Morphological Evidences for Hybrid of Dumasia (Fabaceae) in Taiwan
Plants intermediate in appearance between Dumasia miaoliensis and D. villosa subsp. bicolor are assumed to be the result of hybridization. Dumasia miaoliensis has the leaf base truncate, leaves glabrous or pubescent, style and gynophore long and glabrous, pods falcate, black and glabrous and seeds y...

Plants intermediate in appearance between Dumasia miaoliensis and D. villosa subsp. bicolor are assumed to be the result of hybridization. Dumasia miaoliensis has the leaf base truncate, leaves glabrous or pubescent, style and gynophore long and glabrous, pods falcate, black and glabrous and seeds yellowish brown. Dumasia villosa subsp. bicolor has the leaf base acute, leaves soft hairy, style and gynophore short and villose, pods terete, yellowish brown and villose and seeds blue. The putative hybrid is more similar to D. miaoliensis, but has terete pods and short gynophore similar to D. villosa subsp. bicolor. Pollen stainability for D. miaoliensis, the putative hybrid and D. villosa subsp. bicolor is 92.5%, 55.3% and 87.4%, respectively. Dumasia villosa subsp. bicolor occurs in the mountains at 500-2500 m. Dumasia miaoliensis occurs only at Chingchieng and Erpenshong between 1100 and 1500 m. The putative hybrid was found intermixed with or growing near the D. villosa subsp. bicolor and D. miaoliensis. |
