Fig. 2. Field photographs of Merianthera calyptrata R.Goldenb., Bochorny & Fraga sp. nov. A. Fertile branch. B. Branch apex, longitudinal section showing the fistulose structure of the stem, with the chambers filled with parenchyma. C–E. Sequence of flower anthesis, showing the calyptrate calyx with its circumscissile dehiscence. F. Flowers, frontal view. G. Stamens and style, lateral view. H. Old flower, lateral view; this photo shows the single, ebracteolate flower and the absence of a peduncle. I. Mature fruit. From: Fraga & Couto 4144 (A–H), Amorim et al. 11854 (I). Photos by C.N. Fraga (A–H) and Y. Gouvea (I).
Fig. 1 in Merianthera calyptrata sp. nov. (Melastomataceae, Myrtales), a new candelabriform species from Minas Gerais, Brazil
Fig. 1. Illustration of Merianthera calyptrata R.Goldenb., Bochorny & Fraga sp. nov. A. Fertile branch. B. Detail of the branch showing leaf and flower scars plus two lenticels, each at one side of the leaf scar. C. Branch tip with leaves, flower buds, an open flower and a fruit. D. Flower opening sequence, from left to right: flower bud, with the calyptrate calyx still attached to the hypanthium; flower bud, with a circumscissile dehiscence, but the calyptra still holding the petals together; and young flower, with the calyptrate calyx falling from the petal tips. E. Petal, adaxial surface. F. Flower in longitudinal section (calyx, petals and stamens removed) with detail of trichomes at the base of style. G. Antesepalous stamens, from bud (left) and mature flower (right). H. Antepetalous stamens, from bud (right) and mature flower (left). I. Antepetalous stamen, detail of the pore. From Fraga & Couto 4144 (all drawings). Drawn by Diana Carneiro.

Fig. 4. Merianthera calyptrata R.Goldenb., Bochorny & Fraga sp. nov. in its habitat. A. Inselberg and granitic outcrops where the plant can be found. B. Vegetation cluster growing on a cleft, on a granitic outcrop, with M. calyptrata to the right and front, with flowers. C. Three individuals with spreading crowns, behind some Alcantarea (É.Morren ex Mez) Harms (Bromeliaceae). From Fraga & Couto 4144. Photos by C.N. Fraga.
