備註: 大葉杜英 跟 毛果有花的話比較好分,先由最容易觀察的說起:(thanks Crawford Law's info) 1. 毛果杜英雄蕊頂部具芒4-4.5毫米, 而大葉杜英雄蕊頂部不具芒; (芒跟絨毛差很遠,有夠粗的,離遠點都看到,一條雄蕊才得一條芒在頂) 2. 毛果杜英花瓣跟萼片都比較長近一倍有餘,毛果杜英萼片5或6,1.2-1.5厘米,花瓣5或6,1.3-1.5厘米;而大葉杜英萼片長6毫米,花瓣5片,长6-7毫米。 3. 毛果杜英雄蕊45-51;大葉杜英雄蕊28-32枚 (這個我倒沒真的數過,這兩天有空數一下,不過兩者數目差異有夠大) 所以其實到底有沒有真的大葉杜英 在街上倒真的不知道,看來看去都是毛果。 資料來源: http://foc.eflora.cn/cecontent.aspx?TaxonID=250076958 http://foc.eflora.cn/content.aspx?TaxonId=200013516 而有時看毛果杜英,會發現葉形特別是葉尖的部分會有差異,容易引起誤會以為是別的東西。 這部分中文版不知為啥漏了,英文版寫得好清楚,apex shortly acute, rounded, or emarginate. (葉尖 尖,圓跟凹都有) reference 最近知道有款叫 細葉杜英 Elaeocarpus rugosus ‘Microphylla’ 。它是毛果杜英的園藝種,香港有買來種。葉形像毛果的縮水版。間中見到跟水石榕拍埋一齊種。(thanks Crawford Law's info) FOC: Trees to 30 m tall, to 2 m dbh Bark gray; branchlets robust, 6-12 mm in diam., rust-brown puberulent, with conspicuous leaf and infructescence scars.
