Abstract

Sedum dasyphyllum L. has a controversial infraspecific treatment, with three subspecies
distinguished based on the abundance of glandular indumentum. Sedum dasyphyllum L. subsp. glanduliferum
(Guss.) Nyman, characterized by the presence of abundant glandular hairs, was considered a subspecies
with a southern tendency, with very few and unclear records in the northwestern Iberian Peninsula. In the
present study, 56 herbarium sheets from the LEB FCO and SANT herbaria were assigned to the taxa Sedum
dasyphyllum L. and Sedum dasyphyllum L. subsp. dasyphyllum were analyzed. Of these, 45 were re-assigned
to Sedum dasyphyllum L. subsp. glanduliferum (Guss.) Nyman, constituting the first records for this taxon
in the provinces of León, Lugo, Oviedo, Orense, Palencia, and Santander. Moreover, five sheets were reassigned
to Sedum dasyphyllum L. subsp. dasyphyllum, while another five retained their original assignment
(Sedum dasyphyllum L. subsp. dasyphyllum). The populations are now identified as Sedum dasyphyllum L.
subsp. glanduliferum (Guss.) Nyman do not appear to occupy more southern enclaves or southern slopes,
although they are, on average, found at higher altitudes within the study area.
Keywords: Glandular indument, LEB herbarium, northwestern Iberian Peninsula, preserved plants, province
of León, Sedum dasyphyllum subsp. glanduliferum.
