Mr. Thelluson’s Purslane

Twelve ways of seeing

• measured cast red
• upright 1.66 : 1
• published 1829
• Plate 743

Not a catalogue entry but a way of looking: how to stand, what to notice, how the line was cut, when it flowers, where it came from, who made it — and then the poems and the classics that taught China to see the same flower. Read the twelve in order and the plate opens.

1. 01

   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.

   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

   No reliable binomial survives, so the printed title must serve. Neither name nor binomial survives: the printed title must do.

3. 03

   Form and Colour

   Measured on this plate: flower colour covers 13.9% of the sheet, foliage 0.0%, the cast red. 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.

4. 04

   Composition

   Tall and narrow, the plant rising in one movement with generous margins — the upright format of most floras. (about 1.66 : 1) No details are appended: a plate for looking, not for keying out. The plant covers only 24% of the sheet, centred above centre; the emptiness is where the eye rests. Blank paper is not unfinished work: it is where the eye rests.

5. 05

   Line and Colour

   The first half of the nineteenth century moved from copper to steel to lithography; stipple could render the softest transition. Craft leaves franker evidence than inscriptions.

6. 06

   Season

   Plates usually record flowering, the fortnight when a plant is most identifiable; the rest of the year it is only a mass of leaves. The year 1829 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. The best time to read such a plate is its flowering season: three minutes under the tree explains what no text can.

7. 07

   Provenance

   Various: local hillside or a plant brought from overseas. The nineteenth-century botanic garden and glasshouse were their first address away from home. In the same volume the kin are shelved together; set several plates side by side.

8. 08

   The Book and the Hand

   “Edwards' Botanical Register” was drawn by Sydenham Edwards, John Lindley and published 1829-1847. This plate is Plate 743. The image is public domain; the hand-colouring is still one person's hand.

9. 09

   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 corolla becomes its resting point.

    The Written Tradition

    人无癖不可与交，以其无深情也。

    —— 明·张岱《陶庵梦忆》

    Never make a friend of a man without an obsession: he has no deep feeling.

    China had the Bencao Gangmu and the Illustrated Study of Plant Names and Realities; Europe moved from herbal woodcuts to chromolithography. Both trusted pictures to finish what words could not. You need not parse every word: take the line, and the flower acquires a second face.

11. 11

    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.

    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 1829.
