Data from: Rungia sinothailandica sp. nov. (Acanthaceae) from China and Thailand

Rungia sinothailandica (Acanthaceae), a new species from Yunnan, China and Chiang Rai, Thailand is described and illustrated. A colour plate, line drawing and distribution map of R. sinothailandica are provided. Rungia sinothailandica is similar to R. pinpienensis H. S. Lo, but differs in the broadly ovate sterile bracts and obovate-elliptic fertile bracts, the crispate and tawny bracts margin, the 2-lobed upper lip of the corolla and puberulent capsule. It is also similar to R. burmanica (C. B. Clarke) B. Hansen, but is easily distinguished by pubescent stems and leaves, the cymbiform-oblong bracteoles and the 2-lobed upper lip of corolla.

中国云南及泰国清莱产爵床科（Acanthaceae）孩儿草属一新种——中华泰孩儿草（Rungia sinothailandica），本文对其进行了正式记述与形态图解。文中附有该种的彩色图版、线条图及分布地图。该新种与平边孩儿草（R. pinpienensis H. S. Lo）形态相近，二者的区别在于：本种具宽卵形不育苞片与倒卵状椭圆形能育苞片，苞片边缘呈皱波状且为黄褐色，花冠上唇2裂，蒴果被微柔毛。此外，中华泰孩儿草亦与缅甸孩儿草（R. burmanica (C. B. Clarke) B. Hansen）相似，但可通过被柔毛的茎、叶，舟状长圆形小苞片以及花冠上唇2裂的特征，将二者轻松区分。
