Kingdonia uniflora Balfour f. et W. W. Smith is an endemic plant in China. From known records,
its distribution is more or less continuous through north-western Yunnan, western Szechwan,
southern Kansu and western Shensi. The plant occurs at an elevation of about 3000 meters in the
humus of the virgin forest in mountainous areas where the humidity is relatively high and the
temperature is low. It grows in the shade of forest and on acidic soil. Kingdonia is an herbaceous
perennial with a slender, branching rhizome. The annual shoot bears 2–3 cataphylls, 6–12 scales, 1
foliage leaf, a solitary flower with a long pedicel, a terminal and several lateral buds, and 2–12
internodal roots. Some lack the floral organ. Occasionally a shoot develops 2–3 normal foliage
leaves. The more or less round shaped foliage leaf is divided into 5 lobes and exhibits the typical
open dichotomous venation. It has a long petiole and a sheath-like leaf base. The solitary flower
carries 4–7 tepals, 8–13 staminodes, 3–8 normal stamens, and 4–9 apocarps, all spirally arranged on
the bulging receptacle. The fruits are aggregated ackenes with one seed in each single fruit. The
open dichotomously-veined foliage leaves as well as other primitive characteristics of Kingdonia
uniflora have attracted interest of the morphologists and taxonomists in China and abroad. The
morphological and ontogenetic studies of various organs of this plant are in progress. The present
paper is introductory in nature.
