Convolvulaceae neotropicae novae vel minus cognitae, II. Ipomoea yaracuyensis , a new species from the cloud forests of the Coastal Cordillera of Venezuela

Ipomoea yaracuyensis (Convolvulaceae: Convolvuloideae: Ipomoeae) is described and illustrated by materials from cloud forests of the Sierra de Aroa and the Macizo de Nirgua of the Coastal Cordillera of Venezuela. This new species can easily be distinguished from other related species by the presence of few-flowered cymes supported by relatively short and arched peduncles, relatively large (2.3–3.1 cm long), subcoriaceous and apiculate sepals, and a yellow corolla ca. 7 cm long. A description of the pollen is also included.
