Peperomia dotana is a species of epiphyte in the genus Peperomia that is endemic in Costa Rica and Panama.[1][2] It grows on wet tropical biomes.[1] Its conservation status is Threatened.[3]
Description
[edit]The type specimen was collected in Costa Rica and Panama at an altitude of 1800 meters.[4]
Peperomia dotana is a rather large, rhizomatous, erect, nearly unbranched, hairless herb. The stem is stout at 3 to 6 millimeters thick. The leaves are alternate, somewhat diamond-shaped to lance-shaped, pointed at both ends, and rather large at 6 to 7 by 13 centimeters. They are thick with edges rolled downward, have pinnate veins below, and the delicate branches of the midrib number about 5 pairs by 2. The petiole is rather elongate at 2.5 centimeters long. The spikes are about 4 in number, scattered or bunched on slender branches growing from the leaf axils, with those branches measuring 5 or 6 centimeters long. The spikes are moderately slender and short at 30 to 40 millimeters. The peduncles are about 5 millimeters long. The floral bracts are round and peltate. The berries are gray, ellipsoid in shape, with a stout beak. The stigma is positioned at the front, at the base of the beak.[4]
Taxonomy and naming
[edit]It was described in 1929 by William Trelease in Contributions from the United States National Herbarium.[5] The epithet dotana refers to the Dota region or Dota Valley in Costa Rica, where the type specimen was collected.[4]
Distribution and habitat
[edit]It is endemic in Costa Rica and Panama.[2] It grows as an epiphyte and is a herb.[1][4] It grows on wet tropical biomes.[1]
