A new subspecies ofArenaria grandiflora (Caryophyllaceae) from the Rif mountains (Northern Morocco)

subject

description

A new subspecies,A. grandiflora subsp.gomarica (Caryophyllaceae), is described from the mountains of northern Morocco. The new taxon is tetraploid and has been confused in the past either with the Balearic endemicA. grandiflora subsp.glabrescens or with the widespreadA. grandiflora subsp.grandiflora, which is also present in the African continent. Detailed morphological analysis showed that plants from the Rif mountains are closely related toA. grandiflora subsp.glabrescens, but differ from it in having a longer calyx, smaller seed size, and a glandular indument on pedicels, leaves and calyx.Arenaria grandiflora subsp.gomarica can be distinguished from all infraspecific taxa of theA. grandiflora complex by the combined presence of a heterotrichous (simple and pluricellular eglandular hairs, glandular hairs) indument on the inflorescences and glandular hairs on the calyx.
