  • Description

    Species Description - Plants in loose tufts, yellowish green. Stems to 6 cm high, filiform, with densely appressed foliate leaves. Fertile plants ending in nearly globose perichaetia. Leaves 4-6 mm long, entire, lanceolate, ending in a short hyaline tip, the stem leaves narrowly lanceolate, the perichaetial leaves broadly lanceolate to ovate. Costa filling 1/3 of the leaf width, excurrent, in transverse section with ventral hyalocysts and dorsal groups of stereids, amellose at back. Alar cells not or scarcely differentiated, hyaline or brownish. Basal laminal cells rectangular, hyaline, thin-walled, 6-12 × 25-70 µm, in several rows narrower at margins. Upper laminal cells oval, 5-10 × 10-16 µm, incrassate. Sporophyte not known (?).

  • Discussion

    This species much resembles C. introflexus anatomically and is perhaps derived from the latter species, which is widespread through the temperate and subantarctic regions of the Southern Hemisphere. It differs only by the non-reflexed hairpoints, the appressed foliate stems and the blunt perichaetial leaves.

    In Africa this species occurs as ssp. arbogastii (Renauld & Cardot) J.-P. Frahm, which differs only by shorter lamellae at the back of the costa. This subspecies occurs in South Africa, Malagasy, Reunion and the Seychelles, conspicuously at about the same latitude as ssp. julaceus, also in the SE part of this continent and even in the same habitats (however, down to sea level).

    Campylopus julaceus has a noticeably broad altitudinal range. Whereas it has been found in SE Brazil not below 700 m, it grows down to 300 m in Paraguay and again up to 3500 m in the Andes of Argentina. The locality in Bolivia is at 700 m, which might be the reason for the continuous range, connecting the Andes with SE Brazil.

    Only male plants, producing conspicuous budlike perichaetia, have been found.

  • Distribution

    On open sandy or gravelly soil along roadsides, rarely on sandstone rocks, from SE Brazil to Paraguay, Argentina and Bolivia, in elevations from 300 m to the forest line.
