Quamoclit foliis digitatis, pentaphyllos, pedunaculis unifloris, flore dilute purpurascente – Ipomoea (1772-1793)
Ten ways of seeing
- upright 1.54 : 1
First Look
夫象物必在于形似，形似须全其骨气。
—— 唐·张彦远《历代名画记》
Likeness is the threshold; bone-and-breath is the point.
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
Only the genus Ipomoea is given; species-level names came later. No established Chinese name exists, so it is cited by its binomial alone.
Form and Colour
Garden annuals and low perennials: many small, brilliantly coloured flowers to a stem, with leaves palmately lobed, pinnate or entire — the mainstay of the Victorian bedding scheme.No colour group is recorded. A single plant, laid out with nothing hidden.
Composition
Tall and narrow, the plant rising in one movement with generous margins — the upright format of most floras. 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
Eighteenth-century plates are mostly copper engraving: hatched lines for shadow, then hand-colouring by another hand. Decide first whether it was printed or painted; only then discuss whether it is beautiful. 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
词藻世传平子赋，园林人比郑公乡。
—— 唐·皇甫冉《館陶李丞舊居》
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
Bedding plants carry no imperial weight; they mean the everyday — window sill, border, festival, gift. Victorian floriography grew up among exactly these flowers. Meanings change their tune: the same flower can say opposite things within a century.
Season and Place
under glass they could be had from March. Gathered from everywhere by plant hunters and the glasshouse trade: pelargoniums from South Africa, campanulas from European mountains, lobelias from North America, fuchsias from Chile. The year 1772 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
“Hortus Romanus juxta systema Tournefortianum” carries only Giorgio Bonelli's name. The image is public domain; the hand-colouring is still one person's hand.
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 1772.
