Ludwigia octovalvis (1719)
Ten ways of seeing
- measured cast amber
- slightly upright 1.29 : 1
First Look
论画以形似，见与儿童邻。
—— 宋·苏轼《书鄢陵王主簿所画折枝》
To judge painting by likeness alone is the view of a child.
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 Ludwigia octovalvis: 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 毛草龙 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour covers 7.6% of the sheet, foliage 5.4%, the cast amber with a second note of 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 slightly tall. No details are appended: a plate for looking, not for keying out. The plant covers only 15% of the sheet, centred near the centre; the emptiness is where the eye rests.
Line and Colour
Eighteenth-century plates are mostly copper engraving: hatched lines for shadow, then hand-colouring by another hand. Craft leaves franker evidence than inscriptions. 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
海客谈瀛洲，烟涛微茫信难求。
—— 唐·李白《梦游天姥吟留别》
Seafarers talk of Yingzhou, lost in mist and waves, truly hard to find.
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 1719 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. The bud and the ripe fruit on one branch tell the season; the name in the title often tells the journey.
The Book and the Hand
“Dissertatio de generatione et metamorphosibus insectorum Surinamensium” carries only Maria Sibylla Merian'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
Appreciation is not knowledge but habit — one more look each time. A flora exists to be consulted; look long enough and you forget to consult — someone in 1719 gave a whole day to a single flower.
