First Look
江馆清秋，晨起看竹，烟光日影露气，皆浮动于疏枝密叶之间。
—— 清·郑板桥《题画竹》
On an autumn morning at the river lodge I looked at the bamboo: mist, sunlight, dew, all drifting among the sparse and dense leaves.
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 Psoralea phymatodes: 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 羊豆茶属 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour covers 10.0% of the sheet, foliage 0.0%, the cast yellow-green. No other plate shares exactly this measure. A botanical plate: one plant lifted from field or glasshouse and set at the centre of the sheet, root, stem, leaf, flower and fruit in turn, made legible, citable, transmissible.No colour group is recorded. Read the outline, then the colour layers, then the brush.
Composition
Tall and narrow, the plant rising in one movement with generous margins — the upright format of most floras. (about 1.79 : 1) No details are appended: a plate for looking, not for keying out. The plant takes about 33% of the sheet, centred near the centre — the easy measure most florists kept to. Cover the margins with your thumb and the plate suffocates; uncover them and the flower breathes again.
Line and Colour
Eighteenth-century plates are mostly copper engraving: hatched lines for shadow, then hand-colouring by another hand. 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
天地有大美而不言，四时有明法而不议。
—— 《庄子·知北游》
Heaven and earth have great beauty and do not speak.
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
The symbolism of such a plate lies not in flower lore but in record: the belief that a plant deserves to be drawn accurately — the plainest ethic of the scientific age. Meanings change their tune: the same flower can say opposite things within a century.
Season and Place
the rest of the year it is only a mass of leaves. Various: local hillside or a plant brought from overseas. The nineteenth-century botanic garden and glasshouse were their first address away from home. The year 1781 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. The volume was made in 1781-1793, when most of this knowledge came from living plants under glass.
The Book and the Hand
“Icones Plantarum Rariorum” was drawn by Nikolaus Joseph Freiherr von Jacquin and published 1781-1793. This plate is Plate 538. The image is public domain; the hand-colouring is still one person's hand.
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. A flora exists to be consulted; look long enough and you forget to consult — someone in 1781 gave a whole day to a single flower.
