Notes     (Last Modified On 12/16/2011)
general taxon notes: Brotherus (1925) recognized three subfamilies in the Hedwigiaceae, including Cleistostomoideae with a single genus Cleistostoma Brid. The generic name is considered to be invalid because it includes the type of Syrrhopodon Schwägr. Cleistostoma sensu Brotherus (1925) was replaced by Bryowijkia Nog. (Noguchi 1973). The genus has since been placed in different families, such as in the Trachypodaceae (Noguchi 1973), Erpodiaceae (Buck & Goffinet 2000), and even back to the Hedwigiaceae (Goffinet et al. 2009). In my opinion, Bryowijkia is distinct from the Hedwigiaceae by its sporophytic features and leaf morphology. For the same reasons, I do not consider it close to the Trachypodaceae. Here, it is treated in its own family, Bryowijkiaceae (Frey & Stech 2008).

蔓枝藓科   man zhi xian ke
by Wang Mei-zhi
 Plants extensively elongate, yellowish green to brown, rather stiff, in large mats, often pendulous. Primary stems creeping or pendulous, to 15–20 cm long; secondary stems densely 2–3-pinnately branched, with branch tips incurved when dry, erect when moist. Stem leaves loose, usually deciduous or reduced as scale-like leaves, ovate-lanceolate, shortly to long-acuminate, often secund; branch leaves dense; erect, oblong-ovate, 1.2–1.6 mm × 0.3–0.6 mm, abruptly acute or apiculate at the apex, usually plicate; margins sometimes recurved below, slightly decurrent at the base; costae extending just above mid-leaf; upper leaf cells narrowly oblong-oval, 17–35 µm × 2.5–7.5 µm, coarsely papillose in rows, rather thick-walled; median cells elongate, 25–60 µm × 2–5 µm, coarsely papillose, occasionally porose; basal marginal cells shortly rectangular, 12–17 µm × 10–12 µm, smooth; alar cells slightly enlarged. Dioicous. Perichaetial leaves oblong-lanceolate; costae ending in the leaf apices; cells sparsely papillose. Setae very short, ca. 1 mm long; capsules globose, immersed, reddish brown, smooth; opercula shortly conic-rostrate; annuli not developed; peristome single with the teeth variously reduced, short, smooth. Calyptrae small. Spores spherical, multicellular, sometimes endosporic, 8–13 µm in diameter, finely or coarsely papillose.
