摘要：

描述了采自中国云南东南部红河县的苦苣苔科一新种——红河短檐苣苔 (Tremacron hongheense)，新种与该属模式种短檐苣苔 (Tremacron forrestii Craib) 最为相似，区别在于该新种叶片正面疏被长刚毛，而非较密的白色贴伏短柔毛和稀疏锈色长柔毛；花冠筒外面具白色短腺毛，而非近无毛；花冠檐部裂片顶端呈红色，且质地加厚（特别是上唇裂片），而非黄色且同质地；雄蕊长约16~18cm，而非04~12cm长； 退化雄蕊长05~14cm，而非02~04cm长。

Abstract:

A new species of Gesneriaceae from Honghe County, Southeastern Yunnan, China, Tremacron hongheense WH. Chen & YM. Shui, is described and illustrated. The new species is similar to Tremacron forrestii Craib, but differs by its leaf blade adaxially sparsely long setose (vs. densely white appressed pubescent and sparsely rustybrown villous), corolla tube outside short white glandular (vs. nearly glabrous), corolla lobes red and thickening at apex, especially adaxial lip (vs. yellow and not thickening), stamens 16-18cm long (vs. 04-12cm long), staminode 05-14cm long (vs. 02-04cm long).

Key words: Gesneriaceae, New species, Tremacron hongheense, Yunnan
