Pupulin, F. & G. Rojas. 2006. A new species of Sigmatostalix (Orchidaceae: Oncidiinae) from Costa Rica, and its concolorous form. Orchids (West Palm Beach) 75: 678–684.

 

Abstract. A new species of the genus Sigmatostalix (Orchidaceae: Oncidiinae) from Costa Rica, and its concolorous form, are described and illustrated. Sigmatostalix dulcineae is a close relative of the Colombian Sigmatostalix hermansiana, from which it differs mainly in the ovate pseudobulbs and the distinctly ovate lamina of the lip, only slightly notched at the subacute apex. The affinities of the Mesoamerican taxa in the genus are discussed, and a key to the species of the Sigmatostalix picta group is provided.
