Viola singularis J.M. Watson & A.R. Flores

Type: ARGENTINA. Provincia de Catamarca, Belén, Río de los Nacimientos , entre rocas, en la orilla del río, mimética, 21-I-1992, Luis A . Del Vitto s.n. ( MERL 55055 ) .

Location:— The true position in Catamarca is sited 600 km to the north and slightly east of the speculative version provided in the protologue ( Watson & Flores 2009).

Information on the water resources of Catamarca, published by the province’s local government ( ETISIG 2014), positions the Río de Los Nacimientos (otherwise known as Río Las Cuevas) north of Belén, above and to the north of Los Nacimientos village. The valley of the Río Villa Vil lies to the west, and both watercourses meet south of Hualfín to form the Río Belén. Several maps we have consulted confirm this geography. We estimate the probable elevation of the viola site at between 3500 and 4500 m. Figs. 1 & 2 .

FIGURE 2. Physical map of the sector in Catamarca Province, Argentina, where Viola singularis is located. Three outlying towns are identified for orientation. A hatched oblong indicates the Río de Los Nacimientos (or Río Las Cuevas) where the viola was discovered. It is situated above the settlement of Los Nacimientos, shown as a white asterisk within a black circle.
