E. Asia (Japan; China: Fukien; Ryukyu Is.), SE. Asia (Tonkin; India: Sibpur, Dehra Dun, Peshawar, etc.; Ceylon), also in Africa and Australia; in Malesia: Malay Peninsula (Singapore; Selangor; Kuala Lumpur; Malacca), E. Java (near Surabaja and near Redjasa E of Pasuruan), Kangean Is. (Sepandjang), Lesser Sunda Is. (Flores: Rana Mesé), Philippines (Central Luzon: Pampanga, Bulacan, Rizal).
BACKER & BAKHUIZEN f. note this also from Mts Jang & Idjen in E. Java at 2200 m, but I believe this to be an error.

Notes

The specimens of W. globosa of Malesia are c. 1½ times as long as wide, while the Australian specimens are usually twice as long as wide. The size of both the Malesian and Australian plants of W. globosa is smaller than that of W. arrhiza. In Australia still another Wolffia is found with an elliptic dorsal outline and which is much higher than all other species in the genus. It is known as W. arrhiza var. australiana BENTH. but no doubt represents a good species ().
