TY -JOUR AU -Jenn-Che Wang and Chang-Tze Lu TI -Revision of the Genus Swertia L. (Gentianaceae) in Taiwan PY -1998 DA -0000-00-00 JO -Taiwania VL -43 IS -4 SP -273 EP -288 UR -https://taiwania.ntu.edu.tw/abstract/175 AB -The genus Swertia(Gentianaceae) in Taiwan is revised based on morphological study.Four species, namely S. arisanensis Hayata, S. macrosperma (C. B. Clarke) C. B. Clarke (syn. S. randaiensis Hayata), S. shintenensis Hayata, and S. tozanensis Hayata, are recognized. By detailed comparison of type specimens and filed investigation, S. matsudae Satake, which was previously treated as distinct, is now reduced to the synonymy under S. tozanensis Hayata. Nectaries on coroll-lobes are the most important characters in separating the Taiwanese taxa. Habit, calyx-lobe, seed number per capsule, and seed morphology also display interspecific variation and provide valuable taxonomic significance. A key to the taxa along with descriptions, illustrations, and taxonomic notes are provided. DO -10.6165/tai.1998.43(4).273
