A New Calyptranthes (Myrtaceae) from Nicaragua

In preparation for the treatment of Calyptranthes (Myrtaceae) for the Flora de Nicaragua, a summary and identification key to the five known species from the country are presented. One of these, Calyptranthes amarulenta B. Holst, a new species from central Nicaragua, is described and illustrated. The new species is characterized by having bicolorous leaf blades when dry that are rounded to obtuse at the apex, a biconvex midvein on the upper leaf surface, and a glabrous inflorescence.
