備註: 在香港沒有Ficus superba 雀榕(華麗榕)的,在泰國越南等東南亞地方才有。(thanks Crawford's info) 大葉榕(黃葛樹)的近似品種是筆管榕 .留意2者的葉底,前者葉脈突出,後者平滑,很易辨認.information from hktree.com 大葉榕與筆管榕分別其實頗大, 前者的葉較大而闊, 葉背的側脈突出. 但最大的分別在於花/果上. 大葉榕的花總梗/果柄極短或缺. 即榕果貼生在枝上. 筆管榕有長約半厘米左右的花總梗/果柄. 而且大葉榕的果較扁而筆管榕較圓. information from hkwildlife.net 大葉榕與筆管榕也可從托葉及幼葉顏色分別出兩者(156f, 156g)thanks chandd's info FOC: Trees, deciduous. Bark blackish brown. Branches with few aerial roots; branchlets pale red, glabrous. Stipules caducous, lanceolate, ca. 2 cm, membranous, sparsely pubescent. Leaves alternate or fasciculate; petiole 3-7 cm, subglabrous; leaf blade elliptic to oblong, 10-15 × 4-6 cm, ± papery, glabrous, base rounded, margin entire or slightly undulate, apex shortly acuminate; secondary veins 7-9 on each side of midvein. Figs axillary on leafy branchlets, paired or solitary, or in small clusters on older leafless branchlets, purplish black when mature, depressed globose, 5-8 mm in diam., apical pore ± concave; peduncle 3-8 mm; involucral bracts broadly ovate, basally leathery. Male, gall, and female flowers within same fig. Male flowers: few, near apical pore, sessile; calyx lobes 3, broadly ovate; stamen 1; filament short; anther ovoid. Gall flowers: many, similar to female flowers but ovary with a thick long stalk; stigma linear. Female flowers: sessile or pedicellate; calyx lobes 3, lanceolate; style short, lateral; stigma rounded. Fl. Apr-Jun. This species has often been treated as Ficus superba var. japonica, but it is quite distinct from F. superba s.str. which does not occur within the Flora area (Berg, in litt.). Chinese material has also been named as F. tenuipes S. Moore, but we follow Corner, who regarded F. tenuipes as a synonym of F. superba s.str. Chinese records of F. wightiana Wallich ex Miquel were based on misidentifications of this species. | |
