Riccia teneriffae S.W.Arnell, a moss in the Ricciaceae family. Also known simply as Riccia, this diminutive plant is worth taking a closer look at.
Background on Riccia Mosses
The genus Riccia contains around 150 species of thallose liverworts. These non-vascular plants lack roots, stems, and leaves. Instead, they have a flattened, lobed structure called a thallus. Riccia are found worldwide, from the Arctic to the tropics.
Morphology and Identification of Riccia teneriffae
7206 from: https://biodiversite.cevennes-parcnational.fr/espece/6210
R. teneriffae has a small thallus that is light green in color. The thallus is deeply divided into narrow, strap-like lobes. When dry, the lobes curl inward. This species can be distinguished from similar Riccia by its delicate, membranous thallus margins.
Global Distribution and Habitat
R. teneriffae has a scattered global distribution. It is found in parts of Europe, Africa, Asia, and South America. This species typically grows on damp, exposed soil or thin soil over rocks. It favors open, sunny habitats.
Ecological Roles and Adaptations
Like other mosses, R. teneriffae plays important roles in its ecosystem:
- Helps retain moisture in the soil

- Provides shelter for tiny invertebrates
- Acts as a pioneer species in disturbed areas

- Serves as a food source for some small herbivores
To survive in its often harsh habitats, R. teneriffae has several adaptations:
- Curling lobes to reduce water loss when dry
- Rhizoids to anchor it to the substrate
- Ability to dry out and rehydrate quickly
- Asexual reproduction via fragmentation
