--><p>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.</p>
