A Grammatical Dictionary of Botanical Latin

Fimbriae,-arum (pl.f.I), dat. & abl. pl. fimbriis: fringe, border, edge, a bordering fringe, a border resembling a fringe, a border composed of slender processes [> L. fimbriae,-arum pl.f.I) fibers, threads, shreds, fringe];

- lobi calycis fimbriis glanduliferis carentes, the lobes of the calyx lacking glandular fimbriae.

- petala fimbriis destituta (F. Mueller), the petals lacking a bordering fringe.

- [lichen] apothecia pallescentia vel fuscescentia, saepius sat parva, in apicibus fìmbriarum verticillarìum sita; (Nyl.), apothecia rather pale or blackish-brown, more often quite small, situated on the apices or the verticillar fimbriae.

NOTE: this word in classical usage is not used in the singular.

NOTE: the fimbriae seem to be regular, thin processes, unlike the irregular (slashed, ragged) ones of laciniae, q.v., hence their use as a synonym of the peristome teeth around the mouth of the theca in mosses:

Peristome, “the fringe of teeth which surrounds the mouth of the spore-case [i.e. theca or capsule mouth] of an Urn-moss” (Lindley); ”the fringe or its homologue round the orifice of a Moss-capsule” (Jackson).
