Pentastemon argutum (1848-1849)
Ten ways of seeing
- slightly upright 1.27 : 1
First Look
凡画山水，意在笔先。
—— 唐·王维《山水论》
In painting, the intention precedes the brush.
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 Pentastemon argutum: the first word is the genus it belongs among, the second the epithet that sets it apart. Two words carry a whole provenance. No established Chinese name exists, so it is cited by its binomial alone.
Form and Colour
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
Slightly taller than wide, the plant set a little above centre. No details are appended: a plate for looking, not for keying out. Old plates set the plant slightly off centre, with unequal margins — that small imbalance is what keeps it alive.
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
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 1848 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
“Flore universelle” carries only Jean Baptiste Louis Letellier'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. A flora exists to be consulted; look long enough and you forget to consult — someone in 1848 gave a whole day to a single flower.
