Prostanthera Labill. [1]

Latin[edit]

PROSTANTHERA
Calyx post florescentiam clausus, utroque labio integerrimo. Corolla monopetala, ringens; antheris appendiculatis. Baccae quatuor, monospermae.

Etym. προσθειν, appendix, άνθερα, anther, propter antherarum appendicem.

English[edit]

PROSTANTHERA
Calyx closed after flowering, with both lip(s) entire. Corolla a single gaping petal; anthers appendicular. Berries four, single-seeded.

Etym: προσθειν, appendage, άνθερα, anther, because of the anthers’ appendages.

Prostanthera lasianthos[edit]

Latin[edit]

Prostanthera foliis lanceolatis, serratis; paniculis axillaribus terminalibusque; corollis hispidis.

FRUTEX orgyalis et ultra, ramulis patentibus, oppositis, quadrangulis. Folia petiolate, oblonga, utrinque acuta, dentato-serrata, punctis glandulosis numerosisque subtus impressa, opposita. Flores terminales, paniculati axillares vero ut plurimum racemosi, pedicellis iisdem brevioribus. Calyx bracteis linearibus, binis, infra stipatus, bilabiatus, utroque labio integro, obtuso, margine interiori praesertim tomentoso, post florescentiam clausus, labio inferiori supra breviorem superiorem inflexo. Corolla tubo brevi, sensim ampliato, undique pilis rigidis, brevibus inspersa, bilabiata, labio superiori recto, breviori, emarginato, inferiori vero dilatato, trilobo, lobis rotundatis, crenatis, intermedio majori. Stamina quatuor, didynama, per paria sub utroque labio inserta; antheris versatibilus, ellipticis, bilocularibus, bivalvibus, valvula interna subtus, filamento setis quibusdam terminato, appendiculata. Germen superum, quadrilobum; stylus inter lobos, imum versus; stigma bifidum, laciniis aequalibus, obtusis. Semina quatuor, baccata, ovata, intus versus basim, ubi affixa receptaculo, oblique truncata; integumento extimo carnoso, tenui; medio autem fragili, crustaceo, intimoque membranaceo. Corculum oblongum, infra attenuatum, cotyledonibus planiusculis; radicula parva, teretiuscula, infera.

HABITAT in capite Van-Diemen

English[edit]

Prostanthera: with lanceolate serrate leaves; with axillary and terminal panicles; with a hairy corolla.

A SHRUB 1.95 m high and higher, with spreading opposite and square branchlets. Leaves petiolate, oblong, acute at both ends, dentate-serrate and opposite; with numerous glandular points/dots impressed below. Flowers terminal, paniculate, those which are axillary have shorter racemes for the most part, with shorter pedicels. Calyx with linear bracts, paired, crowded below, two-lipped, with both lip(s) entire, obtuse, with the interior margin especially tomentose, closed after flowering, with the lower lip having above it a superior shorter inflexed lip. Corolla with a short tube, gradually widening (increasing), with rigid hairs on all sides, shortly interpenetrated, two-lipped, with the upper lip upright, shorter, emarginate, with the lower lip wide(ned), three-lobed, the lobes rounded, crenate, with the middle lobe being the larger. Stamens four, in two pairs of unequal length (didynamous), with both pairs inserted below the labium; with versatile anthers, elliptical, two-locular, bivalvular, the valve being inward and under, with the filament terminating in appendiculated bristles. Ovary superior, with four lobes; the style (inserted) between the lobes, towards the bottom of the style; stigma bifid, with equal obtusely fringing lacinia. Seeds four, berry-like, ovate, inside towards the base, where they are attached to the receptacle, obliquely truncate; with a fleshy thin outer covering, with, however, a fragile crustaceous centre, and membranous at the heart (deepest). Plumule (the shoot of the embryo) oblong, attenuated below, with cotyledons fairly flat; root small, somewhat terete, below.

(Legend for Figure)

Latin[edit]

1. Flos, bracteis baseos conspicuis.
2. Idem, Corolla sejuncta.
3. Corolla seorsum
4. Eadem, medio labii superioris longitudinaliter fissa, expansa, staminibus conspicuis.
5. Stamen auctum.
6. Semina in calyce bracteato, jam clauso, stylo superstite
7. Eadem, calyce dempto.
8. Semen solutum, auctum, visum postice.
9. Ejusdem sectio tranversalis, intacto perispermo.
10. Ejusdem longitudinalis, with th sectio, cum situ et figura corculi.

OBS: Dignum valdè notatuseminis corculum, in aliis Labiatis caeteroquin nudum, ex contrario in ista crasso obvolutum esse perispermo.

English[edit]

1. Flower, with conspicuous bracts at the base.
2. The same, Corolla separated.
3. Corolla side (oblique?) view
4. The same, in the middle of the upper lip.
5. Stamen enlarged.
6. Seed in the bracteate calyx, now closed, with style above (superstite??)
7. The same, with calyx removed.
8. Seed, unbound, enlarged.
9. Of the same, in tranverse section, with intact perisperm.
10. Of the same, in longitudinal section, with the position and shape of the plumule(??)

OBS: the plumule with its seed is worthy of note. In other Labiatae (Lamiaceae) it is naked, in this, on the contrary, the seed has a thick inverse(ly) rolled up covering.
