Dracontium lanceaefolium
Ten ways of seeing
- measured cast yellow-green
- upright 1.74 : 1
First Look
六法者何？一、气韵生动是也；二、骨法用笔是也；三、应物象形是也；四、随类赋彩是也；五、经营位置是也；六、传移模写是也。
—— 南齐·谢赫《古画品录》
The six laws: spirit resonance alive; bone-method in the brush; matching form; colour by kind; planning the placing; copying the masters.
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 where the yellow is deepest: the whole tonal order is measured from that patch. 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 Dracontium lanceaefolium: 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 龙根天南星 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour covers 17.8% of the sheet, foliage 9.6%, 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. Filed under yellow — a honey-yellow, built in washes from a pale ground. 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 takes about 31% of the sheet, centred a little right of centre — the easy measure most florists kept to.
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
朝饮木兰之坠露兮，夕餐秋菊之落英。
—— 战国·屈原《离骚》
At dawn I drink the dew fallen from magnolia; at dusk I dine on the fallen petals of autumn chrysanthemum.
The poem gives the mood first and the picture supplies the form; set the line beside the plate and the yellow 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. This plate leans yellow, which in flower language adds one more degree of feeling. 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. 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
“Icones Plantarum Rariorum” carries only Nikolaus Joseph Freiherr von Jacquin's name. A plate is collective work: drawer, engraver and colourist were different hands, and the unnamed ones decided how good it looks.
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 1781.
