. Genus 14. BLEPHAROSTOMA, Dumort. 



Involucre many-leaved, everywhere imbri- 

 cate, perichaetial leaves articulate-ciliate. Peri- 

 anth sessile, erect, terete, ovoid, naked, mouth 

 clad with long articulate cilia. Capsule four- 

 valved, coriaceous, naked. Elaters double, 

 naked, deciduous. — Dumort. Rev. Jung. p. 18. 



(1835-) 



Plants delicate, without stipules, leaves transvers- 

 ally or vertically plane, or parted nearly to the 

 base, segments setaceous. 



" Blepharostoma, although at first sight so dif- 

 ferent from Cephalozia in the quadripartite leaves, 

 with filiform crura, has the involucre and perianth 

 formed on the same plan, the bracts being tri- 

 stichous and mostly trijugous, and the perianth, 

 when young, distinctly trigonous (with the third 

 angle postical), although at maturity it becomes 

 nearly terete, and is trigonous only at the many- 

 ciliated apex. The dichotomous ramification, 

 without a single postical branch, and the con- 

 stantly terminal female flowers separate it from 

 Cephalozia and assimilate it to Pleuroclada." — 

 Spruce on Cephalozia, p. 16. 



Blepharostoma trichophylla, Linn. 



Stem creeping, branched, leaves everywhere 

 imbricate, three-parted nearly to the base, 

 setaceous, nearly erect, articulate, perichaetial
