Dendropanax Trifidus 隠れ蓑（カクレミノ）

英語の後に日本語が続きます。

The Dendropanax trifidus is native to east Asia and can be found across Japan. The tree produces male and hermaphrodite flowers from June to July and then fruits, which turn black purple in late autumn. 

Its Japanese name is "kakuremino," which translates into "invisibility cloak," after the leaf looking like Tengu's magic cloak, which makes the wearer invisible like Harry Potter's invisibility cloak. Tengu are a type of mischievous yokai (supernatural beings) appearing in Japanese folklore. Imagining Harry Potter wearing Tengu's cloak made me chuckle😆.

The Dendropanax trifidus leaves change generally from a lobed to an ovate shape but some aren't lobed or ovate, which makes it difficult to identify the tree.

Lespedeza (Bush Clovers) 萩（ハギ）

英語の後に日本語が続きます。

The bush clover is native to east Asia and can be found across Japan. It's known as an autumn plant in Japan and its Japanese name "hagi" is a kigo or a seasonal word or phrase associated with a particular season used in traditional forms of Japanese poetry for autumn, but bush clovers actually flower from July to September and I once found a tree flowering in December (scroll down).

Bush clovers are known to produce pink flowers but they also have white flowers (Lespedeza buergeri) and some (Lespedeza  japonica bailey cv. versicolor) produce pink and white flowers on the same tree.

Broadleaf Plantain (Plantago Major) セイヨウオオバコ（西洋大葉子）

英語の後に日本語が続きます。

The broadleaf plantain (Plantago major) is native to Eurasia while the Chinese plantain (Plantago asiatica) is native to east Asia and both can now be found across Japan. The former is larger than the latter but otherwise they resemble each other very much, so I can't tell which those in these photos are. The Plantago major flowers in summer and the Plantago asiatica from April to September in Japan. When I took these pictures, most had no flowers but I found one with many tiny cream flowers drooping after rain.

Sawtooth Oak (Quercus Acutissima) クヌギ（櫟）

英語の後に日本語が続きます。

The sawtooth oak (Quercus acutissima) is native to North East Asia and can be found across Japan. The tree is known for its acorns but its calybia and cupules are beautiful and so are its flowers, produced from April to May (scroll down), which always remind me of a "noren" or bead curtain hung at the entrance of many izakaya restaurants in Japan😆.     

By the way, the term "noren" has another meaning in Japan, that is, goodwill for accounting and tax purposes because noren, which often has a trade name on it, is believed to represent customers' trust and brand value. Noren or goodwill is generally amortized over 20 years or less under Japanese GAAP and 5 years for Japanese tax purposes but not amortized but impaired when devalued for IFRS purposes. Why so different?  

As a relatively conservative country, Japan has preferred to take a conservative approach that goodwill, i.e., value in excess of market value, should decline as time goes by. Japan also doesn't like an impairment test, which could be manipulated by the management. Which approach would you choose?
