Distribution
China. Abelia uniflora is a relictual species that is localised in the Wuyishan, extending from Fujian, Jiangxi and Zhejiang to southern Anhui.
Ecology
Mixed forest; 600 – 1,200 m.
Morphology Branches
Young branchlets glabrescent or densely short pilose with erect or hooked hairs
Morphology General Buds
Winter buds with several pairs of ciliate and pubescent perulae
Morphology General Habit
Small to large erect shrubs 100 – 150 cm tall
Morphology Leaves
Leaf blade sparsely hairy, base of main vein usually densely covered with tufts of hairs Leaf margin entire, with a few irregular gland-tipped teeth, incised or crenate Leaves ovate, rarely elliptic, 8 – 38 mm long, 4 – 20 mm wide, acute to acuminate at apex, rounded to cuneate at base
Morphology Leaves Petiole
Petioles short to 2 mm long
Morphology Reproductive morphology Flowers
Flowers axillary, solitary along new shoots
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 4, didynamous and inserted within the corolla tube
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments adnate to lower part of corolla tube, hairy basally
Morphology Reproductive morphology Flowers Calyx
Calyx lobes 2, often notched and deeply lobed and appearing as 3 to 4 sepals Sepals ovate to lanceolate 8 – 10 mm long, 4 – 5 mm wide, obtuse or acute at apex, cuneate at base
Morphology Reproductive morphology Flowers Corolla
Base of corolla tube bulging ventrally with a nectary composed of dense glandular hairs, nectary to 1 mm in diameter Corolla lobes subequal, ovate, 2 – 3 mm long and slightly recurved Corolla tube 4 – 7 mm long, abruptly expanding to the corolla mouth up to 8 mm in diameter Corolla bilabiate and infundibuliform, 14 – 24 mm long, pink-purple, throat and lower corolla lobes bearded and with yellow markings
Morphology Reproductive morphology Flowers Epicalyx
Epicalyx of 4 equal prophylls, episepals triangular-lanceolate to 1 mm long and with a ciliate margin
Morphology Reproductive morphology Flowers Gynoecium
Style glabrous, inserted to slightly exserted from the corolla tube, stigmas capitate, white and papillose
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary lanceolate-fusiform to short-ovate with a short terminal sterile neck, densely hispid to glabrescent Ovary longitudinally ribbed, ventrally compressed and widened along the fertile locule, 3 – 6 mm long
Morphology Reproductive morphology Fruits
Fruit an achene with persistent, slightly accrescent and spreading sepals Achenes 1-seeded to 8 mm long, flattened ventrally and ridged.
Morphology Reproductive morphology Inflorescences Peduncles
Peduncles densely pilose, 2 – 3 mm long and with a pair of reduced leaf-like bracts at base
Note
Abelia uniflora is morphologically very similar to A. macrotera and differs by the hairy stems and lobed sepals. A clear disjunction between A. macrotera in western China and A. uniflora in eastern China exists and follows the distribution of A. chinensis This species was named in comparison with the species Zabelia triflora and differs by having single flowers.
Phenology
Flowering June – Sept. Fruiting Oct. – Dec.
