Begonia dichotoma
Ten ways of seeing
- measured cast yellow-green
- square 0.87 : 1
First Look
六法者何？一、气韵生动是也；二、骨法用笔是也；三、应物象形是也；四、随类赋彩是也；五、经营位置是也；六、传移模写是也。
—— 南齐·谢赫《古画品录》
The six laws: spirit resonance alive; bone-method in the brush; matching form; colour by kind; planning the placing; copying the masters.
Nearly square, plant and detail each holding a corner. Then step in close: watch where colour meets line, and whether the line ever breaks. Third, find where the yellow is deepest: the whole tonal order is measured from that patch. The pose leans right: the upper half carries 8 points further right than the lower — a living thing, not a diagram.
Name and Thing
The binomial is Begonia dichotoma: the first word is the genus it belongs among, the second the epithet that sets it apart. Two words carry a whole provenance. The Chinese name 葫芦目 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour covers 21.2% of the sheet, foliage 0.0%, the cast yellow-green. No other plate shares exactly this measure. Garden annuals and low perennials: many small, brilliantly coloured flowers to a stem, with leaves palmately lobed, pinnate or entire — the mainstay of the Victorian bedding scheme. Filed under yellow — a honey-yellow, built in washes from a pale ground. Three things fix the habit: leaf arrangement, tepal count, and how the flower is borne.
Composition
The sheet is square. No details are appended: a plate for looking, not for keying out. The plant covers only 27% of the sheet, centred below centre; the emptiness is where the eye rests.
Line and Colour
Eighteenth-century plates are mostly copper engraving: hatched lines for shadow, then hand-colouring by another hand. Craft leaves franker evidence than inscriptions. If you mean to copy it: take its skeleton, its margins and the order of its colours; the burin's hatching is the language of copper — suggest it with pencil density, do not imitate it stroke for stroke.
Poetic Resonance
不嫌野外无供给，乘兴还来看药栏。
—— 唐·杜甫《有客》
The poem gives the mood first and the picture supplies the form; set the line beside the plate and the yellow the corolla becomes its resting point.
Symbolism
Bedding plants carry no imperial weight; they mean the everyday — window sill, border, festival, gift. Victorian floriography grew up among exactly these flowers. This plate leans yellow, which in flower language adds one more degree of feeling. Meanings change their tune: the same flower can say opposite things within a century.
Season and Place
under glass they could be had from March. Gathered from everywhere by plant hunters and the glasshouse trade: pelargoniums from South Africa, campanulas from European mountains, lobelias from North America, fuchsias from Chile. The year 1781 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. The bud and the ripe fruit on one branch tell the season; the name in the title often tells the journey.
The Book and the Hand
“Icones Plantarum Rariorum” carries only Nikolaus Joseph Freiherr von Jacquin's name. A plate is collective work: drawer, engraver and colourist were different hands, and the unnamed ones decided how good it looks.
What to Take Away
Next time you stand before a flowering plant, give it three minutes: leaf arrangement, direction of the flower, the darkest patch. A flora exists to be consulted; look long enough and you forget to consult — someone in 1781 gave a whole day to a single flower.
