戊子初秋廿有
一日於庭園折枝一寫
遁甲書曰梧桐ハ可知日月ノ正閏ヲ生十二葉
一邉ニ有葉従下數一葉ヲ爲一月ト至ル上ナ
二月ニ有レハ閏十三葉其小者爲閏云々
青桐ニ則梧桐無實者又似青桐ニ葉
有椏者ヲ名ク■桐ト○此説考可
本草綱目及和漢三才圖會香木類出
梧桐(ゴトウ) 櫬 音親 橐鄂(ユウガク)
一名青如桹梩(アヲニヨロリ)
《割書:アヲギク|》
其實老スレハ則裂開縁(ヘリ)ニ結子ヲ丸藥ニ五桐子ノ大サ程ヲ
云者此實也
故稱ス鳳凰非レハ梧桐ニ不スト棲(トマ)ラ豈亦食フ其實ヲ乎
百舗ヤ桐ノ梢ニ住ム鳥ノ
チトセハ竹ノ色モカハラシ 寂連
本草一家言云
梧桐 阿遠桐
又ヲニヨロエイ
青桐 岡桐 泡桐
葉三岐ハ雌 葉五岐ハ雄 イツサキ

**遁甲書**に曰く:「梧桐は日月の正閏(正月・閏月)を知るべし。十二葉を生じ、一辺に葉あり、下より数えて一葉を一月とす。上(の葉)に至りて二月(ふたつき)あれば閏(うるう)にして、十三葉。その小さきものを閏とする」云々。
青桐(アオギリ)、すなわち梧桐は実なき者、また青桐に似て葉に椏(また)あるものを■桐(■トウ)と名付ける。○この説、考うべし。

その実、老いれば則ち裂け開き、縁(へり)に子を結ぶ。丸薬に「五桐子(ごとうし)」の大きさほどというものは、この実なり。
ゆえに、「鳳凰は梧桐にあらざれば棲(とま)らず」と称す。あに、またその実を食むや。

## Record of Tree Category (木類)
Year of Boshi (*Bosshi*), 21st day of Early Autumn — a branch was taken from the garden and one illustration was drawn from it.

The ***Tonkō-sho*** (遁甲書, *Book of Escaping the Celestial Stems*) states: "The *Aogiri* (梧桐, Chinese parasol tree) can reveal the regular and intercalary months of the solar-lunar calendar. It produces twelve leaves, one on each side; counting from the bottom, one leaf corresponds to one month. If there are two [leaves] at the top, it signifies an intercalary year, with thirteen leaves in total. The smaller leaf is considered the intercalary month." And so forth.
*Seitō* (青桐, *Aogiri*), that is to say, *Gotō* (梧桐) without fruit — and the one resembling *Seitō* with forked (*mata*) leaves — is named ■Tō (■桐). ○ This explanation requires further investigation.

**Gotō (梧桐)** — *Firmiana simplex* (Chinese Parasol Tree)
Alternative names: *Shin* (櫬, pronounced "shin") · *Yūgaku* (橐鄂)
Also known as: *Ao-ni-yorori* (青如桹梩)
《marginal note: Aogiri (アヲギリ)》

When its fruit is old (ripe), it splits open, and seeds form along the edges. What is referred to as being "about the size of *Gotō-shi* (五桐子)" in pill-making refers to these seeds.
Hence the saying: "The phoenix (*hōō*) will not perch except on the *Aogiri* (梧桐)." Does it not also eat the tree's seeds?
