Poimoinae

Poimoinae is a subfamily of flowering plants within the family Convolvulaceae, commonly known as the bindweed or morning glory family. This subfamily is primarily found in tropical and subtropical regions, with a significant number of species native to the Americas. The Poimoinae subfamily was previously classified under the family Cucurbitaceae, but it was later reclassified based on molecular and morphological evidence.

Plants in the Poimoinae subfamily are typically herbaceous vines or lianas, characterized by their twining stems and tendrils. These plants often possess simple, alternate leaves and produce flowers that are usually solitary or in small clusters. The flowers are typically actinomorphic, meaning they have radial symmetry, and are often white, yellow, or greenish in color. The fruit of Poimoinae plants is usually a capsule or berry, containing numerous small seeds.

One of the most well-known genera within the Poimoinae subfamily is Poimenes, which includes species such as Poimenes coccineus and Poimenes eximius. These plants are often cultivated for their ornamental value, particularly for their attractive flowers and foliage. However, some species within this subfamily can be invasive and may cause ecological or agricultural problems in certain regions.

The Poimoinae subfamily is of significant interest to botanists and horticulturists due to its diverse range of species and its unique morphological and ecological characteristics. Ongoing research aims to better understand the taxonomy, phylogeny, and evolutionary history of this subfamily, as well as its potential applications in agriculture, horticulture, and medicine.
