Abstract
This paper presents a re-evaluation of the taxonomic relationships of Silene sericea var. balearica based on morphological features Critical examination of herbarium specimens (including type material) and living plants has shown that S. sericea var. balearica should be recognized at species level. Therefore, the new name, Silene migjornensis, is proposed to designate the endemic species growing on maritime sands in southern Mallorca (Balearic Islands, Spain). This taxon is described, illustrated and compared with its morphologically closest relatives from Silene sect. Dipterosperma.
Highlights
Silene L. (Caryophyllaceae) is a large genus of flowering plants, distributed mainly across the Northern Hemisphere
The genus is diverse around the Mediterranean Basin where more than 350 species have been recorded (Greuter et al, 1984)
Our study of the type material of S. sericea var. balearica preserved at COI and living plants from the type locality show that the stems of this taxon are prostrate-ascending, the flowers are solitary and the seed wings are flat
Summary
Silene L. (Caryophyllaceae) is a large genus of flowering plants, distributed mainly across the Northern Hemisphere. This section comprises annual plants, characterized by hairy-pubescent (nonglandular) indumentum, erect flowers, arranged in monochasia or dichasia, calyx hairy, not inflated, 10-nerved, anthophore pubescent, petal limb deeply bifid, coronal scales present, seeds orbicular-reniform, laterally flat and dorsally furrowed between two more or less undulate wings (Talavera, 1990; Brullo et al, 2012, 2017).
