Notes     (Last Modified On 5/5/2009)
general taxon notes:


Distichophyllum elmeri has been unjustifiably considered to be a synonym of D. cirratum by Mohamed and Robinson (1991). Our study of the Chinese specimens reveals that these two species are not alike morphologically and can be separated using microscopic characters. Sometimes, usual forms of this species might be difficult to distinguish from D. cirratum. Following Noguchi and Iwatsuki (1972), we recognize D. elmeri, but consider it to be a variety of D. cirratum.

Harvard pap. Bot. 7: 36. 1995. Distichophyllum nigricaule Bosch & Sande Lac. var. elmeri (Broth.) Tan & Robinson, Smithsonian Contr. Bot. 75: 22. 1990. Distichophyllum elmeri Broth., Leafl. Philipp. Bot. 2: 656. 1909. Type. The Philippines: Luzon, Baguio, Elmer 10453 (holotype H).
Plants are similar to var. cirratum in habit, size, and leaf shape. The submarginal leaf cells [14–18(–23) µm wide] of the present variety are smaller than the paracostal cells [23–36(–52) µm wide]. In addition, there are up to 8 rows of small, submarginal leaf cells in var. elmeri. The leaf borders of var. elmeri are as broad as in var. cirratum, consisting of 3–4 rows of linear cells. The leaf apices of var. elmeri are muticous or shortly mucronate (5–10 µm long) and the costae never reach the leaf apices. Setae are 10–12 mm long, yellowish brown, smooth, becoming coarsely wrinkled near the bases of capsules.
