Parthenocissus tricuspidata

Parthenocissus tricuspidata is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Parthenocissus tricuspidata rather than just read about it. In short: Parthenocissus tricuspidata is a species of flowering plant in the grape family (Vitaceae) native to eastern Asia (Korea, Japan, and northern and eastern China), where it thrives in floodplain bushes, riverside woodland and moist mountain mixed forests. Although unrelated to true ivy, it is commonly known as Boston ivy, grape ivy, Japanese ivy, and also as Japanese creeper, and by the name woodbine (though the latte…

Reference excerpt

Parthenocissus tricuspidata is a species of flowering plant in the grape family (Vitaceae) native to eastern Asia (Korea, Japan, and northern and eastern China), where it thrives in floodplain bushes, riverside woodland and moist mountain mixed forests. Although unrelated to true ivy, it is commonly known as Boston ivy, grape ivy, Japanese ivy, and also as Japanese creeper, and by the name woodbine (though the latter may refer to a number of different vine species). The specific epithet tricuspidata means three-pointed, referring to the leaf shape. Boston ivy is readily distinguished from the Virginia creeper (Parthenocissus quinquefolia) by its simple leaves with pointed lobes (Virginia creeper leaves are divided into five separate leaflets).

Description It is a deciduous woody vine growing to 30 m tall or more given suitable support, attaching itself by means of numerous small branched tendrils tipped with sticky disks. The leaves are simple, palmately lobed with three lobes, occasionally unlobed or with five lobes, or sufficiently deeply lobed to be palmately compound with (usually) three leaflets; the leaves range from 5 to 22 cm across. The upper side of the leaf blade is shiny and bare, the underside is dull green and only has sparse hairs on the leaf veins. The leaf color is initially reddish green to bronze during budding, then orange-yellow to intense scarlet in autumn. Stipules are present.

Inflorescences The greenish flowers are inconspicuous, greenish, in clusters; the inedible fruit is a small dark blue grape 5–10 mm diameter. The cup-shaped calyx is truncated. The hood-shaped petals are laid back. There are short stamens. The two-chambered, lobed ovary with a short style and capitate stigma is superior. There is a discus (circular fused anthers).

Cultivation and uses

P. tricuspidata uses adhesive pads to attach to surfaces, allowing it to climb vertically up trees, walls, and other structures. Contact with a surface signals the adhesive pads to secrete mucilage through microscopic pores which dries and creates a robust adhesive bond. The ability of a single adhesive pad to support thousands of times their weight may be explored as a model for new biomimetic materials. In its native range, the vine has traditional medicinal uses (China, Korea) and as a culinary sweetener (Japan). Both within and outside of East Asia, the plant is primarily used as an ornamental plant. Cultivars include 'Veitchii'. Like the related Virginia creeper, P. tricuspidata is widely grown to cover the façades of masonry buildings. This usage is actually economically important because, by shading walls during the summer, it can significantly reduce cooling costs. While it does not penetrate the building surface but merely attaches to it, nevertheless surface damage (such as paint scar) can occur from attempting to rip the plant from the wall. In the U.S., Boston ivy is used on the brick outfield walls at Wrigley Field of baseball's Chicago Cubs along with Japanese bittersweet (Celastrus orbiculatus).

Names and etymology

Parthenocissus is derived from the Greek terms parthenos (παρθένος; "maidenly, chaste, virgin") and kissos (κισσός; "vine") and means approximately "virgin ivy" (hence the common name of the related "Virginia creeper"). Tricuspidata, meaning approximately "with three points", comes from the Greek and Latin prefix tri ("three") and the Latin cuspidata ("tipped, pointed"). In Mandarin Chinese, the plant goes by a number of names, most commonly páqiánghǔ (爬墙虎, lit. "wall-climbing tiger"), but also páshānhǔ (爬山虎, lit. "mountain-climbing tiger", also refers to Hedera helix), dìjǐn (地錦, lit. "earth brocade", the name used in the Compendium of Materia Medica and the common name in Taiwan), tǔgǔténg (土鼓藤, lit. "dirt drum vine") and hóng pútáo téng (红葡萄藤, lit. "red grapevine"). In Taiwanese Hokkien, the vine also has several names, including chhiûⁿ-piah-tîn (牆壁藤, lit. "wall vine"), peh-soaⁿ-hó͘ (𬦰山虎, lit. "mountain-climbing tiger"), âng-koah (紅葛, lit. "red vine"), thô͘-kó͘-tîn (土鼓藤 lit. "dirt drum vine", a cognate with the Mandarin) and âng-kut-chôa (紅骨蛇, lit. "red-boned snake", a name that refers to at least five other plants as well). In Korean, the plant is called damjaeng'ideonggul (담쟁이덩굴) in reference to it growing on walls. In contexts of Korean traditional medicine, it is known as jigeum (지금/地錦, a cognate with the Mandarin Chinese dìjǐn from the Compendium of Materia Medica, as well as other names such as nakseok (낙석/絡石), jangchundeung (장춘등/長春藤), pasanho (파산호/爬山虎), naman (나만/蘿蔓) and yongninbyeongnyeo (용린벽려/龍鱗薜荔). In Japanese, the vine is known usually as tsuta (蔦; つた;ツタ), but also as amazura (甘葛; あまづら; アマヅラ), lit. "sweet vine" natsuzuta (夏蔦; なつづた; ナツヅタ), or rarely jinishiki (地錦; じにしき;ジニシキ). In Okinawan, the vine is called cita (蔦; つぃた), while in the Taiwanese indigenous language Paiwan it is tiyaroromao.

Worked examples

Example 1 — a first encounter with Parthenocissus tricuspidata

Start with the simplest possible case. Write down what Parthenocissus tricuspidata claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Parthenocissus tricuspidata before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Parthenocissus tricuspidata ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Parthenocissus tricuspidata

In research: Parthenocissus tricuspidata appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Parthenocissus tricuspidata in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Parthenocissus tricuspidata is common in secondary-school and first-year university syllabi. It links to neighbouring topics Flora of China, Flora of Japan, Flora of Korea, so understanding it makes those chapters shorter.
In everyday life: Look for Parthenocissus tricuspidata outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
