【 摘 要 】

The genus Trigonotis (Boraginaceae) in Taiwan is revised. Three species and one variety, including one new record, T. peduncularis (Trev.) Bentham ex Baker & S. Moore, are recognized. The two closely similar taxa, T. elevatovenosa Hayata and T. formosana Hayata, were formerly treated as separate species. However, based on our critical comparison, the typical phases of them can be separated only by the leaf shape. Therefore, T. elevatovenosa Hayata is now reduced to the rank of variety, and a new combination T. formosana var. elevatovenosa (Hayata) S. D. Shen & J. C. Wang stat. nov. is proposed here. A key to the taxa of this genus in Taiwan along with description, taxonomic notes, and line drawings are provided.
