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.

What are the differences between Nymphoides peltata, Nymphoides indica, and Nymphalis? We explain how to distinguish between similar species! Why are they endangered? Did Nymphoides peltata and Nymphoides indica survive through a strategy of pleasing everyone?

Nymphoides peltata, Nymphoides indica, and Nymphaea japonica are three species of floating-leaved plants with round leaves found in lakes and ponds in Japan. While they look very similar, Nymphoides peltata and Nymphoides indica belong to the Menyanthaceae family, while Nymphaea japonica belongs to the Nymphaeaceae family, making them completely different. 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...

What are the differences between Gentiana scabrida and Gentiana scabrida? We'll explain how to distinguish between similar species! Is it true that they have medicinal properties? Gentiana scabrida species change flower size and alter their pollination strategy depending on the environment!?

*Gentiana scabrida* and *Gentiana scabrida* are two species of plants native to Europe that bear pretty pink flowers, and they have become commonly seen in Japan in recent years. This has been the case since 1960. These two species can be distinguished by carefully observing their life forms, basal leaves, and corollas...

What are the differences between Plumbago auriculata and Plumbago prunifolia? We explain how to distinguish between similar species! Are there two types of stamen length? Only insects with long mouths can suck nectar from the flowers!?

Plumbago (Plumbago auriculata) and Plumbago rhododendron are two horticultural varieties of the Plumbaginaceae family that produce somewhat unusual blue flowers. In Japan, they are cultivated in gardens for ornamental purposes, and are easily confused due to their similar names, blue flowers, and similar flower shapes. However, their classification is based on their genus level...

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...

What are the differences between Lespedeza bicolor and Robinia pseudoacacia (black locust)? We'll explain how to distinguish between these similar species! Why are they considered invasive species of concern? The two species have contrasting flowers and fruits!

Black locust and black locust are both members of the legume family, have odd-pinnately compound leaves composed of numerous leaflets, and are often confused with each other because they are used for greening and naturalize in similar environments. In Japan, both are classified as invasive alien species (formerly designated as species requiring caution) due to their potential to cause damage to ecosystems. The difference between these two species is the presence or absence of thorns...

What are the differences between Trachelospermum asiaticum, Trachelospermum asiaticum, and Trachelospermum asiaticum? We'll explain how to distinguish between similar species! Is it historically true that the name originates from "Fujiwara no Teika"? What is the ecological reason why they bloom and emit a fragrance in the evening?

Trachelospermum asiaticum and Trachelospermum asiaticum are climbing plants that can be widely found in Japan, from forests to urban areas, including cultivated varieties. They can be distinguished by the hairs on the underside of their leaves and the length of their flower tubes. They have been widely known in Japan since the time of the writing of the Kojiki, and their current names are derived from "fuji" (wisteria)...

What are the differences between Salvia japonica, Salvia japonica, Salvia japonica, and Salvia japonica var. alpina? We'll explain how to distinguish between similar species! Did the flowers fit snugly onto the bees, leading to successful pollination?

Salvia japonica, Salvia japonica, Salvia japonica in autumn, and Salvia japonica in mountain are all members of the Salvia genus, known as wildflowers of Japan, but their similar names can sometimes lead to confusion. These similarly named Salvia species can be distinguished by carefully observing the structure of their corollas, stamens, and leaves...

What are the differences between Spiraea thunbergii and Prunus serrulata? We'll explain how to distinguish between similar species! Is the claim that they're related to Sen no Rikyu a myth? What role do the green parts of the flowers play?

Spiraea thunbergii and Prunus serrulata are native to China, and Spiraea thunbergii in particular is commonly cultivated in tea gardens and ordinary gardens in Japan. Prunus serrulata is also cultivated, though less frequently. These two species can be reliably distinguished by the serrations on their leaves, and they can also be distinguished by their flowers...
