Cultivar or taxon

 

Clausena lansium (Lour.) Skeels (sec. Swingle and Reece 1967; sensu Tanaka sec. Cottin 2002)

Description

 

Crown compact or dense, not weeping. First-year twig surface pubescent; thorns absent or not persistent; prickles absent or not persistent. Petiole length long; wings absent. Leaflets five to seven or greater than seven, margin entire or crenate/crenulate, rachis wings absent. Fruit broader than long, as broad as long, or longer than broad; rind red or pink, green-yellow (6), yellow (7-10), or yellow-orange (11); rind texture smooth (1-3); firmness membranous; navel absent; flesh red/purplish-tinged or yellow.

Swingle and Reece (1967) provided the following additional notes on the species:

"Oliver (1861, p. 34) gave a Latin diagnosis of this species that, translated, reads as follows: "Tree or shrub; branches at first pubescent or puberulous; leaves 5-7-9-foliolate, 20-25 cm long; leaflets ovate-elliptic, lanceolate or ovate, with petiolules 2-6 mm, more or less oblique at the base, apex obtuse or subemarginate, sometimes almost mucronulate, slightly acuminate, margin undulate-crenate or slightly serrulate, becoming glabrous or glabrescent, the midrib and veins often sparsely scabrous, glabrescent below; terminal leaflet often 6-10 cm long; flowers subsessile or shortly pedicellate, in many-flowered cymose panicles; calyx-5- (rarely 4-) merous, lobes triangular or ovate; stamens 10, alternate ones shorter, filaments dilated above the middle, flattened, subulate above, anthers oblong or elliptic, cordate-sagittate at base, with a dorsal gland; ovary shortly stipitate, glandular, very often 5-locular, ovules in pairs [in each locule], superposed, the upper one peltate on the side or toward the base, the lower one subpendulous; style very short, distinct, glabrous above, stigma 5-lobed, slightly wider than style; fruit usually with 5 locules, 5-seeded, or by abortion 1-seeded, or sterile, ovoid-globose, pubescent, 1 in. [25 mm] or less diam.; cotyledons fleshy, equal."

This species differs widely from all the other species of the genus....The wampee is a highly esteemed fruit tree in southern China, where sour, subacid, and sweet varieties are known. The white or yellow fruits are ovoid or subglobose, about the size of a pigeon’s egg, but varying in size and shape with the variety cultivated. The inflorescences are large panicles at the ends of the branches, so the fruits occur in rather openly-spaced clusters. In texture, the wampee fruit is much like a loquat and is a berry without a tough peel. An illustrated treatise in Chinese by Mill Tsen [Ts’êng Mien-chih, in Mandarin transliteration] (1936) described in detail six varieties and figured the fruit and a leaflet of each variety."

Notes

 

Swingle and Reece (1967) additionally noted that:

"According to Mill Tsen, Professor Wên Wên-kuang of Sun Yat-sen University at Canton, China, listed eight varieties of the wampee grown in Kwangtung Province. These varieties are not described in detail but are given long descriptive names such as "white-hairy-chicken-heart-sweet-wampee"; "long-chicken-heart-sour-wampee"; "yellow-hairy-chicken-heart-sour-wampee," etc.

Although the wampee is only remotely related to Citrus, it can be grafted on a Citrus rootstock, and is thereby forced into early flowering and fruiting. The rough lemon can be grafted on the wampee and will grow for many years if a small branch of the wampee is allowed to grow just below the graft. Any desired Citrus fruit can be top-grafted on the rough lemon and may live for many years and may even be made to fruit. However, the graft union of the rough lemon on the wampee is poor and badly overgrown. Wampee on Citrus seems to make a much better and more permanent union."
