Notes     (Last Modified On 4/3/2009)
general taxon notes:
This species is very close to Pogonatum urnigerum (Hedw.) Beauv., but it has shorter leaves (ca. 4 mm long) and plane, quadrate apical cells of lamellae in contrast to the latter species, which has longer leaves (6–7 mm long) and rounded apical cells of lamellae. The rather large, quadrate, strongly thick-walled, and papillose apical cells of lamellae are characteristic of this species, which are different from other closely related species in the genus, e.g., Pogonatum inflexum (Lindb.) Sande Lac. and Pogonatum neesii (C. Müll.) Dozy.
