Notes     (Last Modified On 5/5/2009)
general taxon notes:
Eurhynchium arbuscula is characterized by its dendroid plants and its broadly decurrent leaf bases. It has been treated as a species of Kindbergia (Ochyra 1982) or Stokesiella (Robinson 1967). It is treated here in the genus Eurhynchium, because it shares many features of the latter.

Plants large, pale green to dark green. Stems stout, dendroid, sparsely foliate, densely bi- to tri-pinnately branched. Stem and branch leaves sharply differentiated; stem leaves smaller, broadly ovate to semi-orbicular, 1.26–1.44 mm × 0.9–1.13 mm, shortly acute or apiculate at apex, somewhat plicate; margins serrulate, slightly recurved at base; costae slender, ending well below leaf apex; median leaf cells rhomboidal, 20–37 µm × 5–7 µm, with rounded ends; basal cells numerous, hyaline, lax, rounded-quadrate to hexagonal, in a distinct group; branch leaves usually triangularly ovate-lanceolate, 0.95–0.99 mm × 0.63–0.72 mm, abruptly, slenderly acuminate at apex, broadly decurrent at base, widest at insertion; margins serrulate; costae ending near leaf apex, projecting at tips; median leaf cells 20–25 µm × 6–7 µm. Dioicous. Perichaetial leaves lanceolate, ecostate. Setae 25–30 mm long, roughened, blackish when old; capsules horizontal, ovoid, constricted at neck; opercula long-rostrate; exostome teeth linear-lanceolate; endostome segments as long as teeth, perforate; basal membrane high, ca. 1/2 the segment height; cilia 2–3, nodulose. Spores 12–15 µm in diameter, smooth.
