[Botany • 2017] Cohniella cayennensis • Critical Study of the Cohniella (Oncidiinae, Orchidaceae) of French Guiana

Cohniella cayennensis  Sambin & Chiron


The detailed study of several Cohniella specimens observed and/or collected in French Guiana shows that they all belong to a single entity and that it is different from the two species previously cited for this country, Cohniella cebolleta and C. ultrajectina, by a set of significant vegetative and floral characters. This entity is here described as a new species, illustrated and compared with the two taxa mentioned. A distribution map of the hitherto known specimens and/or populations is proposed, as well as an identification key.

Keywords:  Cohniella cayennensis, Botanical Garden of French Guiana, taxonomy, Monocots

Cohniella cayennensis Sambin & Chiron, sp. nov.

Etymology:— the name refers to the city of Cayenne and its surroundings where the type was collected.
