Catasetum trimerochilum
Ten ways of seeing
- measured cast yellow-green
- upright 1.57 : 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.
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 where the yellow is deepest: the whole tonal order is measured from that patch.
Name and Thing
The binomial is Catasetum trimerochilum: 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 瓢唇亚族 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour covers 20.3% of the sheet, foliage 21.4%, the cast yellow-green with a second note of amber. No other plate shares exactly this measure. Orchids carry pseudobulbs or fleshy roots; six tepals, one modified into a lip that serves as a landing stage, and a column uniting stamens and pistil — a structure unique to the family. Filed under yellow — a honey-yellow, built in washes from a pale ground. A single plant, laid out with nothing hidden.
Composition
The sheet is tall. No details are appended: a plate for looking, not for keying out. The plant fills 46% of the sheet, centred near the centre — the herbarium way, drawn to be read whole.
Line and Colour
In the later nineteenth century chromolithography took over: colour printed rather than painted, line demoted. 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: block in the broad shapes and colours first, detail last; lithographic softness comes from thin washes — two or three pale layers will get you close.
Poetic Resonance
扈江离与辟芷兮，纫秋兰以为佩。
—— 战国·屈原《离骚》
I gird on river angelica and secluded angelica; I twist autumn orchids into a chaplet to wear.
The poem gives the mood first and the picture supplies the form; set the line beside the plate and the yellow the corolla becomes its resting point.
Symbolism
In China the orchid is the gentleman who blooms unseen; in Victorian Europe it was luxury and obsession, a single new species worth a fortune. This plate leans yellow, which in flower language adds one more degree of feeling. In a flora it is a species first and a symbol second; the order is worth keeping.
Season and Place
Varies by genus: temperate terrestrials flower in spring and summer, tropical epiphytes almost year-round. Worldwide, richest on tropical mountains. Chinese cymbidiums come from the hills of the south. The year 1854 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
“L'Illustration horticole” carries only Charles Antoine Lemaire's name. The image is public domain; the hand-colouring is still one person's hand.
What to Take Away
Carry three rules away: whole before detail; line before colour; picture before book. Two centuries on, the plant may still flower in some garden; the one on this sheet stopped in the season of 1854.
