Discussion:

Gleason (Rec. Trav. Bot. Neerl. 32: 205. 1037) has elaborated the confusion surrounding A. hedyotidea. I have examined the Kew specimen annotated by Triana and attributed by him to Salzmann; the label reads '' Bahia; in paludibus.—Rhexia microphylla," without collector indicated. Certainly this Bahia specimen is conspecific with A. boissieriana Coejn. The several collections from northeastern South America agree in essential details with Presl's and Naudin's descriptions and plates for Bicranthera hedyotidea and D. sahmannii. Presl's habit sketch shows old hypanthia and flowering hypanthia with no buds and I believe his generic statement concerning absence of petals even in buds is incorrect (indeed unique in the Melastomaeeae, if true).
