Notes on Ipomoea (Convolvulaceae) from Ecuador.

Area of Science:

• Botany
• Plant Taxonomy
• Biodiversity Research

Background:

• The genus Ipomoea (morning glories) is diverse, with many species found in South America.
• Accurate identification and distribution mapping of plant species are crucial for conservation efforts.
• Previous taxonomic treatments of Ipomoea in Ecuador may require revision based on new data.

Purpose of the Study:

• To revise the taxonomy of Ipomoea species in Ecuador.
• To describe new species and clarify the status of existing ones.
• To provide a comprehensive identification key for Ipomoea in Ecuador.

Main Methods:

• Fieldwork and collection of specimens.
• Examination of herbarium specimens and photographic archives.
• Molecular sequencing for phylogenetic analysis.
• Morphological comparisons and detailed descriptions.

Main Results:

• Four new Ipomoea species endemic to Ecuador are described: I. quitensis, I. ceronii, I. condorensis, and I. papyrifera.
• Ipomoea ophiodes is confirmed as distinct from I. regnellii, with mapped distributions.
• Ipomoea amazonica is recorded from Ecuador for the first time.
• A key to 57 Ipomoea species in Ecuador is presented.

Conclusions:

• The study clarifies the taxonomic status and distribution of several Ipomoea species in Ecuador.
• The description of new endemic species highlights Ecuador's unique plant biodiversity.
• The provided key will aid researchers and botanists in identifying Ipomoea species in the region.
