Diagnostic Description

A. espigonensis seems closely related to A. gardneri Baker (loc. cit.). It differs from it in the herbaceous, thin-textured leaves, which are scattered along the vegetative stem. The writer examined a photograph of the type specimen of A. gardneri: It shows a vetative stem and a flower stem; the former displays a low number of somewhat crowded, flexuose, coriaceous, or at least firm-textured leaves; the latter bear flowers with narrower tepals than in the present species.

Distribution

Known from the Espigao Maestre massif, about 100 km WSW of Barreiras, Bahia state, Brazil, and from Serra dos Pirineus, E of Piren6polis, Goias state, as well; altitude 7 50-1000 m.
