白楸的果 turn-in-the-wind and there are fruit

很喜歡白楸的英文名字:風翻葉白,很有書卷氣,也直接傳神描繪了此樹葉片的特質。

simply love the name, the most poetic plant i ever knew. one almost want to leaf through each piece of leaf, like reading a book.

十月中,秋已深。白楸開始結果,如立體海星的果串連成捧,模樣趣致如外星小怪物伸手撑脚嚷叫。

the fruit season of turn-in-the-wind happens in deep autumn. you might have thought these are the flowers, in fact these are the fruit. they look so animated and spiky, i imagine them being tens of little aliens from the outer space.

白楸是本地原生常綠小喬木,屬於大戟科野桐屬。白色的葉背外,葉基部兩個凸現的腺點,也是標誌。這大戟科的象徵,很有畫感和味道,因為螞蟻等小昆蟲都會趕來舔食葉液。

turn-in-the-wind is native to hong kong. this evergreen tree can be seen everywhere in the wild.

as it is from the family euphorbiaceae, you can easily spot one of the characteristics, the two outstanding beauty spots (macular glands) at the base of each leaf. ants and insects always gather around to suck the sap, adding animation and interaction around.
