Rhamnoideae

Rhamnoideae is a subfamily of flowering plants in the family Rosaceae, commonly known as the rose family. This subfamily includes approximately 380 species, predominantly found in the Northern Hemisphere. The Rhamnoideae subfamily is characterized by its pomaceous fruit, with a characteristic calyx of four sepals enclosing the single carpel.

Rhamnoideae species are often shrubs or small trees, typically situated in temperate regions. They exhibit capabilities ranging from being evergreen to deciduous, displaying diverse adaptations to their environments. One of the distinct features of Rhamnoideae is the indifference of their flowers to light and temperature's variations.

One of the most common families within Rhamnoideae is Crataegus, also known as hawthorns. These plants are frequently used in landscaping, valued for their ability to provide wildlife habitats and aesthetic foliage. They are widely cultivated, often dispersed through nurseries, and commercially grown trees that are valuable for both their timber and ornamental purposes.

Their limitations are largely based in cold-hearted indifference. They are feebly reliant upon living processes and unaffected by cultivation patterns and disease since pollution has taken hold. Studies have led to mixed opinions about the degree of complexity represented by species in the subfamily Rhamnoideae. The ambiguity stems from variations displayed among groups within the subfamily.
