Euphorbia nudiflora
Ten ways of seeing
- measured cast yellow-green
- upright 1.72 : 1
First Look
真山水之川谷，远望之以取其势，近看之以取其质。
—— 宋·郭熙《林泉高致·山水训》
Mountains and valleys: from afar take their momentum, up close take their texture — the two distances from which any picture is read.
The sheet is vertical: the eye climbs and settles in the upper half. Let the plant stand before you look for detail. 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.
Name and Thing
The binomial is Euphorbia nudiflora: 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 金虎尾目 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour covers 21.6% of the sheet, foliage 0.0%, the cast yellow-green with a second note of amber. No other plate shares exactly this measure. Tropical plants defy temperate habits: heavy, saturated flowers with strong scent, leathery or dissected leaves, stems that climb, swell, or reduce to spines. Filed under yellow — a honey-yellow, built in washes from a pale ground. A single plant, laid out with nothing hidden.
Composition
The sheet is tall. No details are appended: a plate for looking, not for keying out. The plant covers only 22% of the sheet, centred near the 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. Take a loupe to three places: petal edge, leaf vein, caption. An unbroken line means engraving; colour crossing the outline means a hand. 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
对织芭蕉雪毳新，长缝双袖窄裁身。
—— 唐·王建《花褐裘》
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
In China these plants carry no classical symbolism; their meaning is newness — new worlds, new species, new trade routes. They show natural history's expanding edge. 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
The tropics have no four seasons, only wet and dry. Central and South America, Southeast Asia, India, Ceylon. Eighteenth- and nineteenth-century artists either sailed with the ships or drew from living specimens under glass. The year 1781 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. See this kind of plate in the flowering season if you can: once you have met the living flower, you stop reading only colour.
The Book and the Hand
“Icones Plantarum Rariorum” carries only Nikolaus Joseph Freiherr von Jacquin's name. From drawing to plate the sheet passed through several hands — the engraver aimed at accuracy, the colourist at speed, and between them lies each plate's unevenness.
What to Take Away
Carry three rules away: whole before detail; line before colour; picture before book. 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.
