Abstract Graffenrieda glandulosa can be distinguished from other species in the genus by 3-nerved leaves with barbate nerve bases on abaxial surface, calyptrate calyx, and short connective appendages covered glandular trichomes. This new has been collected only western tip of state Acre, Brazil, near border Peru.
A new species of Miconia from Brazilian Cerrado vegetation is described and illustrated. astrocalyx belongs to the “Miconia albicans clade”, which part section subsection Seriatiflorae. This can be distinguished in this by stellate yellowish indumentum on branches abaxial leaf surface, large calyx lobes persistent fruit, petal margins with glandular-stipitate trichomes, connective appendages ventrally slightly bilobed a very small dorsal inconspicuous tooth. Additionally, we provide comments...
