lacinian.

Brit.

/ləˈsɪnɪə/, U.S.

/ləˈsɪniə/

Inflections: Plural laciniae, lacinias, (irregular) lacinia.

Origin: A borrowing from Latin. Etymon: Latin lacinia.

Etymology: < classical Latin lacinia edge of a garment, fringe, hem, strip of cloth, appendage, protuberance, border, in post-classical Latin and scientific Latin also part between the clefts of a leaf, petal, etc. (1660 or earlier), apex of the maxilla (early 19th cent.), probably a derivative (with uncertain suffixation) of lacer mangled, torn (see lacerate v.).In plural form lacinia after the plurals of Latin neuter nouns in -ium, probably reflecting reanalysis of the singular as a plural.

1. Chiefly Botany. A segment or lobe, typically narrow and irregularly shaped, forming part of the margin of a leaf, petal, lichen thallus, etc.; (also) the cleft between two such segments (rare).

1668 Bp. J. Wilkins Ess. Real Char. ii. iv. 105 Of a rough nervous leaf; either that which bears one flower upon a stalk which is bigger, being divided into five laciniæ: or that which bears a less flower, many together at the top of the stalk.

1693 Philos. Trans. (Royal Soc.) 17 762 The Flowers come out in Clusters, are monopetalose, with five Laciniæ or Incisures, all reflected.

1699 Philos. Trans. (Royal Soc.) 21 65 Those [Alceæ] of the first Kind agree in their principal Parts with Mallows,..only their Stalks and Leaves are sometimes more rough, and these divided into narrower and deeper Laciniæ or Jags.

1754 tr. C. Alston Diss. Bot. 114 Without an accurate examination of it [sc. the flower-leaf] at the bottom, it is sometimes much divided into laciniæ or jags, and so apparently consists of several petala.

1760 J. Lee Introd. Bot. i. xii. 27 The Variations of the Corolla in respect to Number concern either Petals, or Laciniæ, Segments.

1830 J. Lindley Introd. Nat. Syst. Bot. 190 Five nerves..continued through the axes of the laciniæ.

1861 W. Mudd Man. Brit. Lichens 1 These lobes [of the foliaceous thallus] sometimes become again subdivided into smaller lobes (lobules, laciniæ), which generally overlap each other.

1889 E. Linton in Rep. Commissioner 1886 (U.S. Comm. Fish & Fisheries) 462 The bothria [of Spongiobothrium variabile] are pediceled and on their outer faces and borders are broken up into a number of delicate frill-like laciniæ.

1942 Bull. Torrey Bot. Club 69 445 Styles..somewhat irregularly 2–3 times cleft, the stylar laciniae forming together a closely matted and involute cluster.

1954 Proc. Helminthol. Soc. Washington 21 107 My specimens resemble those of Linton except that the bothridia are sessile and there are no laciniae.

1978 Flora Neotropica 19 51 Glands 2-3-lobed,..in some cases with short laciniae on the lobes.

2007 Systematic Bot. 32 745/1 Calyx [of Leandra hemogenesii] with the tube..clearly segmented, the lacinias persistent, erect.

2. Entomology. In an insect's mouthparts: a component sclerite of each maxilla, which (in many insects) takes the form of a hardened blade that serves to manipulate and cut up food in the mouth.

1930 A. M. Marshall et al. Junior Course Pract. Zool. (ed. 11) x. 177 The inner division, or lacinia, is a hard blade pointed at the end, and provided with stiff setæ along its inner border.

1960 D. C. Braungart & R. Buddeke Introd. Animal Biol. (ed. 5) xii. 168 Each maxilla terminates in three distinct parts..: a five-jointed palpus or ‘feeler’, a spoon-shaped lip, the galea, and a small chitinized tooth, the lacinia, that terminates in three sharp points.
