ... It's unique in that it is the world’s largest single flower. It is also wacky because it has no stems, leaves, or roots, though it does seem to be a plant of some kind. Some think it’s related to fungi. The Kew Botanical Gardens website puts it in class Equisetopsia (related to horsetails), but Wikipedia puts it in the class Malphigiales (a large category including willows and flaxes). ... [T]hese are extremely hard to find. They live most of their lives as inconspicuous strands of parasitic tissue on Tetrastigma vines in tropical rainforests, until the strands develop a little inconspicuous bud, which for a few brief days explosively transforms into the terrifying plant[.]

2. Cape Sundew
Scientific name: Drosera capensis
Location: South Africa
About the Plant: There are more carnivorous plants out there than you probably realized (more than I realized, anyway). The Cape sundew, native to South Africa, traps insects not with rapid movements or weird pitcher-shaped appendages, but by slowly wrapping its “arms” (its sticky, sap-covered leaves) around its prey. This process is slow (on the average it takes about 30 minutes) and is probably fairly cruel. ... It reseeds easily and can survive a wide range of temperatures. It is on New Zealand’s list of invasive plant pests.

3. Strangler Fig
Scientific name: Ficus (several tropical and subtropical species)
Location: Australia
About the Plant: ... There are many different species of strangler fig, but they all are basically the same thing: that roommate who steals all of your food[.] ... They are usually dispersed by hitch-hiking on birds and being dropped on the canopy of trees of a dense forest. They are wacky because they will grow up and down. They grow down so that their roots can rob the living tree of all its nutrients. It grows upwards to absorb sunlight. They often outlive the host tree by years.

4. African Acacia
Scientific name: Acacia (now Vachellia) species
Location: Africa, Serengeti
About the Plant: An acacia on a plain looks so innocent, (the classic image of the African savannah). I think I saw it on The Lion King. Well, the tree is a mass murderer. If an African Acacia tree is under attack by a grazing animal, say a kudu, it releases a cloud of ethylene gas, thus warning trees up to 50 yards downwind to produce extra tannin in their leaves, making them toxic. Besides using gas, toxins, and thorns to defend themselves, acacias often hire an army of ant bodyguards. The trees provide housing and nectar for the ant, and the biting ants attack whatever comes near the tree. The plant does need herbivores to help propagate it, however, so the ants can’t be too efficient in chasing away all grazers and pollinators. Thus acacias have some complicated three-way relationships.

5. Dragon's-Blood Tree
Scientific name: Dracaena cinnabari
Location: Africa
About the Plant: ... Its sap resembles dragons' blood. It’s a deep red, even when dried into resin. It was prized among the ancients. It can be used for stimulants, and for toothpaste, of all things. Luckily, it survived thousands of years of everyone trying to collect it, which is saying a lot since it is only found on the island of Socotra. The species is a remnant of a subtropical forest ecosystem that used to stretch across North Africa, until the desert took over there. The canopy looks like an umbrella and acts like one. It shades the roots and reduces evaporation. The trees tend to bunch together, because the shade collects what slight dampness there is on Socotra (which gets 10 inches of rain a year) and helps seedlings grow.
