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

Gentianaceae

Gentianaceae are a family of flowering plants of 87 genera and over 1500 species. Flowers are actinomorphic and bisexual with fused sepals and petals. The stamens are attached to the inside of the petals and alternate with the corolla lobes. There is a glandular disk at the base of the gynoecium,...

). 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).

"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.
