Description
Genus Description - Plants small to robust, to 15 cm tall; stems sparsely branched, often densely tomentose. Leaves lanceolate, erect to erect-spreading, straight to falcate, mostly acuminate, apex hyaline or concolorous; margins mostly entire below but toothed at apex; costa strong, filling 1/3-7/8 the leaf width at base, percurrent to long-excurrent, smooth to lamellate at back, in cross-section with ventral hyalocysts and dorsal stereids or two stereid bands; laminal cells quadrate, rectangular or elongate, the basal laminal cells often differentiated; alar cells usually differentiated, inflated to auriculate. Dioicous. Setae elongate, flexuose when dry, cygneous when moist; capsules erect to arcuate, sometimes strumose; peristome teeth deeply divided, horizontally pitted-striate below, papillose above. Campylopus is a large and often taxonomically difficult genus. Many of the species are best determined by a combination of laminal cell characters and costa cross-sectional features. Only two species have species has been found in central French Guiana. Additional species may identified using Frahm (1991) or Allen (1994).
