摘要
<jats:p>Gastrodia Brown (1810: 330) is a mycoheterotrophic genus of Orchidaceae that consists of ca. 50 species (Tan et al. 2012, Suetsugu 2014, Huang et al. 2015). It is characterized by a fleshy tuber or coralloid root system, fused sepals and petals, and two mealy pollinia without caudicles. Since most Gastrodia species have completely fused sepals and petals, observation of the perianth is difficult, and identification of this genus is often imprecise. As a result of re-examination of floral characters, several new taxa in this genus have been reported in China, Taiwan, Japan, Madagascar and other countries during the last decade (Meng et al. 2007, Hsu et al. 2010, Hsu & Kuo 2011, Yeh et al. 2011, Hsu et al. 2012, Tan et al. 2012, Suetsugu 2013, 2014, Huang et al. 2015, Martos et al. 2015). Most of these new taxa belong to the section Codonanthus (Schlechter 1911), which has a short inflorescence (<40 cm).</jats:p>
