A Grammatical Dictionary of Botanical Latin

Peduncle, the stalk of a solitary flower or of an inflorescence (the pedicel, q.v., is the stalk of a single flower within an inflorescence, or also it is of a single flower in the spikelet of a grass); also once used of the seta in mosses (Mitten 1869) and hepaticae; “a primary flower-stalk, supporting either a cluster or a solitary flower” (Fernald 1950): pedunculus,-i (s.m.II), acc. sg. pedunculum, dat. & abl. sg. pedunculo, nom. pl. pedunculi, acc.pl. pedunculos, dat. & abl. pl. pedunculis [> L. pes, gen.sg. pedis (s.m.III) foot];

- pedunculis capillaribus, floribus multo minoribus duplo longius pedicellatis (Boissier), with the peduncles thread-like, with the flowers much smaller, two times longer pedicellate [i.e. with the pedicels two times longer than the peduncles].

- pedunculus elongatus terminalis glaber, peduncle elongated terminal glabrous.

- pedunculi terminales et exillares nudi glabri uniflori, peduncles terminal and axillary naked (i.e. without bracts) glabrous one-flowered.

- pedunculis patentibus, inferioribus silicula duplo saltem longioribus, with peduncles spreading, the lower at least twice longer than the silicle; cf. scape (Stearn).

- pedunculis folio dimidio brevioribus (DeCandolle), with the peduncles shorter than the leaf halved.

- pedunculis 3-fidis 3-floris seu ternis 1-floris (DeCandolle), with the peduncles thrice divided [i.e. to the outer half] 3-flowered, or in threes, one-flowered.

- pedunculis paucifloris folio longioribus (DeCandolle), with the peduncles few-flowered, longer than the leaf.

- pedunculis multifloris folii longitudine (DeCandolle), with the peduncles many-flowered, with the length of the leaf.

- pedunculo longo tenuissimo versus basin parcissime piloso, with the peduncle (seta) long, very slender, toward the base very sparingly pilose.

- pedunculis longioribus differt, it differs by the longer peduncles.

- pedunculis 1--3-radiatis, with peduncles 1-3-radiate.

- corticem trunci ramorumque , petiolos , pedunculos, calyces — foliis paene praefert in Rosae variis speciebus parasitica : a nobis in R. Eglanteria, canina et centifolia hactenus lecta (S&A), it almost prefers the bark of [tree] trunk and branches, the petioles, peduncles, calyces to the leaves, parasitic on various species of Rosa, to now collected by us on R. eglanteria, canina and centifolia.

- floribus tripligenitis (i.e. 3 floribus per pedunculum), with flowers triple-born (that is with 3 flowers per peduncle). TO DO triple

NOTE: the pedicel, q.v., is “a peduncle of a second or higher order, as in the raceme where the principal flower-stalk is the peduncle, and the lateral secondary ones are pedicels” (Lindley).

NOTE: in the older bryophyte literature, the peduncle (pedunculus,-i (s.m.II) = the ‘fruit-stalk,’ or seta; also in liverworts that develop capsules, it is the ‘peduncle’ or seta, the stalk that supports the capsule;

- PEDVNCVLVS dilute viridis, circa maturitatem in fuscellum vergens colorem (Hedw.), et valde tortilis, tempestate sicca; hinc hygrometricus (Hedw.), the pedunculus [i.e. the seta] is a diluted green, around maturity approaching a light fuscous color, and strongly twisting in dry weather, hence hygrometric.

- pedunculus ad 10 mm longus, validus, in sectione compresso ellipticus, apice paleis hyalinis longe filiformibus sparsim barbatus (Steph.), the seta to 10 mm long, strong, in section compressed-elliptic, at the apex, sparsely bearded with hyaline, long-filiform scales.

- pedunculo e fundo apicali costae orto (Steph.), with the seta arisen from the apical base of the costa

- pedunculus carpocephali validus, ad 2 cm. longus, nudus, apice paleis ovato-oblognis varie laceratis purpureis barbatus (Steph.), the seta of the carpocephalum strong, to 2 cm. long, naked, at the apex bearded with ovate-oblong, variously lacerate purple scales.

“pedicellus, pediculus, pedunculus, pes, petiolus: “the stipe of certain Fungals” (Lindley).

uniparus,-a,-um (adj.A), uniparous, “(obsol.) having but one peduncle” (Lindley).
