Tricyrtis - Crossbreed of Japanese and Taiwanese Ones? 杜鵑草 - 日本と台湾のハーフ？

英語の後に日本語が続きます。

Are they Japanese or Taiwanese? That is the question. My answer is that they're a hybrid of Tricyrtis hirta (commonly known as Japanese toad lilies) and Tricyrtis formosana (Taiwanese toad lilies).

The biggest difference between the two is that Japanese toad lilies have flowers only in the leaf axils, whereas Taiwanese toad lilies produce flowers at the tips of their branching stems. The toad lilies in the first three photos have flowers both at the top and along the axils, which makes me wonder if they are a Japanese-Taiwanese hybrid...

The plant is called a toad lily because its spots look like a toad's skin, which is quite different from how people in Japan see it. There, they are called hototogisu (lesser cuckoo) because the spots resemble the chest plumage of that small bird.

日本と台湾の杜鵑草（ホトトギス）の交配種です（だと思います｡｡｡）。最初は台湾ホトトギスかと思ったのですがなんか違うな、と思って写真撮って確認したらやっぱ違う！花が茎の先だけじゃなくて茎の間（葉腋）にも咲いている。えっ？ということは日台ハーフ😉？

台湾ホトトギスと日本の特産種のホトトギスは花の咲き方が違います。台湾ホトトギスは茎が枝分かれしてその先に花が咲くのに対し、日本特産は葉腋（葉の付け根部分）に花が咲きます。

ホトトギスの名の由来は、斑点が鳥の胸の斑点と似ているから。英語では「toad lily（カエルユリ）」。カエルの模様に似ているからだそうです。
