What are the differences between Chinese tallow tree and Japanese wax tree? We explain how to distinguish between similar species! Why did the white seeds, which contain a lot of fat, evolve?

Both the Chinese tallow tree (Toxicodendron sylvaticum) and the Japanese wax tree (Toxicodendron succedaneum) are deciduous trees, and both share the name "haze." This name comes from the fact that their fruits or seeds contain a large amount of fat, which has historically been used as wax. However, perhaps because of this, the Chinese tallow tree and the Japanese wax tree are often confused...

What are the differences between Pyrus pyrifolia, Ailanthus altissima, and Lucifer praecox? An explanation of how to distinguish between similar species.

Both *Pachypodium sibiricum* and *Ailanthus altissima* belong to the Simaroubaceae family and are deciduous trees sometimes planted in Japan. *Ailanthus altissima*, in particular, is known for its rapid growth and widespread naturalization worldwide. However, they share similarities, such as having odd-pinnately compound leaves, so those unfamiliar with them might not distinguish them...

What's the difference between loquat (Biwa) and wild fig (Inubiwa)? How do they differ from apricots, persimmons, and mangoes? We'll explain how to distinguish between similar species! Insects and small birds visit loquat blossoms that bloom in winter!?

The loquat (Ficus microcarpa) is an evergreen tree native to China, cultivated worldwide for its edible fruit. In Japan, it is frequently cultivated not only for food but also for ornamental purposes. A similar-sounding species, the deciduous shrub known as *Ficus erecta*, is often confused with the loquat due to its oval-shaped, fruit-like structure...

What are the differences between Kibushi and Hachijo-kibushi? What are the different species in the Kibushi genus? We'll explain how to distinguish between similar species! Do the fruits turn your teeth black? Did the flowers have a strategy to attract different insects during the day and night?

Stachyurus praecox, once considered endemic to Japan, is now widely distributed throughout the country. Although there are only two distinct species, their varieties are quite diverse, making identification difficult. While some argue that these variations exhibit continuity and should not be distinguished, this article will deliberately avoid making distinctions...

What are the differences between Japanese wax tree (Rhus sylvestris), Japanese lacquer tree (Rhus trichocarpa), and Japanese lacquer tree (Rhus trichocarpa)? We explain how to distinguish between similar species! Why do they cause rashes? Why was Japanese lacquer tree used as a raw material for Japanese candles? What birds in nature like them? Did autumn foliage play a role?

Japanese wax tree (Rhus sylvestris), Japanese lacquer tree (Rhus trichocarpa), and Japanese lacquer tree (Rhus trichocarpa) all belong to the Rhus genus and are relatively common even in urban areas. They are similar species often seen in gardens and along roadsides, characterized by their odd-pinnately compound leaves. Distinguishing between them is difficult, but careful observation of the leaves is essential. The number of leaflets and the degree of hairiness are major clues...
