Rhytidophyllum

Rhytidophyllum is a genus of flowering plants in the family Asteraceae, commonly known as the daisy or sunflower family. The genus is native to South America, with most species found in the Andes Mountains. Plants in this genus are typically herbaceous perennials, though some can be shrub-like. They are characterized by their toothed or lobed leaves and their composite flower heads, which usually feature yellow ray florets and a darker disk. The name Rhytidophyllum comes from the Greek words "rhytis" meaning wrinkle and "phyllon" meaning leaf, referring to the textured or wrinkled appearance of the foliage in some species.

Species within Rhytidophyllum are often found in alpine and subalpine habitats, growing in grasslands, rocky slopes, and open woodlands. They are adapted to cooler climates and can tolerate a range of soil conditions, though they generally prefer well-drained soils. The flowers of Rhytidophyllum are pollinated by insects, and the fruits are achenes, typical of the Asteraceae family. While not widely cultivated, some species may have local uses or ornamental value. Further research is ongoing to understand the full diversity and ecological roles of plants within this genus.
