Notes     (Last Modified On 5/5/2009)
general taxon notes:
Its broadly spathulate leaves are reminiscent of a small form of Distichophyllum mittenii. In contrast, D. wanianum has strong and thick leaf borders without submarginal rows of smaller cells. Its closest affinity is with the two varieties of D. oblongum, the other Chinese endemics in the same region from Guizhou.

Plants small, mat-forming. Stems up to 1.6 cm tall, 2 mm wide with leaves. Leaves strongly crisped or cirrate when dry, broadly spathulate with a long narrow basal part when wet, 2.0–2.5 mm × 1.0–1.2 mm, the leaf apices broadly rounded, at times with a minute mucro; leaf margins plane, wavy in the upper half even when wet, with strong borders all around; the border about 10–15 µm wide, consisting of 2–3 rows of thick-walled, linear cells, but becoming one row around the leaf apex; costa single, reaching near the apex; laminal cells nearly homogeneously small, quadrate-polygonal, 11–13(–18) µm wide, becoming smaller (9–13 µm wide) apically and rectangular [33–45(–67) × 11–22 µm] basally. Perichaetial leaves small, oblong-spathulate, distinctly mucronate, with costa well developed. Sporophytes lateral; setae 5–10 mm long, smooth below, gradually becoming weakly papillose distally; capsules oblong-ovoid, 2 mm long.
