Dendrobium thyrsiflorum
Ten ways of seeing
- measured cast yellow-green
- upright 1.44 : 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.
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 green is deepest: the whole tonal order is measured from that patch.
Name and Thing
The binomial is Dendrobium thyrsiflorum: the first word is the genus it belongs among, the second the epithet that sets it apart. The genus name Dendrobium: Dendrobium joins dendron (tree) and bios (life): life upon trees. The Chinese name 球花石斛 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour covers 10.0% of the sheet, foliage 21.8%, 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. a moss green. Three things fix the habit: leaf arrangement, tepal count, and how the flower is borne.
Composition
The sheet is tall. No details are appended: a plate for looking, not for keying out. The plant fills 44% 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
江有香草目以兰，黄鹄高飞离哉翻。
—— 两汉·佚名《临高台》
The poem gives the mood first and the picture supplies the form; set the line beside the plate and the green 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. Meanings change their tune: the same flower can say opposite things within a century.
Season and Place
Varies by genus: temperate terrestrials flower in spring and summer, tropical epiphytes almost year-round. the orchids drawn for European portfolios came largely from the cloud forests of Central America and Southeast Asia. The year 1885 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. Read the locality and the flowering season both with a discount: one is hearsay, the other a ten-day peak.
The Book and the Hand
“Lindenia: Iconography of the Orchids” carries only Jean Jules Linden's name. The image is public domain; the hand-colouring is still one person's hand.
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. The flower of that year is dust, yet its image on paper has outlived every living cousin.
