Data deficient (DD) (IUCN 2000). Begonia kingdon-wardii apparently has a very restricted distribution having been collected on only two occasions, from localities about 40 miles apart. However, despite the scarcity of herbarium collections and the fact that it has not been recollected since 1937, its habitat is remote and not believed to suffer from strong human pressures.
Endemic to the northern part of Myanmar's Kachin state
It occurs at an altitude of 900 m in the mountains to the east of the town of Putao. Here it is found on shaded earth banks and on rocks in evergreen rainforest.
Morphology General Habit
Rhizomatous creeping herb, rooting at nodes; rhizome c. 4 mm in diameter, few branched, internodes 0.5 - 1.5 cm long, glabrous or with a very sparse covering of microscopic glandular hairs
Morphology Leaves
Leaves alternate; petioles continuing straight into main vein of blade, 7 - 9 cm long, c. 2 - 4 mm in diameter, usually glabrous, occasionally with a few microscopic glandular hairs in the uppermost portion; blade erect, upper surface glossy dark green with paler intervenal bands, lower surface deep red, glabrous or occasionally with a few microscopic glandular hairs along the main veins, elliptic or ovate-elliptic, 8.5 - 11 x 6.5 - 9.5 cm, apex acute to rounded, base symmetric, obtuse or occasionally very shallowly cordate, sinus 2 - 4 mm deep, margin crimped, veins 5 - 6, palmate
Morphology Leaves Stipules
Stipules persistent, lanceolate, 0.9 - 1.2 x 0.3 - 0.4 cm, apex long setose, both surfaces covered with microscopic glandular hairs, margin entire, glabrous
Morphology Reproductive morphology Flowers
Male flowers: perianth segments 4, white, outer 2 broadly elliptic, 1.3 - 1.6 x 1.2 - 1.7 cm, apex rounded, inner 2 elliptic, 0.8 - 1.1 x 0.55 - 1 cm, apex rounded; stamens c. 75, forming a symmetric dome-shaped mass; filaments c. 1.5 mm long, free, borne on a c. 1 mm tall torus, anthers oblong-obovate, c. 2 x 0.75 mm, dehiscing via vertical splits along sides of locules, connectives projecting c. 0.5 mm, apices rounded
Morphology Reproductive morphology Flowers Pedicel
Pedicels covered with microscopic glandular hairs, those of male flowers 1.5 - 3.5 cm long, those of female flowers c. 2.5 cm long
Morphology Reproductive morphology Fruits
Fruit 4-locular; rhomboid, c. 1.5 x 0.6 cm, indistinctly 4-angular, with a short triangular wing in upper half of each angle, wings c. 3 x 4 mm; styles not observed.
Morphology Reproductive morphology Inflorescences
Inflorescences axillary, unisexual, males in 5 - 9-flowered dichasia, female flowers solitary; peduncle c. 6 cm long in male inflorescences; bracts persistent, ovate, to 1.5 x 0.3 cm, apex acute, margin entire, both surfaces sparsely covered with microscopic glandular hairs
The species appears to have only been collected on two occasions, both times by Frank Kingdon-Ward.
