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...

Trachelospermum Jasminoides Var Pubescens Hatsuyukikazura Flower

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's the difference between crape myrtle and striped crape myrtle? We explain how to distinguish between similar species! Did you know that flowers use false pollen as bait to successfully pollinate?! An amazing tactic to deceive bees! Seed dispersal isn't just by wind?!

Both crape myrtle (Lagerstroemia indica) and Japanese crape myrtle (Lagerstroemia indica) are commonly planted in Japan and can be seen in many places, even in urban areas. While their smooth bark makes them easy to distinguish from other species, the two species are so similar in morphology that they are often confused...

What are the differences between Bupleurum falcatum and Bupleurum chinense? We'll explain how to distinguish between similar species! Why are they used in traditional Chinese medicine? Why are they endangered? Do flies come to the flowers to lick the nectar?

Bupleurum falcatum and Bupleurum chinense are both yellow-flowered plants belonging to the Apiaceae family that grow in sunny grasslands, so it can be difficult to distinguish between them. The difference lies in whether the base of the stem leaves clasps the stem or not. While it may not be possible to distinguish them by the shape of the flowers, there are differences in the shape of the involucral bracts...

What are the differences between trumpet vine and American trumpet vine? What are the differences between it and bellflower? We'll explain how to distinguish between similar species! Is it really non-toxic and actually poisonous?! Did they follow separate evolutionary paths in the Old World and the New World?!

The trumpet vine (Campsis grandiflora), American trumpet vine (Campsis radicans), and bellflower (Campsis lanceolata) are three species of climbing horticultural plants native to North America, commonly used as garden trees and for landscaping. Distinguishing between them is easy if they are flowering; if that's not possible, you'll need to examine the underside of the leaves closely, although the differences are minimal...

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...

Adenophora Triphylla Var Japonica Flower

What are the differences between Adenophora triphylla, Adenophora fukushimaensis, and Campanula punctata? We explain how to distinguish between similar species! Did the blue flowers only produce nectar at night?! An unexpected adaptation that belies their appearance.

Adenophora triphylla, Adenophora fukushimaensis, and Campanula punctata are representative Japanese herbaceous plants that grow in forest edges and other areas, bearing numerous purple flowers. All belong to the Campanulaceae family, genus Adenophora, and are similar in that they grow in forests and bear downward-facing purple flowers, which can sometimes make them difficult to distinguish. However...

What are the differences between Syzygium rufinerve, Syzygium rufinerve (Javan syrup), and Syzygium rufinerve? We'll explain how to distinguish between similar species! Do birds visit the bushy flowers? And can they even form fruit without pollination?!

Myrtus communis, also known as rose apple or adek, is a plant belonging to the Myrtaceae family, genus Myrtus, and is well-known for its entire leaves and edible fruit. While you might see it in botanical gardens or in Okinawa, it's a tropical plant, so it's rarely seen in mainland Japan, and many people don't know how to distinguish it from other plants...

What are the differences between Mitsumata and Ganpi? We'll explain how to distinguish between these similar species! Why is Mitsumata used as the raw material for Japanese banknotes? Do flowers require insects with long mouths to thrive?

Both Mitsumata and Ganpi belong to the Thymelaeaceae family and are used to make washi (Japanese paper). Their flowers are quite similar in shape. However, despite being in the same family, Mitsumata and Ganpi belong to different genera, and a closer examination of their flowering periods and inflorescence shapes reveals various differences. Ganpi was the first to be used for washi...

What are the differences between Erythrina variegata, Erythrina crista-galli (American Erythrina), and Coral Tree? We explain how to distinguish between similar species! Is it an invasive species in Okinawa? Why is it Okinawa's prefectural flower? Did the Erythrina genus evolve its pollination strategy using hummingbirds in the New World?

The three species of Erythrina variegata (Deigo), Erythrina variegata (American Erythrina), and Coral Tree (Erythrina crista-galli) are relatively common in Japan and are cultivated for ornamental purposes. They are sometimes confused with each other because they have red flowers and trifoliate compound leaves. While the leaves are very similar, careful observation of the leaflet shape, thorns, and petioles is important...
