摘要

Ipomoea macdonaldii is described as a new species apparently endemic to the southern coast of the state of Oaxaca, Mexico. This herbaceous vine has white, nocturnal flowers with exserted stamens. It occurs in lowland, subdeciduous forests at altitudes mostly less than 200 m, but occasionally up to 1000 m. It belongs to sub-genus Eriospermum, and is closely related to Ipomoea lottiae. A description with notes on the ecology of the new taxon is presented. A drawing of the new species is presented along with ecological information.Digital Object Identifier http://dx.doi.org/10.1007/s12228-010-9131-7
