節果決明 pink and white shower (cassia javanica var. indochinensis) 2014

兩年前寫過美利大廈的節果決明,最近又逢花季。

樹在樓在時勢變。不過美利大廈已經由政府物業變為私人酒店發展項目。

這次再看節果決明,花了不少時間研究其拉丁學名,因為發現另一個名字跟上次找到的不同。

2012年所找到的物種資料,拉丁學名是 cassia nodosa。

這次發現《香港植物標本室》、《樹木谷》等用的都是 cassia javanica l. var. indochinensis gagnep。經過細意對拼不少國際及本地網頁,得出cassia nodosa 的長寫是cassia javanica ssp. nodosa,與cassia javanica l. var. indochinensis gagnep 植物學上均在同一個「種」cassia javanica 之下,基本上非常類近。

從學名可推斷植物原產於爪哇等東南亞之地。欣賞那花,嬌豔粉嫩,倒有幾分像泰國姑娘穿戴傳統的姿色相近。

the pink and white shower at murray building is in full bloom now.

two years ago i posted about this beautiful tree same time this year. i did another round of research this time and found another latin name:

cassia nodosa – the previous name i found; and

cassia javanica l. var. indochinensis gagnep – found lately

after some more web-surfing and digging on the two latin names, to my interest and relief, the two are variations under the same species of cassia javanica. cassia nodosa in more detail should be cassia javanica ssp. nodosa.

isn’t it interesting? the same tree teaches me different things at different times.

i also learnt another common name of this tree, apple blossom.

urban nature adds more dimensions to our appreciation too. two years ago this valuable tree stood inside a governmental site. now the murray building is in the hand of a private company. i worried about this tree for a few months after seeing the site was closed for redevelopment. i was relieved a lot two-three weeks ago after seeing the tree blossoming again, same time this year.
