9. Syrrhopodon japonicus (Besch.) Broth., Nat. Pflanzenfam., ed. 2. 10:233. 1924; Calymperes japonicum Besch., J. Bot. (Morot) 12: 296. 1898.


Syrrhopodon lonchophyllus Dix., Hong Kong Naturalist, Suppl. 2: 8. 1933. Type. China: Hong Kong, New Territories, Ma on Shan (Mt.), 6th Apr. 1931, Herklotts 371 (holotype BM).

Plants robust, wiry, 3–4 cm high, green to brownish green, in dense springy cushions. Stems elongate, rhizoids brown. Leaves curled-secund to nearly straight when dry, straight when wet, long-linear-acuminate above broader base, 5–10 mm long, axillary hairs inconspicuous; cells of upper laminae obscure, isodiametric to rectangular, smooth or occasionally with low remote papillae abaxially, bulging to mammillose-papillose adaxially; margins of upper laminae thickened and toothed in two rows, teeth paired, margins of lower laminae irregularly toothed at shoulders, the teeth sometimes sharp and spreading as in S. gardneri; cancellinae mostly ending in broad angles distally, their distal cells merging gradually with adjacent green cells of upper laminae. Gemmae frequent but inconspicuous, adaxial on tip of costa. Sporophytes not seen.

Type. Japan: Nagasaki, Faurie 15454 (isotype H).

Habitat: common and often abundant on tree trunks and bases, decaying logs, rock, and soil in forests at moderate to high elevations at 520–2300 m; Distribution: China, Korea, Japan, India, Malaysia, and western Oceania.

Plants of S. japonicus may closely resemble those of S. gardneri at first glance, and the two species are often confused in identification. The two species may occur together in the same habitat and share the same substrate, as in Iwatsuki et al. 1263, cited above, in which both species occur. They differ consistently as noted in the discussion for S. gardneri. Syrrhopodon japonicus has previously been reported from China as Syrrhopodon konoi Card., a synonym.
