Achrophyllum haesselianum (Matteri) Matteri, a moss in the Daltoniaceae family. In this blog post, we’ll dive into the details of this fascinating plant.
Background
Achrophyllum haesselianum is a species of moss first described by Celina Maria Matteri in 1973. It belongs to the genus Achrophyllum and the family Daltoniaceae. Mosses are non-vascular plants in the division Bryophyta, class Bryopsida.
Morphology and Identification
A. haesselianum forms loose mats. The stems are creeping to ascending, irregularly branched, and up to 3 cm long. Leaves are ovate-lanceolate, 1-2 mm long, with serrate margins and a short, double costa. The leaf cells are short and rhomboidal. Sporophytes have not been observed for this species.
Global Distribution and Habitat
This moss is native to southern South America, including Argentina and Chile. It grows on soil, rocks, logs, and tree bases in humid forests from lowlands to mountains. The species is not considered threatened.
Ecological Roles and Adaptations

Like other mosses, A. haesselianum plays important roles in its ecosystem:
- Helps retain moisture and prevent erosion

- Provides shelter and food for small invertebrates
- Participates in nutrient cycling
- Acts as a pioneer species in disturbed areas
The moss has adaptations like water-absorbing leaf surfaces, rhizoids for anchoring, and desiccation tolerance to survive in its environment.
