Southeast Asia represents a major center of diversity for ferns and lycophytes. Within this flora, the genus Selaginella comprises some of the most taxonomically challenging groups, frequently characterized by ambiguous, continuous, or cryptic morphological traits. These complexities commonly lead to misidentifications in both herbarium collections and the published literature. A comprehensive revision of herbarium specimens deposited in Russian and Vietnamese institutions has yielded significant clarifications and new records. Our study documents several previously unreported occurrences: Selaginella subdiaphana, S. subeffusa and S. submonospora are newly recorded for the flora of Vietnam, and S. pulvinata is reported for the first time in Laos. Furthermore, we identify novel, specific distribution points for S. bodinieri and S. coriaceifolia in Vietnam, and for S. doederleinii and S. mairei in Laos. To stabilize taxonomic nomenclature, lectotypes are designated for S. mairei and S. elephantopus.
Шалимов А.П., Зайков В.Ф., Скапцов М.В., Аверьянов Л.В., Дан В.С., До В.Х., Чжан М.-Х., Чжан С.-Ч. Новые находки видов рода Selaginella (Selaginellaceae) в Лаосе и Вьетнаме. Юго-восточная Азия – один из центров разнообразия папоротников и плауновидных. Среди них род Selaginella является одной из наиболее сложных таксономических групп, представители которой часто обладают изменчивыми и недостаточно ясными отличительными признаками. В результате этого в гербариях и публикациях часто встречаются ошибочные определения. Изучение гербарных образцов в российских и вьетнамских гербариях, позволило нам обнаружить несколько новых находок видов рода для флоры Вьетнама и Лаоса. При этом виды Selaginella subdiaphana, S. subeffusa и S. submonospora были впервые найдены во Вьетнаме, а вид S. pulvinata впервые отмечен для Лаоса. Кроме того, мы нашли новые местонахождения S. bodinieri и S. coriaceifolia во Вьетнаме и S. doederleinii и S. mairei в Лаосе. Предложена лектотипификация для S. mairei и S. elephantopus.
