The Missouri Botanical Garden has placed online a recent, data-rich publication on botanical research in the Neotropics. This publication describes two new species of Clusiella, (one from Costa Rica and Panama, C. isthmensis, and one from Brazil, C. impressinervis); it places one old species from Colombia (C. cordifolia Cuatrecasas) in synonymy; and it brings all eight species in the genus together in a key. The publication is written by Dr. Barry E. Hammel and includes several clear, black-and-white photographs as illustrations for the keys.
