Taxon discussion

Hypericum acostanum (Fig. 2 A,a) is an endemic species of southern Ecuador. It belongs to the New World section Hypericum Brathys (Mutis ex L.f.) Choisy, which has radiated in the Páramos ( Nürk et al. 2013).

This species is listed as vulnerable (VU) in the Ecuadorian Red List. It is known from only two localities, collected in the 50s and 80s in the province of Loja, on the road between San Pedro and Portovelo and on the road between Celica-Guachanamá, respectively. We confirm its persistence in the second locality and provide an exact location with coordinates. In addition, after studying the QCNE herbarium material, we have re-assigned a specimen (voucher nº 5612) from the rovince of Loja to this species. Therefore, we have added a new locality to the distribution of H. acostanum in this rovince.
