The genus "Macrocarpaea", with 105 species and two hybrids of 0.5 m herbs, shrubs, epiphytes and small trees to 10 m tall, is the largest genus of the tribe Helieae of the gentian family (Gentianaceae). Species of "Macrocarpaea" have diurnal and nocturnal pollinators, visited during the day by hummingbirds, insects and butterflies, and at night by bats, moths and many different kinds of insects. The common name for the genus is 'Moon-gentian'. No species are known in cultivation.

Characteristics

Species of this genus have white, cream, yellow to green flowers. Most have a large, open campanulate to funnel-form corolla adapted to nocturnal bat pollination. This genus is one of the few of the gentian family that have species with hairs on their leaves.

Distribution

"Macrocarpaea" has a relatively broad distribution in mountainous regions of the Neotropics. The Neotropics comprise the tropical parts of the New World in Mesoamerica and South America. The gentian tribe Helieae, to which "Macrocarpaea" belongs is restricted to the Neotropics. The overall distribution pattern of "Macrocarpaea" is typical of many Neotropical taxa. The genus is basically found in five major geographic regions: the Andes [ranging from Venezuela, Colombia, Ecuador, Peru, to Bolivia] (85 species), southern Mesoamerica [Costa Rica and Panama] (6 species), the Greater Antilles of the Caribbean [Cuba, Dominican Republic, Jamaica] (3 species), the Pantepui of the Guayana Shield [Venezuela, and adjacent regions in Brazil and Guyana] (6 species), and southeastern Brazil (5 species).

Highlighted species

"Macrocarpaea dies-viridis" "Named for the American punk rock music group Green Day, whose music we listened to, especially while driving to localities throughout Ecuador during out 2006 expedition". Published in Harvard Papers in Botany 11(2): 132. 2007. The common name for the plant is "the Green Day moon-gentian".

"Macrocarpaea apparata" Named for the verb to apparate, made popular in the book Harry Potter and the Chamber of Secrets by J.K. Rowling (1998)"When we first found this new species, we could only find sterile individuals. After looking all afternoon, and only just before dusk, we finally found several flowering plants that seem to have 'apparated' in front of us, appearing out of nowhere." Published in Harvard Papers in Botany 8(1): 66. 2003. The common name is the "Apparating moon-gentian". See photos to the right.

"Macrocarpaea pringleana" Named to honour Dr. James Pringle, Plant Taxonomist at Canada's Royal Botanical Gardens in Hamilton and Burlington, Ontario. Dr. Pringle has contributed extensively over a very long and distinguised career to both the systematics of the Gentian family and to floras of South America. Published in Harvard Papers in Botany 9(1): 11-49.
