Discussion

Shoots of Campylium stellatum often look like small stars when seen from above in the field. The species is closely related to C. protensum, from which it differs in having a more erect growth, slightly larger size, and relatively shorter leaf acumen. Paraphyllia have never been seen in C. stellatum, whereas scattered plants of C. protensum have a few paraphyllia.
