Revision as of 16:54, 18 September 2019
Plants fairly large to robust, coarse and rigid, yellowish, olivaceous or brownish in the upper part. Stems often more than 10 cm long. Leaves lanceolate; margins recurved on both sides to 1/3–1/2(–3/4) of the leaf length, 1-stratose; long pilose, awns erect-recurved to squarrose, flattened, distantly sharply denticulate at the margins, distinctly decurrent; costa predominantly 3-stratose basally; alar cells undifferentiated; basal marginal border absent or present. Inner perichaetial leaves strongly modified, yellowish hyaline, chlorophyllose distally, sometimes with a short hyaline hair-point. Capsule peristome teeth without a basal membrane.
Distribution
nw North America, e Asia (China, Japan, Korea, Russian Far East, Taiwan).
Discussion
Species 2 (1 in the flora).
The strongly modified innermost perichaetial bracts with thick-walled, chlorophyllose distal portion and sometimes also with a short hyaline hair-point, as well as not flexuose and distinctly erect-recurved to squarrose hyaline leaf hair-points are diagnostic for sect. Lawtonia. Apart from Bucklandiella lawtoniae, it contains only B. laeta, a closely related East Asian counterpart of the American species.
