Diplusodon lanceolatus (1827)
Ten ways of seeing
- measured cast amber
- upright 1.67 : 1
First Look
凡画山水，意在笔先。
—— 唐·王维《山水论》
In painting, the intention precedes the brush.
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. The pose leans right: the upper half carries 9 points further right than the lower — a living thing, not a diagram.
Name and Thing
The binomial is Diplusodon lanceolatus: 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 莲薇属 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour covers 2.8% of the sheet, foliage 9.7%, the cast amber with a second note of crimson. 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.No colour group is recorded. Read the outline, then the colour layers, then the brush.
Composition
The sheet is tall. No details are appended: a plate for looking, not for keying out. The plant covers only 14% of the sheet, centred a little left of 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
一夜不眠孤客耳，主人窗外有芭蕉。
—— 唐·杜牧《雨》
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. Read the locality and the flowering season both with a discount: one is hearsay, the other a ten-day peak.
The Book and the Hand
“Plantarum Brasiliae icones et descriptiones hactenus ineditae” carries only Johann Baptist Emanuel Pohl'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
Next time you stand before a flowering plant, give it three minutes: leaf arrangement, direction of the flower, the darkest patch. The flower of that year is dust, yet its image on paper has outlived every living cousin.
