Notes     (Last Modified On 3/20/2009)
general taxon notes:
 
The long-cuspidate leaf apices of this species are distinctive in the field and provide an easily observed character. Nevertheless, confusion with D. collenchymatosum exists. The latter species, however, has a shorter leaf apical acumen, a weaker leaf border, and ironically, larger, but not distinctively collenchymatous leaf cells. Without sporophytes, Distichophyllumcuspidatum may be mistaken for Daltonia aristifolia, which has similar, long-cuspidate leaf apices. However, the leaf apices of Daltonia aristifolia are gradually narrowed into a long acumen, while those of Distichophyllumcuspidatum are contracted into a long acumen. The leaf cells of Daltonia aristifolia are irregularly rhomboidal to shortly polygonal, while those of Distichophyllumcuspidatum are uniformly round-hexagonal.

4. Distichophyllum cuspidatum (Dozy & Molk.) Dozy & Molk. 尖叶黄藓 jian-ye huang xian
Musci Frond. Ined. Archip. Ind. 4: 101. 1846. Hookeria cuspidata Dozy & Molk., Ann. Sci. Nat., Bot., ser. 3, 2: 305. 1844. Type. Indonesia: Java.
 
Plants forming aggregate tufts. Stems ascending, 1.0–1.5 cm tall, 4 mm wide with leaves. Leaves erect, moderately crisped, often twisted when dry, not complanate, oblong to broadly lingulate, at times oblanceolate, 3–4 mm × 1 mm, concave above, the leaf apices more or less contracted into long-cuspidate acumens; leaf acumina variable in length, 150–300 µm long; leaf borders strong, consisting of 2–3(–5) rows of thick-walled, linear cells; leaf margins entire, plane above, revolute below, at times undulate; costae reaching more than 2/3 the leaf length; leaf cells nearly uniform above, round-hexagonal, 18–40 µm, often collenchymatous, becoming shortly rectangular at base, 34–56 µm × 14–20 µm. Perichaetial leaves very small, about 1 mm long. Sporophytes lateral; setae mostly smooth, becoming papillose distally, ca 5 mm long; capsules shortly ovoid, erect or inclined.
