Background on Mosses

Mosses are non-vascular plants in the division Bryophyta. Unlike other land plants, they lack true roots, stems, and leaves. Instead, they have rhizoids that anchor them and absorb water and nutrients. Mosses reproduce via spores rather than seeds and are found in diverse habitats worldwide, from arctic tundra to tropical rainforests. There are over 12,000 known moss species.

Morphology and Identification

Jackiella javanica var. cavifolia is a small, leafy liverwort moss. Its leaves are deeply concave (hence the name cavifolia meaning “hollow leaves”) and only 0.5-1 mm long. The leaves are arranged in two rows and have a distinctive sickle shape. Jackiella moss is dioicous, meaning male and female reproductive structures are on separate plants. The spore capsules are round and raised on stalks called setae.

Global Distribution and Habitat

This moss has a wide distribution across Asia, Australia, and Oceania. It is found in countries like Indonesia, Malaysia, Philippines, Papua New Guinea, and Australia. Jackiella moss typically grows on tree trunks, branches, and logs in humid montane forests at elevations of 1000-2500 meters. It prefers shaded habitats with high moisture.
