三角槭 trident maple (acer buergerianum)

從前每年秋冬旅遊季,大家都去美加看楓紅,然後大家懂得走近點到日本韓國以至台灣,跟著香港人知道香港地有大棠。大家的常識增長了,懂得大棠看的是楓香不是真正的楓樹。

但我們並非沒有楓樹。先讓大家認一個字 -槭。此字可說是楓樹植物學上的正字,也是其屬名。

認識三角槭,絕對因為香港公園。在蜻蜓池附近斜坡有好幾棵,園其他範圍也有。此樹原生於華東及台灣、日本。但我較少在郊野留意到她。我們對楓葉深刻印象是五裂分明巴掌大,而三角槭卻有亞洲的特性,較小巧,而且是三裂的。

參考《認識植物。莊溪》網頁,植物特徵如下:

落葉喬木,枝條光滑,主枝直立。掌狀三裂葉,對生,葉基呈圓形。落葉變紅。繖房花序,花頂生,五單瓣,黃白花,開花後隨即結出成對之翅果;三角槭  trident maple (acer buergerianum)果水平展開,熟時黃綠色。

可惜我常到香港公園探訪此樹,未遇過花盛開的時間。日後要多加注意。

此季看到紅葉也可觀察其翅果。

when i was a kid, when people talked about nature spectacle and travel aboard, go canada to catch the autumn maple was a must. later people travel closer, to japan, korea and taiwan. but don’t you know that we have our own maple.

unlike the typical canadian maple that have five separated lobes and sharp edges on the leaves, trident maple – a native to eastern china (, japan & taiwan) – are smaller in size as a tree as well as of the leaves.

it is a small to medium-sized deciduous tree. the leaves are in opposite pairs, usually with three lobes; on mature trees the lobes forward-pointing and with smooth margins, on young trees with more spreading lobes and serrated margins. the flowers are produced in spring, yellow-green, in pendulous corymbs; they are small, with five greenish sepals and five yellow-white petals and eight stamens. the fruit is a samara with two-winged seeds; the wings are forward-pointing and often overlapping each other.

even though it is a china native, i realize its existence from the hong kong park and not in the wild. every winter they display a pretty spectacle on a slope near the dragonfly pond in the park and i never miss it. but i have to admit i have been paying attention to them during winter too much, i am yet to catch their flowering season. i am making a note to check it out later in the year.

meanwhile, check out trident maple beautiful winter red and their lovely samara.
