Notes     (Last Modified On 5/6/2009)
general taxon notes:
Homomallium incurvatum is similar to H. japonico-adnatum, but differs in having usually falcate-secund leaves, nearly entire leaf margins, smooth and longer leaf cells (40–60 µm), and fewer alar cells (8–15) extending along the margins. In contrast, Homomallium japonico-adnatum has erect, rarely falcate-secund leaves, serrulate leaf margins, often prorate and shorter leaf cells (30–50 µm), numerous alar cells (15–25) extending along the margins.

Plants slender, green, yellowish green or dark green, somewhat glossy. Stems creeping, with rhizoids at base, irregularly or subpinnately branched; branches ca. 5 cm long, usually curved, sometimes with flagelliform branches at the tips.

Autoicous. Inner perichaetial leaves oblong to ovate-lanceolate, long-acuminate, slightly plicate, costae indistinct. Setae 1.2–2.0 cm long, yellowish brown or reddish brown; capsules horizontal, 1.5–1.8 mm × 0.7–0.8 mm, curved; perfect double peristome, with 1–3 cilia.
