The first ever liverwort and hornwort checklist is provided for the Kepulauan Sunda Kecil (Lesser Sunda Islands) of Indonesia and Timor-Leste (East Timor). We report 129 accepted taxa, 12 doubtful taxa and three rejected taxa previously reported for the Lesser Sunda Islands. The list is based on over 130 literature references, including monographs, regional studies, and molecular investigations. It is clear that bryophytes from this region have been overlooked historically, and under collected, compared to seed plants, birds, and other organisms, forming a remarkable gap in the flora of Indonesia. Publications dealing with liverworts of Lesser Sunda Islands are few and scattered. We predict that further fieldwork, in addition to collections unveiled from regional herbaria, will uncover a number of new records that remain to be reported, especially considering that regionally widespread species have been recorded elsewhere.

群岛中的群岛：Kepulauan Sunda Kecil（小巽他群岛）、印度尼西亚和东帝汶（东帝汶）的地衣和金鱼草清单

为印度尼西亚的 Kepulauan Sunda Kecil（小巽他群岛）和东帝汶（东帝汶）提供了有史以来的第一份地衣和金鱼草清单。我们报告了先前为小巽他群岛报告的 129 个已接受类群、12 个可疑类群和 3 个拒绝类群。该列表基于 130 多篇参考文献，包括专着、区域研究和分子研究。很明显，与种子植物、鸟类和其他生物相比，该地区的苔藓植物在历史上一直被忽视和收集不足，从而在印度尼西亚的植物群中形成了显着的差距。涉及小巽他群岛苔类植物的出版物很少且分散。我们预测，除了从区域植物标本馆公布的收藏品外，进一步的实地调查将发现一些仍有待报告的新记录，
