A Grammatical Dictionary of Botanical Latin

 
Articulus,-i (s.m.II), abl. sg. articulo, nom.pl. articuli, acc.pl. articulos, dat.& abl.pl. articulis: “a joint; a place where spontaneous or easy separation takes place” (Lindley); an article or joint (Jackson); joint, part between nodes, segments, articulations; “The portion of a fruit (especially in Leguminosae) separated from others by a constriction or joint, as in Desmodium” (Fernald 1950); “a joint or connection between two parts capable of spontaneous separation (as the base of a leafstalk or of the peduncle of a flower; a node or thickened portion of a stem or the interval between two such points” (WIII) [> L. dim. of artus,-us (s.m.IV), the joints, limbs]; see loment;

(in shells) “the hinge including the hinge plate, teeth and ligament in bivalve mollusks” (WIII);

- articuli subquadrati, the articuli almost quadrate.

- articulis interioribus crassioribus, with the interior joints thicker.

- petiolo articulis rubiginosis, petiole with articulations rusty-red.

- leguminis articuli sibi invicem replicati intra calycem retracti (B&H), the joints of the legume alternately turned back [upon themselves, dat.], drawn back inside the calyx.

- articulo inferiore pedicelliformi aspermo, superiore globoso, 1-loculari, 1-spermo (B&H), with the lower joint like a pedicel, seedless, the upper globose, 1-locular,1-seeded.

- radices ramosa; filiformes attenuatae, raro articúlata, a basi articulorum frondis egredientes, roots branched, filiform, attenuated, rarely jointed, coming forth from the base of the joints of the frond.

- fila in fronde juniori omnino confervoidea, areolis singula serie longitudinali dispositis, indivisis et artículos mentientibus, the filaments in the younger frond completely confervoid, with the areoles arranged in a single longitudinal series, undivided and simulating joints.

- in utroque casu sporae morphosi articuli terminalis filorum fructiferorum oriuntur, in the other case, the spores arise, by the development of the terminal joint of the fruiting filaments.

- [algae] articuli, si lente parum augente observatur frons, fere ubique geniculis obscurioribus distinguendi (Agardh), the joints [i.e. articuli], if the frond is examined by magnifying a little with a lens, are almost everywhere to be distinguished from the more indistinct genicula.

NOTE: articuli (pl.m.II): “the segments of coralline Algae, usually incrusted with lime” (Jackson).

NOTE: articuli (pl.m.II), the ‘articles’ or joints in Nostoc, a blue-green alga;

- [Nostoc callidiarum Wood.] in formis duabus occurrentibus:

forma altera parva, viridi, articulis cylindricis, cum cellulis perdurantibus hic illic interjectis, vaginis interdum obsoletis, saepius diffluentibus;

forma altera maxima, articulis globosis vel oblongis, aurantiaco-brunnea, cellulis perdurantibus ab articulis ceteris haud diversis.

Nostoc callidiarum Wood.] occurring in two forms:

one form small, green with cylindrical joints, the [heterocysts] scattered here and there, sometimes with the sheaths sometimes absent, often diffluent [i.e. disappearing];

the other form very large, with the articles globose or oblong, orange-brown, with the [heterocysts] not different from the other cells.

- articulis globosis vel saepius ellipticis, plerumque medio pellucidulis, laxe connexis (Wood), with the joints globose or more often elliptical, mostly in the center somewhat translucent, loosely connected.

- (algae) articulis diametro plerumque aequabilis, ultimis saepe inflatis, vel in spermatoidia obovata transientibus (Braun), with the articles usually equal in diameter, the topmost ones often inflated, or transforming into spermatoidia [i.e. small cells containing gonidia].

 

A work in progress, presently with preliminary A through R, and S, and with S (in part) through Z essentially completed.
