Plant repent, ascending or descending. Inflorescence loose, successively flowered or successively single-flowered. Ovary papillose or spiculate, glabrous in one species. Lip three-lobed (sometimes inconspicuously), a few species with the midlobe transformed into what is possibly performing the same function as the appendix in Lepanthes . Anther and stigma apical. Column foot absent. Pollinaria with a drop-like viscidium. Four species, distributed through the Andean regions of Colombia, Ecuador, Peru and Bolivia ( Fig. 6 ), with an elevation range of 2,400 to 3,825 m ( Fig. 8 ). An example, Andinia lappacea (Luer) Pridgeon & M.W.Chase , is illustrated ( Fig. 11c ).

FIGURE 8. Mean elevations and elevational ranges of collections from Tropicos for proposed subgenera Andinia; Aenigma; Masdevalliantha; Minuscula; all four subgenera combined (i.e. excluding Brachycladium); and Brachycladium. Blue triangles represent mean collection elevation (m) and black bar represents elevational range of collections.
