 unequal. Ovary 3-celled; style short, 3-cleft; ovules i in each cavity. Capsule 

 inflated, 3-lobed. Seeds arilled at the base; cotyledons conduplicate. [Greek, 

 heart- seed.] About 15 species, of warm and temperate regions. 



i. Cardiospermum Halicacabum L. BALLOON VINE. HEART-SEED. (I. F. f.

Family 12. BALSAMINACEAE Lindl. 

 Jewel-weed Family. 



Succulent herbs, with alternate thin simple dentate petioled leaves, 

 and showy very irregular axillary flowers. Sepals 3, the 2 lateral ones 

 small, green, nerved, the posterior one large, petaloid, saccate, spurred, 

 Petals 5, or 3 with 2 of them 2-cleft into dissimilar lobes. Stamens 5, 

 short ; filaments appendaged by scales on their inner side and more or 

 less united ; anthers coherent or connivent. Ovary oblong, 5-celled ; 

 style short, or none ; stigma 5-toothed or 5-lobed ; ovules several in each 

 cavity. Fruit in the following genus an oblong or linear capsule, elasti- 

 cally dehiscent into 5 spirally coiled valves, expelling the oblong ridged 

 seeds. Endosperm none ; embryo nearly straight ; cotyledons flat. 

 Later flowers small, cleistogamous, apetalous. About 220 species, mostly 

 natives of tropical Asia. The family consists of the following genus and 

 the monotvpic Asiatic Hydrocera.
