Lacinia, “a slash. A deep taper-pointed incision” (Lindley); “a slender, elongate lobe” (Fernald 1950); the fine, deep, irregular divisions of a laciniate structure; (in fungi) “a delicate branch of a lichen thallus” (Ainsworth & Bisby); (bryophytes) "segment; appendages coarser than cilia and more than one cell wide” (Magill 1990); the segments of a fern frond may be referred to as laciniae: lacinia,-ae (s.f.I), abl. sg. lacinia, nom. pl. laciniae, dat. & abl. pl. laciniis, 'flap of a garment;' see 'laciniate' below; see incisus,-a,-um (part.A); see edging, flap, pocket; see segment;

NOTE: the segments of a fern frond may be referred to as laciniae.

NOTE: (bryophytes) laciniae = segments, i.e. appendages coarser than cilia and more than one cell wide” (Magill 1990); cilia = (bryology) cilium,-ii (s.n.II), nom. pl. cilia: “delicate, hair-like or thread-like structure mostly one cell wide and unbranched (opposed to lacinia)” (Magill 1990); see cilium,-ii (s.n.II).

- laciniae e basi versus apicem decrescentes; sori impressi, plerumque partem superiorem laciniarum occupantes, segments diminishing from the base to the apex; sori impressed, usually occupying the upper part of the segments.

- laciniae sex, quarum tres exteriores reflexae, tres interiores erectae, segments 6, of which the 3 outer reflexed, 3 inner erect (Stearn).

- foliis sessilibus, calycis usque ad medium fissi laciniis lanceolatis acutiusculis (Boissier), with leaves sessile, split to the middle of the calyx with rather acute, lanceolate laciniae [i.e. irregular divisions].

- calyptra basi in lacinias inaequales obtusas icisa, laciniis inaequaliler incisis.(Mueller), the calyptra at the base deeply cut into unequal slashes [i.e. laciniae], with the laciniae unequally deeply cut.

- corolla bilabiata, labio supero bifido breviore, labii inferí tripartiti lacinia media majore, tubo cylindraceo subincluso intus barbato (F. Mueller), the corolla bilabiate, with the upper lip shortly bifid, larger than the middle lacinia of the tripartite lower lip, with a cylindric, nearly included tube bearded on the inside.

- calyx subglobosus, primum clausus, mox in laciniae 5 sub-2-labiatim connatas ruptus (B&H), calyx nearly globose, at first shut, soon ruptured into 5 laciniae fused nearly as 2-lips.

- nectarium 2-phylIum 1. 2-labiatum. Labium inferius sub lacinia superiore corollae insertum, patens, erectiusculum, integrum 1- 3 - lobum. (Swartz), nectarium 2-leaved, 1-2-lipped. the lower lip inserted under the upper lacinia [i.e. slender, elongate lobe] of the corolla, spreading, nearly erect, entire, 1-3-lobed.

- [Sphaeria] laciniis epidermidis totidem triangulis subaequalibus stellatim fissis ac retroflexis quasi corona cincta (S&A); with the laciniae of the epidermis just as many, triangular, nearly the same, stellately divided and retroflexed girdled like a crown.

NOTE: slash (noun), a long somewhat irregular cut or slit made by slashing, i.e., cutting with strokes lacking careful aim.

NOTE: “Lacineae are margins cut into bits for the sake of decoration, and clippings of the extreme edge. Hence leaves divided into sections by means of sinuses, or separated according to their natural divisions are called lacinate. However there are those who use the term lacinosum for sinuosum” (Fuchs in Choate).
