耳果相思的耳果 the fruit of earleaf acacia/earpod wattle

耳果相思與香港種植繁多的樹種台灣相思是同科同屬的,所以他們某些特徵相近,如開黃色毛絨的花, 如他們的真葉只出現在幼苗時期,成樹茂密的是葉柄進化的「假葉」。 耳果相思在香港的郊區和市區常見,是常綠喬木。原籍澳洲、南亞。 此樹的「假葉」呈闊鐮刀形,有三、四主脈。穗狀花序,橙黃色細小花數枚簇生於葉腋或枝頂。 立即介紹本文的主角,耳果相思的莢果。何其有趣的造型,扭彎再扭彎,植物科學前輩認為像耳朵故命名。我則覺得像搖鼓,特別是果成熟木化後。這照片是本星期拍的,果實非常鮮嫩,帶著新生的粉綠色。 acacia is a very common planting species in hong kong. back in the 1970s formosa acacia was one of the top three species planting in our country parks as well as in the city. earleaf acacia shares the same family and genus with formosa acacia and it is also common...

雙翼豆 yellow flame tree (peltophorum pterocarpum)

影樹(鳳凰木)花期結束 《維園火焰 》,到雙翼豆吐艷。將兩者相提,因她們同目同科(豆),傘形樹冠,二回偶數羽狀複葉都相似。且兩者英文俗名均取材火焰,一紅一黃。 yellow flame trees just started blossoming. i have spotted quite many of them these few days on hong kong island. at victoria park, in central. if you see some handsome-built trees around the city, rich in bipinnate leaves and attractive yellow flowers in large compound racemes, they are the one. 在不開花時要分辨兩者,參考維基:看葉,盾柱木的小葉片較鳳凰木寬大、數量較少,且沒有羽葉般的托葉著生於葉柄基部;盾柱木的嫩枝披銹色毛,而鳳凰木則枝條光滑。 返回今天的主角雙翼豆,過去幾天,走在香港島街頭,不時發覺她們的影蹤。樹冠茂綠的羽狀複葉,樹頂像插上金黃頭釵的就是她們。 雙翼豆,名來有因,指其莢果邊緣具翅。另名盾柱木,則指其盾狀花蕊,正式來說是其綠色雌蕊柱頭。...

近個多月,在濕地公園一草地上,留意到一叢紅色的乾草。走近細看,果實異常有趣,像小女孩的玩具首飾般。 in the past month or so, a bunch of dry herb on a lawn at the wetland park has drawn my attention. the pods are so curiously looking, almost like some toy jewelry. 花了好陣子搜尋,終於知悉此為扭莢山綠豆。然後比對我的照片庫,果然,夏天已邂逅其花期。 It spent me some time to look up this plant - beggar weed.

鐵刀木 kassod tree (senna siamea)

寫此文前先查看以前有否寫過鐵刀木。 有。去年10月。證明鐵刀木的花真的美,每次遇著便拜倒。 seeing kassod blossoming lately, decided to write about it. i have the habit of checking whether i’ve written the subject before. ha! last year around the same time, i was impressed by the beautiful bloom and made a post about the tree. 鐵刀木在香港是蠻常見的植樹。較大型公園一定有她的蹤跡。因為她容易生長,高大,常綠樹葉優美茂密。鐵刀木原產南亞,拉丁學名senna siamea蘊藏暹羅地名可知;中國亞洲其他地區也可找到。 kassod is quite commonly planted in this city. because it grows...
