Habitat: —In the shaded grasslands in broad-leaved forests, also on rocks on slopes or river valleys. 800–3700 m . Distribution: — China ( Anhui , Gansu , Guizhou , Henan , Hubei , Shaanxi , Shanxi , Sichuan , Taiwan , Tibet, Yunnan). Note: —This species is widely distributed in China . It is similar to Goodyera repens (L.) R.Br. ( Fig. 4. C–I ) but can be distinguished on the basis of rosulate leaves with more or less reticulate silvery veins and irregular markings on the upper surface, a much longer and more slender inflorescence (up to 20 cm long) and narrower lateral sepals (less than 2.0 mm wide). Lang (1978) proposed a new species, G. bomiensis , and noted that it is similar to G. repens and with rosulate and thicker leaves, but he did not mention G. brachystegia . We assume he may not have been able to study any material of the type of G. brachystegia , which is preserved at WU. A thorough analysis revealed that both plants have rosulate ovate-orbicular leaves, slender inflorescence with small flowers which have narrowly elliptic lateral sepals. Goodyera bomiensis was newly recorded from Taiwan in 2009 (Chung and Hsu, 2009). During our studies we found that the individuals from Taiwan have fewer flowers than those found in mainland China ; however, other morphological features are the same.
