Manihot pruinosa (1827)
Ten ways of seeing
- measured cast yellow-green
- upright 1.63 : 1
First Look
论画以形似，见与儿童邻。
—— 宋·苏轼《书鄢陵王主簿所画折枝》
To judge painting by likeness alone is the view of a child.
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 the darkest small patch: the whole tonal order is measured from there.
Name and Thing
The binomial is Manihot pruinosa: 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 木薯族 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour is sparing, 0.9% of the sheet against 14.0% of foliage, the cast tending yellow-green — as with pale or white blooms, outline and tone do the talking. Tropical plants defy temperate habits: heavy, saturated flowers with strong scent, leathery or dissected leaves, stems that climb, swell, or reduce to spines.No colour group is recorded. Three things fix the habit: leaf arrangement, tepal count, and how the flower is borne.
Composition
The sheet is tall. No details are appended: a plate for looking, not for keying out. The plant covers only 21% of the sheet, centred below centre; the emptiness is where the eye rests.
Line and Colour
The first half of the nineteenth century moved from copper to steel to lithography; stipple could render the softest transition. Decide first whether it was printed or painted; only then discuss whether it is beautiful. 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
海客谈瀛洲，烟涛微茫信难求。
—— 唐·李白《梦游天姥吟留别》
Seafarers talk of Yingzhou, lost in mist and waves, truly hard to find.
The poem gives the mood first and the picture supplies the form; set the line beside the plate and 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. 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 1827 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
“Plantarum Brasiliae icones et descriptiones hactenus ineditae” carries only Johann Baptist Emanuel Pohl'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
Carry three rules away: whole before detail; line before colour; picture before book. Two centuries on, the plant may still flower in some garden; the one on this sheet stopped in the season of 1827.
