Ten ways of seeing
- measured cast yellow-green
- slightly upright 1.28 : 1
First Look
夫象物必在于形似，形似须全其骨气。
—— 唐·张彦远《历代名画记》
Likeness is the threshold; bone-and-breath is the point.
Slightly taller than wide; the eye lands above centre. 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 Burgess milkvetch: 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 黄芪属 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 0.2% of foliage, the cast tending yellow-green — as with pale or white blooms, outline and tone do the talking. Wildflowers are rarely tidy: small blooms, slender stems, leaves imperfect and often chewed. That untidiness is exactly what records wind, light and soil.No colour group is recorded. A single plant, laid out with nothing hidden.
Composition
The sheet is slightly tall. No details are appended: a plate for looking, not for keying out. The plant covers only 4% of the sheet, centred below centre; the emptiness is where the eye rests.
Line and Colour
After 1900 photography and colour reproduction ran alongside watercolour: accuracy rose, the cut of the burin disappeared. 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: this is a photomechanical record — match the colours directly, do not imitate the printing grain.
Poetic Resonance
终日白云应自足，明年芳草又何如。
—— 唐·皇甫冉《酬權器》
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 Chinese verse wildflowers bloom unseen, owing nothing to praise; in the West they mark a place — one species, one landscape's character. Meanings change their tune: the same flower can say opposite things within a century.
Season and Place
By latitude and altitude. Native plants of woodland floor, bog, roadside and rock crevice. The year 1925 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
“North American wild flowers” carries only Mary Vaux Walcott'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. The flower of that year is dust, yet its image on paper has outlived every living cousin.
