Begonia blancii (sect. Diploclinium, Begoniaceae), A New Species Endemic to the Philippine Island of Palawan
特產菲律賓巴拉望島之秋海棠屬（秋海棠組）一新種：匙葉秋海棠
摘要
本文發表特產菲律賓巴拉望島的秋海棠屬（秋海棠組）一新種：匙葉秋海棠。此新種略似產於菲律賓之秋海棠組具二室子房的B. suborbiculata，但新種具有平鋪於裸岩之垂直壁面的肉質三角形匙狀葉片而明顯可以區別。匙葉秋海棠為常綠性，如同若干生長於相似生境的秋海棠，其葉片具有聚生的氣孔，此殆與減少旱季時的水分蒸散有關。本文並報導本新種與近緣種之染色體數與核型：B. blancii(2n=30)，B. suborbiculata(2n=30)，以及B. gueritziana（2n=28；婆羅洲產）。根據世界自然保育聯盟(IUCN)的評估標準，匙葉秋海棠屬於「安全」等級。

A new species of Begonia in sect. Diploclinium, B. blancii M. Hughes & C.-I Peng, is described from the Bulalakaw Falls area in Palawan. A somatic chromosome number of 2n=30 was determined. Begonia blancii is allied to B. suborbiculata and other 2-locular species in Begonia sect. Diploclinium, but is very distinct in having triangular-spathulate leaves. It shares clustered stomata with a number of other Begonia species, which are likely to help it reduce water loss through transpiration during the dry season. Its IUCN status is considered to be Least Concern.
