What's the difference between a banyan tree and a fig tree? Why is it called the "strangler fig"? Where are the flowers? Only one type of insect visits the flowers!? Where are the real fruits? It's an important food source for bats!?

The Japanese banyan tree (Ficus microcarpa) and the Japanese Ficus microcarpa (Ficus sylvestris) are known as two "strangler figs" in southern Japan, both producing drooping aerial roots and forming receptacles. Ecologically, they are similar, and it can be difficult to distinguish between them. However, there are significant differences in leaf venation and leaf length between the two.

There are differences between Phalaenopsis orchids and other similar species! We'll explain how to distinguish between them! Why are they so popular? What's their history? Did the flowers attach pollen clumps to the backs of insects?! But the species is unknown?

Phalaenopsis orchids are very popular in Japan as high-end potted plants and cut flowers. They are the number one orchid species in terms of both production volume and value. However, they are also known as "Phalaenopsis," which can be confusing. Biologically, however, the terms refer to different species, with Phalaenopsis being the "Phalae..." orchid.

They can be reliably distinguished by their flowers, but even just looking at the leaves can be quite telling...

What are the differences between Ternstroemia gymnanthera, Pittosporum tobira, Rhaphiolepis indica, and Ilex crenata? We explain how to distinguish between similar species! Did you know that Ternstroemia gymnanthera is a rare species in the biological world, possessing both male and hermaphroditic flowers on separate plants? And that its fruit deceives birds?

Ternstroemia gymnanthera is an evergreen tree that grows in relatively dry areas near the coast and is quite popular as a garden tree. However, because its leaves are entire and have no serrations, it lacks distinctive features and is often confused with completely different species such as Pittosporum tobira, Rhaphiolepis indica, and Ilex crenata. However, in many cases, the color of the leaf stalks...
