Byttneria dentata (1827)
Ten ways of seeing
- measured cast yellow-green
- upright 1.61 : 1
First Look
搜尽奇峰打草稿。
—— 清·石涛《苦瓜和尚画语录》
Exhaust the strange peaks, and then make the sketch.
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 Byttneria dentata: the first word is the genus it belongs among, the second the epithet that sets it apart. Here the epithet dentata means “toothed” — the name records the feature the namer noticed first. The Chinese name 锦葵科 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour covers 1.6% of the sheet, foliage 10.1%, the cast yellow-green. 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. 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 22% of the sheet, centred a little right 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. 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
十年结子知谁在，自向庭中种荔枝。
—— 唐·白居易《種荔枝》
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. Flower language was added later; the flower knows nothing of it, and that innocence is part of its power.
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. The image is public domain; the hand-colouring is still one person's hand.
What to Take Away
Appreciation is not knowledge but habit — one more look each time. Two centuries on, the plant may still flower in some garden; the one on this sheet stopped in the season of 1827.
