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。
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 Tremacronforrestii 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 1.6-1.8 cm long （ vs. 0. 4-1.2 cm long）, staminode 0. 5-1.4 cm long （vs. 0. 2-0. 4 cm long）.
