Bignoniae Nova Specie [Rhigozum obovatum] (1817)
Ten ways of seeing
- measured cast yellow-green
- slightly upright 1.24 : 1
First Look
竖划三寸，当千仞之高；横墨数尺，体百里之迥。
—— 南朝宋·宗炳《画山水序》
A vertical stroke of three inches stands for a cliff of a thousand fathoms; a few feet of ink holds a hundred li.
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
No reliable binomial survives, so the printed title must serve. The Chinese name 倒卵叶刺钟木 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour covers 9.0% of the sheet, foliage 5.3%, the cast yellow-green with a second note of amber. 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. 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 19% of the sheet, centred above centre; the emptiness is where the eye rests.
Line and Colour
The first half of the nineteenth century moved from copper to steel to lithography; stipple could render the softest transition. 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: 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. In a flora it is a species first and a symbol second; the order is worth keeping.
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 1817 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
“Drawings of plants collected at Cape Town” carries only Clemenz Heinrich Wehdemann'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
Appreciation is not knowledge but habit — one more look each time. Two centuries on, the plant may still flower in some garden; the one on this sheet stopped in the season of 1817.
