Fam. 128. BALSAMINACEAE Tsuri-fune-so Ka Balsam Family 



Soft, juicy herbs; leaves alternate or opposite, simple, penninerved, exstipulate; flowers zygomorphic, bisexual, solitary, race- 

 mose, or nearly umbellate; sepals 3, rarely 5, imbricate, unequal, the lowest with a spur; stamens 5, the filaments short, connate 

 at the tip; ovary superior, 5-locular; stigmas 1-5, sessile; ovules many; fruit a juicy 5-valved capsule which suddenly explodes 



at maturity, casring the seeds for a considerable distance; seeds without endosperm, the embryo straight. Two genera, with 



about 400 species, chiefly in tropical Asia and Africa, a few in temperate regions. 



1. IMPATIENS L. 



TsURI-FUNE-s6 ZOKU 



Soft juicy annual herbs, somedmes somewhat woody at the base; leaves alternate, opposite, or radical, serrate, often with 

 glands near base of the pedoles; peduncles axillary, solitary or in fascicles; flowers on slender pedicels, zygomorphic, usually 

 large and showy, purple, yellow, or white; sepals 3, rarely 5, often colored, the lateral 2 reduced, the lower one largest, spurred; 



petals 3, the lateral ones bifid; capsules loculicidally dehiscent. About 400 species, chiefly in tropical Asia and Africa, a few 



in e. Asia, Europe, and N. America.
