Impatiens lobulifera (Balsaminaceae), a New Species from Limestone Areas in Guangxi, China

中國廣西石灰岩地區鳳仙花屬一新種:裂萼鳳仙花

摘要


本文報導了中國廣西壯族自治區西南部石灰岩地區的鳳仙花屬(Impatiens)一個新種:裂萼鳳仙花(I. lobulatifera);提供了線繪圖與彩色照片以資辨識;並報導其種皮和花粉微形態資料。該種在莖肉質、總花序柄4-5 mm長、花近簇生以及翼瓣的上部裂片相互聯合等特徵與具疣鳳仙花(I. verrucifera)略似;但裂萼鳳仙花葉卵形或卵圓形、總花柄具4-5花、花黃綠色、外面的側生萼片卵圓形、裏面的側生萼片卵狀披針形以及頂端具4個指狀的裂片可與之區別。

Impatiens lobulifera (Balsaminaceae), a new species from limestone areas in southwestern Guangxi Zhuangzu Autonomous Region, China, is described and illustrated. The characters of its seed micromorphology and pollen morphology under SEM are given. It is similar to I. verrucifera in having succulent stems, peduncles 4-5 mm long, tufted pedicels and connate distal lobes of lateral united petals, but differs in having ovate or ovate-orbicular leaf blades, 4-5-flowered peduncle, yellow-green flowers, outer lateral sepals ovate-orbicular, inner lateral sepals ovate-lanceolate and topped with four finger-like lobes.
