Ten ways of seeing
- measured cast yellow-green
- upright 1.65 : 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.
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
Only the genus Cactus is given; species-level names came later. No established Chinese name exists, so it is cited by its binomial alone.
Form and Colour
Measured on this plate: flower colour covers 7.5% of the sheet, foliage 5.2%, 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.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 takes about 32% of the sheet, centred below centre — the easy measure most florists kept to.
Line and Colour
The first half of the nineteenth century moved from copper to steel to lithography; stipple could render the softest transition. There is evidence on the back too: the plate mark pressed into the paper, the slight relief of the pigment, lines worn shallow in a later printing. 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
山城过雨百花尽，榕叶满庭莺乱啼。
—— 唐·柳宗元《柳州二月榕葉落盡偶題》
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. In a flora it is a species first and a symbol second; the order is worth keeping.
Season and Place
flowering follows the first rains, so a month on the plate often means 'after the rain'. 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 1829 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
“Edwards' Botanical Register” carries only Sydenham Edwards, John Lindley'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. Two centuries on, the plant may still flower in some garden; the one on this sheet stopped in the season of 1829.
