Notes     (Last Modified On 5/4/2009)
general taxon notes:
Jaffueliobryum wrightii is a xerophilous moss and mostly characterized by its broadly ovate leaves with a long, hyaline point and hyaline border in 3–4 rows of cells. This species shows a great variation in leaf shape, length of hyaline hair-points, and upper marginal and basal leaf cells. The Chinese specimens usually exhibit relatively shorter hair-points and longer leaves than the specimens from other countries.

Plants small to usually medium-sized, 0.5–2.0 cm high, yellowish green above, brownish below, in dense cushions. Stems erect, moderately branched, subjulaceous, with a well developed central strand in cross section. Leaves thin, somewhat hyaline, particularly at margins, densely imbricate when dry, erect-spreading when moist, broadly ovate to obovate, somewhat concave, 0.5–0.9 mm × 0.4–0.6 mm, abruptly narrowed from an ovate base to rounded-obtuse apex, often ending with hair-points shorter than lamina length; margins plane throughout; costa single, strong, excurrent in a long awn; upper leaf cells irregularly quadrate to rounded-hexagonal, 8–12 µm × 6–8 µm, chlrophyllose, thick-walled, 3–4 rows of cells near margins irregularly rectangular, hyaline, 15–18 µm × 6–8 µm, thin-walled; basal cells short-rectangular to rectangular, 15–28 µm × 11–16 µm, somewhat hyaline, thin-walled. Autoicous. Perichaetial leaves much larger than upper stem leaves. Setae straight, ca. 0.3 mm long, shorter than the capsule urn; capsules erect, immersed, brownish, ovoid, wide-mouthed, ca. 0.8 mm long; annuli differentiated, consisting of thick-walled cells; opercula conic, with short, obtuse beaks; peristome teeth lanceolate, irregularly divided above, perforate below, densely papillose throughout. Calyptrae large, campanulate, covering most of the capsule, longitudinally plicate, deeply lobed at base. Spores spherical, 7–9 µm in diameter, finely granulose.
