Hookeriaceae

Daltonia angustifolia, from here.

Belongs within: Hookeriales.

The Hookeriaceae are a family of predominantly tropical mosses. Hookeriaceae are distinguished from other families of Hookeriales by the presence of a central strand in the stem. The circumscription of the Hookeriaceae, however, has varied between authors, with Daltonia and related genera potentially separated as the Daltoniaceae. Genera of the Hookeriaceae include Distichophyllum, characterised by dimorphic leaves with a single costa.

Characters (from Smith & Smith 2004): Stems with central strand. Pseudoparaphyllia filamentous or absent. Rhizoids unbranched. Leaves more or less complanate, often asymmetrical, often bordered; costa short and double or absent; cells large, lax, alar cells undifferentiated. Setae smooth or spinose; capsules inclined to pendulous; stomata usually superficially; lid conical; exostome teeth horizontally striate, endostome with high basal membrane, processes keeled, finely papillose, cilia sometimes present; calyptrae multistratose at middle, glabrous.
