| 備註: 標室: 山蟛蜞菊 Wedelia wallichii Less. 應是指另一品種. FOC: 山蟛蜞菊 Indocypraea montana (Blume) Orchard [SYN: Wollastonia montana (Blume) Candolle, Prodr. 5: 547. 1836.] 是香港所見. 之前將山蟛蜞菊誤認為百能葳Blainvillea acmella 中國沒有百能葳屬 Blainvillea (Asteraceae-Heliantheae) is absent from China 香港所見都是 Indocypraea montana (Blume) Orchard [SYN: Wollastonia montana (Blume) Candolle, Prodr. 5: 547. 1836.] 山蟛蜞菊 LINK: 生活型： 草本，有時攀援狀； 莖： 莖被糙毛或下部脫毛； 葉： 葉卵形或卵狀披針形，連葉柄長10-13厘米，邊緣有不規則鋸齒或重齒，上面被糙毛，下面毛較密，葉柄長0.5-4厘米：上部葉披針形，長2.5-6厘米，有短柄或無柄； 花： 頭狀花序少數，徑2-2.5厘米，每2個腋生，或單生枝頂，花序梗長2-3厘米，被白色糙毛；總苞寬鐘形或半球形，徑約1.5厘米，總苞片2層，外層長圓形或倒披針形，長約8毫米，密被長粗毛，內層長圓形或倒卵狀長圓形，長5-6毫米，被疏毛；托片先端芒尖或芒狀刺尖，背面及上部邊緣被粗毛；舌狀花1層，黃色，舌片卵狀長圓形；管狀花多數，黃色，裂片三角狀漸尖； 果： 瘦果倒卵圓形，背腹略扁，密被白色撫突，頂端圓，收縮部分密被毛；冠毛短剌芒狀，2-3個，基部有冠毛環； FOC: Perennial herbs. Stems erect, stout, glabrous or scabrid. Leaves petiolate; petiole 1-2 cm; blade ovate or ovate-lanceolate, (3-)5-9 × (1-)3-4 cm, both surfaces scabrid, base rounded or cuneate, margin crenulate, apex acuminate. Capitula ca. 15 mm in diam., solitary on elongate peduncle; involucre campanulate, 7-10 × 4-5 mm; outer phyllaries papery, green, oblong, ca. 10 mm, dorsally scabrid, apex obtuse or shortly acute, inner phyllaries oblong to lanceolate, ca. 7 mm, dorsally pubescent in upper part, apex acuminate; paleae oblong, sparsely pubescent. Ray florets 1-seriate, yellow; lamina oblong, 4-6 × ca. 2 mm, apex 2- or 3-toothed. Disk florets tubular, yellow. Achenes red-brown, obovoid-trigonous, slightly compressed, ca. 5 mm; pappus elements 2 or 3. Fl. Apr-Oct. Two taxa are represented among the material cited by Candolle under Wollastonia montana. That representing Blume’s concept of Verbesina montana certainly does not belong to Melanthera, and it is felt better to include it here within the concept of Wollastonia. It should also be noted that Wedelia wallichii var. megalantha is not conspecific with type material of W. wallichii but appears to be Wollastonia biflora. | |
