Notes     (Last Modified On 5/5/2009)
general taxon notes:
Symphyodon echinatus appears to be closely related to S. imbricatifolius (Mitt.) S. P. Churchill from Central and South America, but it differs from the latter in having strongly dimorphic stem and branch leaves, distinctly decurrent stem leaves, shorter and strongly prorate leaf cells, and longer and stronger double costae. The presence of brood bodies is also a distinguishing feature of S. echinatus.

1. Symphyodon echinatus (Mitt.) Jaeg. 异叶刺果藓 yi-ye ci-guo xian
Ber. Thätigk. St. Gallischen Naturwiss. Ges. 1876–77: 296. 1878. Stereodon echinatus Mitt., J. Proc. Linn. Soc., Bot., Suppl. 1: 110. 1859. Type. India: Sikkim, Hooker 734 (holotype NY; isotypes BM, S, W).
 
Plants medium-sized, to 3 cm long, yellowish green to brownish green, not glossy. Stems with somewhat dendroid shoots bearing many bipinnate to tripinnate branchlets. Leaves appressed, clearly dimorphic; stem leaves ovate-lanceolate, 1.3–1.4 mm × 0.5–0.6 mm, symmetric, gradually tapered, narrowly acuminate at the apex; margins irregularly serrate above, serrulate or subentire below, often clearly decurrent at the base; branch leaves 0.7–0.9 mm × 0.30–0.40 mm wide, slightly incurved on one side or on both sides, oval, broadly ovate to oblong-ovate, cordate or oblong-lanceolate; all leaf apices broadly to moderately broad acute; margins irregularly serrate in the upper 2/3, serration formed by a row of enlarged cells, subentire below; costae unequal, extending to 2/5–1/2 total leaf length; apical leaf cells not particularly shorter than the adjacent cells; median cells linear, 30–40 µm × 2.5–3.5 µm, strongly prorate at the upper ends, especially in branch leaves; alar cells differentiated, quadrate to rectangular, thick-walled, of 2–4 rows extending 2–4 cells up the margins. Perichaetial leaves sheathing at the base, abruptly narrowed to a long acumen, cells thick-walled, porose, costae very short, double. Sporophytes not seen.
